How to set up raid??

hi
can anybody help me with setting up a raid ?
i dont know alot about hardware so ill be so glad if anyone can help
thanks alot

I never used your specific board so you will need to go and find the specific settings yourself, but there is the prinicple behind it.
You have a RAID controller which displayes virtual HDDs to the operating system.
The operating system does not know how many physical disks make up each virtaul one (reffered to as an array).
The steps are:
-Install the disks
-Go to the RAID bios (if you have more than one RAID controller they all need to be connected to the same one and you need to use the right bios)
-Setup one or more arrays using these disks
-Start the operating system instalation and supply the RAID drivers when promptede (right at the begining when you are asked to press F6 to sipply RAID or SCSI drivers). These drivers must be on a floppy!
-Create a partition on the desired array and format it.
-Install the OS.

What are the procedures and settings to set up RAID 5 in Windows 8?
I would not do it... Throw in one more spindle and build RAID10 (or Storage Spaces equivalent of it). There are very few workloads working well with parity RAIDs and also single parity RAID has own issues with modern high-capacity spindles (slow rebuild
times, silent bit rot, high chances of a double failure etc). See:

How to set up email in RAID Admin?

Using RAID Admin 1.5.1, I need to know how to set up the it up for automatic email notification. Okay I got as far as clicking the Email icon adding my .mac address. Now what do I put under SMTP. It's asking for the "server" and the "from email address". Our company uses a Microsoft Exchange server whether or not that means anything. And what is up with the check box for SMTP Server Authentication?
Thanks for any input. I appreciate it!

Thanks Donald for answering my question. I found the IP Address of our exchange server and I plugged that into the server field. And I plugged my own company email address into the "From Email Address" field. That didn't do it, so I plugged in my network username and password into the authentication fields. I clicked "Send Test Email" again. Still didn't work. But here is the key in case anyone else has problems. At least in my case, I had to click the "OK" button to verify my settings. Once verified, I went back into the email settings and clicked "Send Test Email" again. Voila! A test email ended into my .mac email account right onto my iPhone within 1 minute. I think this is so cool. I can be away from the office (whether I be skiing or golfing) and be notified instantly if one of the components start to fail on our Xserve RAID system. Awesome!!!!!!!

I set up Raid on my Mac Mini Server and lost my Server software. It is not listed in my "purchased" apps. How can I get it w/o having to purchase it? Will my serial # be enough to show it is a mini server and under warrantee be enough to get it back?

If it's not listed in Purchases, check that it's hidden, and if so, unhide it > http://support.apple.com/kb/HT4928 After that, go to Purchases and download OS X Server.
If you can't download it, contact with the Mac App Store support > http://www.apple.com/support/mac/app-store/contact

How to delete a RAID set in Disk Utility?

I set up a mirrored RAID set with two 80GB disks on a 500MHz G4 "sawtooth", then installed Tiger successfully. Statup Disk on the Tiger DVD recognizes it as a valid startup disk, but it won't boot (stays on the white screen with the large apple).
So, I decided to go back to two separate disks with no RAID, but Disk Utility won't seeem to let me delete a RAID set. It shows the volumes as locked (no apparent way to unlock them), and also doesn't allow me to format the underlying drives (bad file descriptor error).
Any suggestions on how to undo a RAID set in Tiger?
Thanks,

Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. After the menubar appears select Disk Utility from the Utilities menu (Installer menu for Panther.) After DU loads select the main entry of the RAID (the one with the RAID size) then click on the RAID tab in the DU main window. Select the main RAID entry from the icon list (the one that says "Mirrored RAID Set" and should have the word "Online" in green. Then click the Delete button down below the list view.
Be sure to backup first because this could cause complete loss of data.

Hello everyone
I have been Building my own computers since 1997. (Remember Windows 3.11 and Dos 6.22 LOL)
but i have never tried to use Raid. i just got 2 SanDisk 128GB SSD drives,
i have read other things on this forum "970A-G46 raid issues"
But everything i have tried has not worked.
when i try to start the computer and hit Ctrl-F. it shows the hard drives. but i can't do anything.
I just don't understand what i am doing. I really would like someone to tell me step by step how to setup a raid 0.

Glad you were able to do it...I remember my first RAID 0 experiences...It's really funny when I recall the paranoia from folks who'd never done it themselves...like, for instance, the old wives' tail that states that with RAID 0 your odds of drive failure are multiplied 100% by the number of drives you have in the array... "If you lose one drive, you lose it all," etc., which seems to make sense until you consider the fact that if you have just one drive running in SCSI/IDE mode--and it fails--you also "lose it all"... Then there's the "But RAID 0 isn't fault tolerant" myth, which is true but still a myth because normal SCSI/IDE is also not fault tolerant...! The fact is that if you have 2 standard IDE/SCSI drives running compared with 2 drives running in RAID 0, there's no difference at all in the odds of a single drive failing at any time... The drives don't care whether you run them in RAID 0 or IDE, of course, etc. Drives always fail individually--almost never in pairs, of course--and so the odds of a RAID 0 drive failing are exactly the same as they'd be if you weren't running RAID 0 at all.
Anyway, I've included RAID 0 in every build I've done personally since 2004, and the interesting fact is (although mere coincidence) that on those rare occasions when a drive has failed it has not been one of my RAID 0 drives...!... Enjoy!

How we set up multiple websites on OSX Server

BACKGROUND
After fiddling and futzing around for weeks (actually since last year) I've finally figured out how to set up multiple websites (virtual sites) using one port and one IP address. While there seems to be lots of discussion on this topic, it seems that the basic assumption is that one knows everything about websites, DNS and all that stuff, which I do not.
When our network was originally established the engineer set up a wiki and also configured webmail, so we had two sites, one secured for mail and the other open for Calendar and the wiki. We were not hosting any websites locally because our school website is hosted by a company in New England.
This year I wanted to set up websites for teachers and students. As great as the wiki is, there are some things it just can't do as well as a website. So I figured if I set up the sites teachers could link back and forth from one to the other. In addition kids could now start to use a real website instead of the cobbled together file mess I had when we ran a Windows network. Also iWeb is a much more accessible tool than FrontPage.
SERVER SIDE:
Snow Leopard Server - 10.6.4
There are two - actually three pieces if you want your iWeb clients to connect to the server: Server Side Web Services, DNS and, in my case, FTP.
================================================ SERVER SIDE - WEB SERVICES
If you haven't turned on Web services, you'll need to open Server Admin and do that. If you don't know how to set up web services - just reply and I'll step you through that as well.
Once web services are set up and turned on, you'll see it listed under your server’s name in the Server Admin sidebar. Click on "Web" and then click on the "Sites" tab at the top of page. This is where you list all your sites.
Click the plus button and enter the fully qualified name of your site, for example: "students.myschool.org". Don't use the defaults here (no name) - that's what got me in trouble before. BE SPECIFIC!
You'll be looking at the "General" tab (the other tabs, "Options", "Realms", etc. we'll deal with in a second).
On the "General Tab", the default IP address ("any") and port (80) is just fine. We'll run everything over port 80. (Apache figures all the virtual site stuff out - you don't need your rocket science degree for that.)
"Web Folder:" is important because this is how you'll "segment" your websites. While I would NEVER do this again, we have a solid state hard drive for the OS and a RAID array for our data files. IF you have that, make sure you do NOT use the default "Web Folder" because it will store all your files on your solid state drive. There may not be enough room, over time, on that drive. I've not experienced it yet, but it's my understanding that if the drive fills up, the server shuts down.
I store my web sites on a folder on the RAID array.
Everything else on that tab can be left as the default. (Just make sure that you have an "index.html" or "index.php" file in your web folder root, but iWeb will take care of that for you.)
I would put in your email address in the "Administrator Email:" field.
Under "Options" you really don't have to put anything. I've tested making websites with iWeb and it doesn't appear that anything needs to be checked.
Nothing needs to be entered in "Realms" as well from what I see working w/ iWeb.
The defaults in "Logging" are fine.
You can leave "Security" alone, but we do have a (self-issued) certificate listed for our webmail site.
"Aliases" is important. Under "Web Server Aliases" you enter how you want the site to respond to when users type in a URL in their web browsers.
When our web server was initially set up the engineer set up "wiki.myschool.org" on port 80 and "mail.myschool.org" on port 443. In the aliases section was nothing but a "*" (the wildcard character). That means, from what I can figure out, that the webserver will respond to these sites regardless of what is typed in the URL. (Well, something like that - point is, if you create OTHER websites, you'll NEVER get to them because the wildcard character in the "Aliases" section, in effect, grabs those web requests and redirects them to the sites that are already there.
In my case I deleted both of those wild card characters. For my "wiki.myschool.org" site, I entered "mail.myschool.org". That means if you type EITHER "wiki." or "mail.", go to the site that’s stored in the “Web Folder” we set up when those sites were created.
For "mail.myschool.org" I just DELETED the wildcard character. I wanted that site (since it was secured) only to respond to "mail." - nothing else. (You're not going to that secured site for any other reason than to get your mail.)
"Proxy" can be left blank. Have no idea what that does. As time permits I'll do some research and figure out what it's used for.
"Web Services" is if you want to provide any MORE services to this particular site. Most likely you'll want to uncheck all the boxes. For our "wiki." site, we have checked "Wikis", "Blogs", and "Calendar". For our "mail." site we have those checked PLUS "Mail".
I would create a separate "Web Folder" for each of your sites. I don't know if that's a requirement but for housekeeping purposes, I would keep the sites separated. And I SUSPECT that it's "best practice" to separate your wiki from your other websites.
SERVER SIDE - DNS
OK...now you have to make your site reachable and the only way to do that is to set up DNS so that folks don't need to type in the IP address of your web server. You need to set up DNS inside your network and, if you want folks in the outside world to reach your website, you'll need to set up an external DNS as well. I'm going to cover INTERNAL DNS - if you don't know how to set up EXTERNAL DNS - reply or email me and I'll post those instructions.
Most likely you have already created Zones for you network...all you really need to do is create "Aliases" so that when you type "students.myschool.org" your web browser will know that site resides on IP address XXX.XXX.XXX.XXX.
If you've set up Zones then you already have a "Machine" setting that translates your server’s name to an IP address and vice versa.
All you need to do is create an "Alias" (CNAME) record for, in this case, "students". You’ll see the choices for types of records when you click the "Add Record" button.
There are only two fields to configure for a record: "Alias Name" - in this case "students" and "Destination" - in this case "servername.myschool.org". (You've already entered a machine record that says "servername" = 192.168.1.x.)
That's it for Internal DNS.
SERVER SIDE - FTP
Now you have to get iWeb to communicate with the webserver.
There are only three ways iWeb will communicate with webservers: MobileMe, Local Folder and FTP Server.
Local Folder is really only practical if you want to host a website on a laptop (I was blown away initially when I found out that all Macs had a built-in web server - how neat is that?). I think there are some very cool things teachers could do with configuration, and, of course, you wouldn't need to set up any web services on the web server, but that's for another discussion. You need to set up FTP services on the web server.
Turn on and enable FTP on your webserver.
You can leave the defaults for "General", "Messages" and "Logging". "Advanced" is the only thing you want to set. I set "Authenticated Users See:" to "Home Folder Only". I set the "FTP Root" to the same root folder in which I plan to store my web sites (/VOLUMES/RAID Array/WebServer/Documents). This setting sets that folder only to be accessible via FTP.
I would suggest returning to your DNS settings and adding one more "Alias". Set "ftp." to point to your webserver. Why? So folks can edit their sites from home (see below).
CAVEAT: If you are running FTP on other servers, make sure that the settings here do not conflict with the settings on the other servers. For example, I'm running FTP on my file server so that my scanners can communicate with it. However, I configure my FTP settings by machine name and NOT "ftp.myschool.org".
================================================
CLIENT SIDE - CONFIGURING iWEB
Now you have to configure iWeb so that it will communicate with your server.
Click on the "Site" icon so that "Site Publishing Settings" appears.
Publishing:
"Publish to:" = "FTP Server"
You can set the "Site name:" and "Contact email:" to whatever you want. But see below!
FTP Server Settings:
"Server address"=ftp.myschool.org (you could also enter in servername.myschool.org or the IP address. However, if you want folks to be able to work on the site from home, you will need to configure external DNS for that. If you use the IP address, you're out of luck for remote access to the site. (You can do it but it's beyond the scope of this discussion.)
"Username" & "Password" should be your user's network login credentials.
"Directory/Path" - this is important. Remember, you set your "FTP Root" to be "/VOLUMES/RAID Array/WebServer/Documents". If you leave this field blank then the website will be dumped into this folder. If you are only setting up one site, that may be OK. However I wanted to set up a "students" site folder, a "faculty" site folder and a separate site for our literary magazine.
THEREFORE: I have, in my ..../Documents folder (on the server), a "students" folder, a "faculty" folder, and a "litmag" folder.
SO...in my "Directory/Path:" field, I have "/faculty". That means the full path to this website is "ftp root/faculty" or "/VOLUMES/RAID Array/WebServer/Documents/faculty" (You don't need a trailing "/" character. iWeb will automatically append the folder for you user depending on what you entered in "Site Name:" in the "Publishing" area.
Website URL:
This is the root website depending on whether it is "students" or "faculty". Since iWeb will append the site name to this root website, I accomplished what I hoped to accomplish in this post (http://discussions.apple.com/message.jspa?messageID=12288561#12288561).
Faculty sites will be @ http://faculty.myschool.org/username. Students @ http://students.myschool.org/username. PERFECT!
iWeb is such a GREAT tool - NOW the kids can start using it!
I want to reiterate that this works for our school but it should work for you as well. There may be better ways to do this but it works for us.
Hope this has been helpful and you won't have to spend weeks trying to figure this all out by yourself!

OK...here's how we did it.
To get access to the website you created from outside your network there are a couple of steps.
First, you have to have a STATIC IP address from your ISP. If you have a T1 circuit, no problem...you usually get a couple of static IPs you can use. However, if you have a cable modem circuit, most likely you have a dynamic IP address which changes when you connect to the internet. Usually a static IP will cost a bit more because the ISP has to go through a couple of steps to set it up for you. But once you have the address, you now have a way for folks outside your network to connect with you.
(I’m also assuming that you use a router of some sort through which traffic flows out to the internet and that you aren’t using connection sharing or something like that.)
The next thing you need to do is have your new static IP address associated with the server on which you are hosting your website. You've probably already done that if your website works inside your network. However, you've associated a private ip (192.168.x.x, etc.) to your web server. That doesn't mean anything to folks on the outside because private IP addresses are just that - private - folks can't access them. (I won't get into VPN because that's a whole other topic.)
The way you associate your new static IP address to your web server is through some sort of dns application from your ISP. For example, we use TierraNet to manage our external DNS information. They have a web interface control panel that is very similar to the DNS interface for XServer. You can create CNAME records (aliases - other ways that folks can access your servers).
Basically you create an "A" (CNAME) record with a fully qualified domain name (e.g. webserver.myschool.org) and point it to your public IP address (XXX.XXX.XXX.XXX) which you just got from your ISP. It's going to take a while (24-48 hours) for this change to take effect. BTW, you can create as many “A” records as you want. For example mail.myschool.com and wiki.myschool.com could point to the same place.
You want to make sure that the fully qualified domain name you enter in the external dns utility matches the name you used when you created your internal dns records on your XServer.
OK...so now folks can get to your domain - but, remember, you have a private network IP scheme between them and you. You now have to tell your router that when web traffic arrives, allow it inside the network and direct it to your web server.
Let's say your public IP address is 205.100.112.50 and your web server is 192.168.0.5.
You have to create, in your router’s "Security Zone" (router companies call them different things) a couple of rules. Usually the first rule is: "Let everything inside the network get out to the web." You've probably already done that if folks inside the network can reach the internet.
You then have to tell the router to allow web traffic (port 80) into your network AND redirect that traffic to 192.168.0.5.
We use AdTran routers and they have a web interface which allows you to write "rules" affecting public and private traffic. Public is folks outside the network, private is folks inside.
AdTran calls them "Security Zones" and you modify those zones with policies.
So my "Policy" would say, in the above example, redirect traffic from my public IP (205.100.112.50) -> to my web server -> (192.168.0.5).
THEN you have to modify this policy with what AdTran calls "Traffic Selectors". You've said, OK, you can get in, but WHAT can get in?
The "Traffic Selector" is written to say: "Permit" "TCP" traffic from 205.100.112.50 only through Port 80. (That's the port that web traffic goes over. If you wanted a secure website, you'd add another traffic selector that opens port 443, for example.)
I'll tell you I'm no genius when it comes to this. I called AdTran and had them configure my router for me. I told them what I wanted done, they remoted into the router and configured it. But then I could go to the web interface and see what they did and then added rules later on when I wanted, for example, to get access to the network via Apple Remote Desktop or VPN into the network on my iPad.
I'd bet that your router has a maintenance agreement that includes this service and if it doesn't it should have.
I did find that I still had issues when I tried to set this up originally and it had to do with the ORDER of the policies. I can’t remember exactly what the issue was, but, effectively one of the policies highjacked traffic before the policy that I wanted got triggered. Simply moving them around in the list fixed that issue. So if you have this set up but still can’t access the site, check the order of your rules.
I don’t know if that helps or not, but I try to think about this stuff conceptually and then get someone to help me with the details. I work with this stuff so infrequently that I forgot how I did something 6 months or a year ago. I’m in the process of creating a wiki for the school which documents all this stuff, but that’s a major undertaking.
Cheers,
John

How to set up a great Photoshop machine

How to set up a great Photoshop machine
From the blog of John Nack, [former?*] Photoshop Principal Program Manager
At Photoshop World this week, performance testing lead Adam Jerugim
presented a performance guide with hardware recommendations and
information about the CS5 performance preferences. I’ve put his notes
in this post’s extended entry.
http://blogs.adobe.com/jnack/2010/09/how-to-set-up-a-great-photoshop-machine.html#more-271 2
Operating Systems: Mac OS 10.6.4 and Windows 7 64-bit
CPU: Intel Core i7/Xeon or AMD Phenom II/Opteron with 4 cores. More than 4 cores gives diminishing returns.
RAM: Enough to keep Efficiency readout at 100%. If Efficiency is low (<95%), adding RAM will provide biggest benefit. 4GB will cover most digital photography uses. 8GB leaves room for other apps and fits huge documents in RAM.
Video Card: Any modern card with at least 512MB VRAM; 1GB if doing heavy 3D work.
Disk: Use a separate disk for Photoshop scratch. If you spend a lot of time opening / saving large data files, another separate disk for data files will speed that up. Faster disks are better. RAID0 is faster. SSD is faster yet. RAID0 of SSDs is fastest but super expensive. If you have plenty of RAM (meaning your Efficiency readout is 95% or more), separate/faster disks for scratch provide minimal benefit. If Efficiency readout is low, a separate SSD for Photoshop scratch will be a big win. SSD boot volume will speed booting and app launch, but not Photoshop operations.
Memory Usage: this should be no higher than 70% on systems running 32bit Photoshop or with less than 4GB of total physical RAM. On systems with 8GB or more, use 70% if you plan on running other applications at the same time as PS, or higher (up to 90%) if you only plan on using PS on your system.
Efficiency %: can be found in the document window drop-down options. Operations fit in RAM when this 95% or greater.
History & Cache: if you work with small documents with lots of layers, start with the Tall and Thin button (which will set cache levels = 2, tile size = 128K/132K). If you work with large documents with few layers, try the Big and Flat button (which will set cache levels = 6, tile size = 1024K/1028K). Using more history states uses more scratch disk space. More history states may also use more RAM, particularly when running actions or scripts on large documents. If you see Efficiency drop below 95%, especially after running actions, try reducing history states or adding RAM.
Scratch Disks: a separate drive for Photoshop scratch disk will avoid slowdowns from Photoshop and the OS trying to access the disk at the same time. If your Efficiency number often drops below 95%, the gain can be large. Faster disks are better. A RAID0 array is faster, an SSD faster still. If using a RAID or SSD, try setting the Tile Size to 1024K – AMD CPUs prefer 132K / 1028K sizes, but 128K and especially 1024K are more efficient for RAID and SSD use regardless of CPU type.
GPU Settings: you can change GPU settings by clicking on the Advanced Settings button. For more more modern video cards there will be three options: Basic, Normal, Advanced. Changes to this setting will only take effect after PS restart, and would be worth experimenting with if painting performance is sluggish.

How to tell if RAID is working

I'm trying to set up a mirror set on our server. I used Disk Utility to create the array (selected the primary disk, chose the RAID tab, dragged the new disk in). It created a RAID slice and says it's online. HOwever, the "RAID set size" says ZeroKB and if I look at the second drive there is no data on it and the available disk space is being reported as the total size of the drive. Shouldn't it start copying the data automatically?? I'm totally new to this so any help will be greatly appreciated. Thanks!

In Disk Utility begin by selecting one drive or volume you wish to be a part of the new RAID set.
Click the RAID tab. Set the volume format and RAID type.
Then drag the disks or volumes that will be part of this RAID. In the case of RAID 1 (mirrored) you will need two disk or volumes of the same capacity. You must add both disks or volumes.
Warning: Creating a RAID will destroy the data on the drive so if you are creating this from a live server you must back up the machine prior to creating a RAID. Also, you can not create a RAID that contains the server boot drive while booted from that drive, you can only do it booted from the install disk or from another volume.
You can however use a pair of separate disks as RAID members while booted from the server boot drive.
Here is how I set up our RAID. Boot from install disc, select Disk Utility from install menu, create RAID 1 using both internal 500Gb drives of the Mac Mini Server. Restarted the machine and did a new install of the server OS to the now bare RAID 1 volume.

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

How to set up a basic file sharing server for my small architectural business?

I have no idea if I have posted in the correct area as this is my first forum post within the apple support community!
I have been using a 21.5" imac running 10.6.8 for the past 5 years to run my small home based architectural design business. I have been using the internal hard drive & backing up the necessary data to a simple usb external hard drive. I am now looking to firstly purchase a new imac 27" retina and purchase new autocad lt 2015 for mac software. I am looking to have another imac (my old mac) running in conjunction with the new mac. I want both macs to be able to access the same data and am slightly unsure what is the best way to achieve this.....As my old mac is currently only running snow leopard and an old version of autocad for mac 2011 it wont run on any more recent OS. Essentially i believe I have 2 main options with this.... (1) I Accept that I have to purchase 2 no. autocad lt 2015 licences @ a cost of £2300. Or option (2), I only run autocad on the new mac as this will be the primary station and the old mac used for primarily for admin & accounts. I have also recently discovered that it is possible to rent autocad licences for £300p/a which may also be another option (3)!
I previously had a problem where my hard drive failed on my mac & lost all data on the internal hard drive, luckily I had been backing up all data regularly to my external hard drive and now loss occurred! Obviously with any new system I want to ensure that my data is safe!
I currently utilise about 250GB of data for business operations but this will obviously grow with time.
In the future I would like to have the option of potentially being able to access the network data remotely via macbook pro whilst abroad although at this stage this really isnt my primary objective. Although I believe I could achieve this through apple remote desktop.
I suppose I should provide some information with regard to the required speed of the system...I regularly open 50-100 photos at the same time totalling around 250-500MB. I would like the system to be able to handle this fairly easily.
I have been trawling through forums and to be honest they are totally confusing me. I have also spent time on the phone to the apple business team and have also discussed my objectives with a member of the apple team in store.
There have been various options advised to me and I really do not know which is the most appropriate route forward.
1 - Using a mac mini as the file server and linking the 2 mac devices to this and backing up the mac mini to an external hard drive to ensure no loss of data.
2 - Using a time capsule as a file server and linking the 2 mac devices to this and backing up the TC to an external hard drive to ensure no loss of data.
3 - Using the new mac hard drive and linking the 2 macs via thunderbolt (old mac does not have thunderbolt and so I guess I would need another new mac?!) and then backing up the data to a time capsule.
4 - Using a RAID based server and linking the 2 no. macs.
Sorry to ramble but any advice really would be greatly received!

Hi sblemings,
Welcome to the community.
I think with your scenario you should ask yourself, how complicated do you want the setup to be and how much time would you have to be able to resolve an issue should one occur with this setup.
All the options that have been advised would work but they come with complexity and therefore time.
1 - Using a mac mini as the file server and linking the 2 mac devices to this and backing up the mac mini to an external hard drive to ensure no loss of data.
2 - Using a time capsule as a file server and linking the 2 mac devices to this and backing up the TC to an external hard drive to ensure no loss of data.
3 - Using the new mac hard drive and linking the 2 macs via thunderbolt (old mac does not have thunderbolt and so I guess I would need another new mac?!) and then backing up the data to a time capsule.
4 - Using a RAID based server and linking the 2 no. macs.
Sorry to ramble but any advice really would be greatly received!
option 1
Would be a way to achieve what you want, it would centralise your files and you would only need to backup your file server (as long as all the files you wanted backed up were on it). This could be achieved either using the client and sharing various folders or using Server which would give you more options than you would possibly need.
option 2
This is exactly like option 1 except that you wouldn't have to administer another mac however you may limit any future growth.
option 3
This option I probably wouldn't pick, you could achieve this with firewire and use a firewire to thunderbolt adapter (saves you having to buy a new iMac)
option 4
This option would, depending on your RAID level, give you disk redundancy but remember you would still need to back this up, as RAID is NOT a backup solution.
I would also ask is there a pressing need to keep the old iMac in service and complicating things by having a server / NAS? Could you not just transfer all your information over to this and continue with the one backup? I would say that doing it this was would be the simplest way of achieving what you want from what I can take from your question.
As for remotely accessing your data, if you have the right hardware the way to achieve this would be to use a VPN and connect back to your data. However a potentially easier way for you ,would be to use a service like logmein or teamviewer to connect back.
Hope this helps, and by all means any questions please ask.

How to set up a basic file sharing server for my small architectural business?

Setting up RAID 0 and scratch disk from blank drives?

Folks,
Howdy again from NC. I've been setting up an AMD Phenom II 955 to handle PPro CS5 as well as possible, within limits. I built four of these machines for my math class, and am going to give CS5 a go on one of them before caving in and migrating my Production Premium to an i7/X58 platform. Maybe I'll get lucky and find this computer works acceptably with PPro, especially if I transcode my T2i AVCHD footage (likely Neoscene).
I put three new disks into my build yesterday and would like some pointers on setting them up, if I may ask. I have read through a number of posts on this, but don't find direct answers, unfortunately. I've never set up a RAID and want to get it right.
I have two Caviar Black drives for my RAID and a Hitachi Deskstar for my scratch disk. The Blacks are new out of the pack and the Hitachi has had zeros written to the drive. How to begin?
Anticipated issues:
* Do I need to format the drives in a certain way? I had planned on going into Disk Management and setting up a volume on each as my first move. Right now, they aren't even recognized under My Computer. Under Disk Management, all three show as unallocated.
From memory, I right click in the unallocated space and select an option for setting up the volume. Prior to this I only used straight-up drives, no RAID, and after writing zeros to a drive selected "New Simple Volume". It seems to me this is the move to make on the single scratch disk.
But how about the two RAIDed drives? We also have options to set up as "New Striped Volume" or "New Spanned Volume". If the answer is to set as as "New Striped Volume" for the RAID 0 I have planned, do I do this before or after installing the RAID software?
* My documentation for setting up the RAID on my motherboard doesn't indicate when to change my BIOS setting for the two SATA channels from IDE to RAID. Should I do this before or after running the software to set up the RAID? Do I need to go into the software setup with the two SATA channels already configured as RAID?
Right now, all SATA channels are configured as IDE.
* After getting my disks set up, I'd like to optimize my system for editing (turning off unwanted features, etc.). I've been looking all over for a link to an outside site I had bookmarked from a prior post, but lost it on re-install. Anyone recall what the favored link was? It started as a long page of instructions in simple typeface.
In the end, my disks are as follows (unless someone makes a case to use them differently):
OS/Programs - 1TB Caviar Green. Yes, I know the deal on green drives, but I needed to use this drive somewhere. I figured using it as the OS drive would be the best spot for the slowest drive. Maybe I botched this and should have used the following drive for the OS? I had transfer rates in mind and thought the Scratch drive should be faster?
Scratch - 750GB Deskstar 7K100 series. This drive was tops 18 months back when I bought it.
RAID 0 - Two 640GB Caviar Blacks (32 meg cache, twin processors). A bit older in the Black lineup, but the drive charts show them working quickly.
To ask one dumb last question, which will really show my newbieness, I use the scratch drive for page files (right? and what else?) and the RAID for holding any media to be worked upon and for encoding the final project?
I've been reading on this forum for over a month and am amazed that as I have the drives for a RAID, I can't find good links to tell me what to do. I know I am asking redundant questions here but have already spent two hours with the search engine and am only getting tangential anwers (ha! math joke).
Sorry to be asking such newbie questions all over again, but my luck with the search engine hasn't been so good of late. Maybe Bill's idea of creating a sticky section for common questions is a good idea.

about 75-80% of the systems we ship, ship with this config (others would be bigger arrays or no array)
1)OS
2) project drive 2 x raid 0
3) render to/export drive 2 x raid 0
4) back up (pick your poison)
while i cant speak to the older WDs (we have not used them for 3-4 yrs until now)
i can tell you with Seagate and now WD we have not seen the issue that applies to this inRaid 0
we are aware of the timeout issue this happens with controller cards and seagate or WD with large raid 5/6
simple answer use enterprise drives for raid 5/6
if you look at all the external raid resellers Sonnet etc they all use enterprise drives (mostly seagate)
so do we for large raids.
(drobo does not so buyer beware (green), we like to sell drobo without drives in it and use ours)
again BACK UP do not assume your raid 3/5/6/10/1 whatever is bullet proof, trust me its not
so even if you have a loss it should be at best nominal
something i dont think i have seen mentioned enough either
the single most common cause of drive failure (or any component failure) is Dirty Power!
dirty power can be spikes but are usually brown outs (very common in large older cities) or even low voltage coming into the home/office
this is the most common.
rather than a clean 120v you could see it as low as 105v
the other is being on a circuit with a large appliance.
ever see your lilghts flicker when the AC kicks on?
buy a good inline filter UPS. add 20% MORE wattage than your power supply
dont forget to add accessories LCDs, Audio interfaces, speakers/studio monitors etc.

How to set up "find my mac"

Hello,
I have an iMac with OS X 10.8.4, and I try to activate "find my mac" option but it says: Recovery partition required >> Some configuration, such as a software or hardware RAID, do not support a recovery partition and can't be used with Find My Mac.
Can anyone tell me step by step how to set up this partition?, then I can activate the Find My Mac option.
Thank you in advance!
signos

I recommend you post your question as "How to restore recovery partition" (or something similar) over in the OS X Mountain Lion forum: https://discussions.apple.com/community/mac_os/os_x_mountain_lion. I believe all you have to do is reinstall Mountain Lion on top of your current installation but they would have more expertise on this.

Set up raid on A78M-E45

How do I set up RAID on A78M-E45 with AMD A4-4020 Richland processor. I can't find anything in the manual or online here.
Thanks.

Re: Setting up RAID with A78M-45
I had the same question and after much searching this is what I did.
- Download the RAID driver from the MSI web site
- Set the BIOS to "RAID"
- Boot from the Windows Install disk. In my case this was 8.1 x64 and at the Disk & Partition screen the Installation reported it was needing a driver.
- Browse to the location with the downloaded RAID driver, and the Windows installation continued
- Once Windows was installed I downloaded and installed the "Chipset drivers" for the motherboard. This required a re-boot
- After the reboot on my desktop there was a new icon "AMD RAIDXpert 2". Open the utility and login (admin admin).
- From here you can configure RAID on your remaining drives. I downloaded the .pdf the AMD RAIDXpert 2 utility as it looks like I need to read a bit before configuring my drives.
Hope this is helpful to anyone else needing to do the same thing.

Portege S100: How to change the RAID in the BIOS

Changing the BIOS setting for Portege S100 from JBOD to RAID0, I hit space on Exectute Creation and enter the string key in the manual and press "enter".
The settings then return to existing settings and not the new RAID0 setting I selected.
I have been at this most of the day / evening looking at various posts, but I can see nothing wrong with the details entered.
It is the same as recorded in this link:-
[How to Change the RAID configuration|http://aps2.toshiba-tro.de/kb0/TSB6901K60006R01.htm]
I am now at the end of my tether, I only wanted to install new WD HDD and do fresh install of XP Pro, is that too much to ask?

Maybe its a silly question but; did you install the second HDD in the Ultra Slim Bay?
The RAID feature is ONLY available when a second HDDD is installed in the Ultra Slim Bay.
If the second HDD has been inserted then you could change the RAID in Windows OS.
There should be a Toshiba RAID Console.
You can use this console to create or manage a RAID array.
To start the utility click Start, point to All Programs, point to Toshiba, point to RIAD and click RAID console.
Its possible to change RAID1 (mirroring) from a non-RAID configuration (default).
But note; when RAID1 is set, you cannot change your settings unless you completely restore your preinstalled software.
