Building an editing raid setup with an areca 1220 (8 port)

and here's goes yet another "what should i do raid-wise" question:
gonna build another editing station using some extra parts i have laying around. board is an asus x58 with a intel 980, video will be a nvidia 470. i found my old areca 1220 which i know is a little long in the tooth but would be nice to get some more use out of.
doing a little research i found some articles on what kind of speeds im looking at with it. its obviously not quite what a shiny new card would give me but im hoping with a faster pc and faster drives (articles are from 2007) it'll give decent performance for what i need.

http://www.tomshardware.com/reviews/RAID-SCALING-CHARTS,1662.html (raid 5,6)
ill buy all new drives for this machine (os, media, etc...). i know harm likes his raid 3 thing and im hoping he pops in with his expertise. so my question is how should i go about my complete disk setup from scratch here? type of disks? how many? which raid setup?
My budget is $1000 for the disks. also i mostly edit hd from my mark iii. im using the ml raw hack for about half my shots (and growing). pp cs6, ae cs6, cinema 4d r14 are my progs, though im a cc subscriber and will be integrating the new cc progs into my workflow over the next month or 2 as they work out the bugs/kinks. TIA

With 8 ports available your choices are somewhat limited, but then your budget for the drives is adequate.
You did not mention how much storage space you need, so I will assume 6 or 12 TB net space is enough for your purposes.
If 6 TB is enough, you could look at Seagate Constellation ES 1 TB disks and keep the rest of your budget for the future, if you need 12 TB you could look at HGST Ultrastar or Seagate Constellation 2 TB disks. I would only suggest enterprise drives.
With 8 ports I would configure them as 7 x raid3 or raid5 plus one hot-spare, giving you a net capacity of 6 disks, protection against failure of two disks and a sustained transfer rate of around 0.85 x (N - 1) x T = 0.85 x (7 - 1) x 150 = 765 MB/s. My preference is raid3, but you already know that.
The advantage of this setup is you have double protection in case of disk failure, you have a very high transfer rate and it is easy to administer. Using two arrays reduces performance, reduces protection and is somewhat more cumbersome to administer.

Raid setup with g-tech raid

hello there.
bit confused by this raid business. Just got a 4tb g-tech raid system which has 2 drives of 2tb each.
It shows as one disk in finder. DO i only have to set 'RAID Type' to 'Mirrored RAID set' in disk utility? Do i need to make 2 partitions first?!
its just that it still shows 4tb available and i was presuming it would say 2tb?
any clarification welcome..! Dan

I don't know much about these, but since nobody who does has happened along . . .
There are different kinds of RAID. The two most common are:
A +Concatenated RAID Set+ (or RAID-0) combines multiple disks into one volume; the size is the total of all the disks in the set. It sounds like that's how yours is set up.
A +Mirrored RAID Set+ (often called RAID-1) keeps identical copies on each disk, so if one fails, you don't lose any data, and can keep running. The size is the size of the smallest disk in the set. It sounds like that's what you want.
If all the drives are in one enclosure, they're usually configured by hardware switches on the controller, or possibly software options you can set via an app that comes with the set.
Check with the maker (or instructions that came with the system) for setup information.

Ghost a raid setup with 1 floppy

I had used Driveimage 7.0 but it would no longer work, I found this image program:
http://www.terabyteunlimited.com/
look for Image for DOS and Image for Windows.
It all fits on 1 bootable floppy that it helps you make!
Easy to use, no need to load your raid drivers to restore, Makes images inside windows,
Does eveything Driveimage did plus it is faster. I have restored my raid drive many time with this.
This software is worth paying for ;] That why I did!

Dont need the raid drivers to make a image or restore one using image for dos.
thats whats so simple about the program. nice and clean no muss no fuss.
no fancy menus, just create or restore, lets me use all my drives, usb drives,dvd\cd
all with one floppy! restores my raid drives twice as fast as driveimage.
the menu is simple, just choose your drives and go!

P35 Neo 2 RAID setup

Hey Everyone;
Just picked up this motherboard today and i'm trying to get a couple of 150GB Raptor drives running in RAID 0.
I don't get the intel storage matrix RAID configuration tool on POST like the manual says i need to get. So needless, to say, when i go to install windows XP (yes, i still don't really want to install Vista) I can see the drives just fine but i can't create a RAID setup with them.
I have gone through the BIOS settings, but perhaps i'm missing something in there. Can anyone detail what i need to do to get this running?

I guess that's the only reason, but glad you found it

K8N Master2-Far, Single 144 Opteron & Areca 1220

Hi
I would appreciate feedback please. I have already built a Gigabyte based Samba server using the Areca 1120 (PCI-X) RAID controller & 2 x Opterons.
For reasons too complicated to explain, I now want to build much the same thing but using a single 144 Opteron and the Areca 1220 (PCI-E) RAID Controller. This is JUST a Samba file server, it doesn't do games, isn't used for browsing the web, OpenOffice, etc. and sadly, will not be 'Folding'.
I was on the point on ordering a K8N Master2-Far, Areca, ECC RAM, PSU (dual-line !) etc. when I read some of the postings on this board. Now, I'm not so sure . . .
There appear to be a number of 'issues' with this MoBo. If you have built a system based on it, how has it gone ? What BIOS version are you using ? What PSU are you using ? I would be particularly interested to hear from anyone who has experience with it and with the Areca 1220.
Many thanks in advance.

Mac Pro RAID 0 setup with bootcamp

I'm about to take the plunge and buy a Mac Pro as soon as I get the money (or credit) to. There have been things here and there that have turned me off but I found ways around some concerns, but this one I haven't been able to find.
I am a musician and want to utilize raw power that Mac does so well with. But unfortunately my DAW of choice doesn't support OS X. I hate Vista, I never upgraded, I stayed with XP but have been willing to change to OS X with XP as well, to get the best of both worlds. Then i find my DAW doesn't support XP 64 bit so i am going to have to use Vista 64-bit (bummer).
What I haven't been able to figure out is if it is possible to run a RAID 0 of the windows OS and all its data. The Mac Pro RAID card doesn't support any Windows OS so i am wondering if there is anyway possible to get the Windows OS in RAID, any good hardware or software that will accomplish this. Like if i get the Mac Pro RAID cad, is there a good software or hardware RAID that will allow me to install windows in a RAID 0 configuration?
If its possible I would have no reasons to not move over, but I really need to have my RAID setup in windows since I am using latency sensitive disk streaming programs that need to stream files in the GBs
Also could I just opt out for the Mac Pro Card and get a generic RAID card that supports both Windows and OS X? And if so any recommendations?

MacWorld SanFran in a couple weeks is when Apple traditionally would use to announce some of the new products for the next year (Snow, Mac Pro '09, new iMac, etc).
Apple is not very upgradeable. It would cost me more to upgrade the cpu than buy new (though can get a good $$ on my system - in part because it runs the prior version of OS X 10.4 "Tiger". New systems will only run the current/latest OS, you won't be able to run Leopard if a system comes with Snow. The graphic choices and upgrades can be lame. It is almost a closed box.)
I've talked to people that were into audio that used Fibre Channel in part due to low latency, increased queue depth (which is one area SATA has never implemented, 32 vs 256 I/O per sec).

Shanghai’s 16 cores outperformed Dunnington’s 24 cores (or 48 if Hyper-Threading was used) by 6.5% or 8.8% depending on whether or not IBM or Dell’s chipset was used. But if we normalize that out per core, Shanghai outperforms by 59.8% (per core) or 63.2%. That is unbelievable!

Udev/dmraid not picking up all partitions of a fake RAID setup! [EDIT]

Hey all. I've been having a problem with my RAID setup in Arch. At first Arch wasn't picking up a partition on one of my arrays, (a single large NTFS partition on a 2TB array between two 1TB drives) but after re-creating the RAID array in the Intel Storage Manager I have a different problem. Arch now find the single large partition, but now /dev/mapper isn't populated with the other two partitions on the other array that my operating systems are on (Arch and Windows), when it used to just fine! The only thing I changed was re-creating the partition table on the other array, so I don't know what's going on.
Upon trying to boot, GRUB comes back with the error described on the wiki: https://wiki.archlinux.org/index.php/In … oot_device
However I can't boot into the fallback image either! This means that I can't apply the fix as described in the wiki.
I'm starting to think there is a limitation in Arch where it can only handle a certain number of mapper devices (seems to be 3), or maybe it only detects the partitions on the first detected array? Now that I recreated the partition table on the larger array, it seems like that's the array that's detected first in both a GParted live session and Arch. But in a live GParted session, /dev/mapper was fully populated with all of my disks and partitions... so why is it that Arch can only find the partitions on one of the RAID arrays?
If you guys need any additional information just let me know... I really want to get my Arch setup up and working so I don't have to use Windows all that often (only games that don't work well in Wine).
EDIT: Changed post and title to reflect new problem after recreating the 2TB array

Does anyone know if I can damage my arch install by using mkinitcpio through a Debian live-cd? I'm going to try and use one to remake my initrd by chrooting using this guide: https://wiki.archlinux.org/index.php/In … oot_device
Basically the commands I'm looking to execute would be this:
# mount /dev/mapper/isw_ArchRaidPartition /mnt/
# mount -o bind /dev /mnt/dev
# mount -t proc none /mnt/proc
# mount -t sysfs none /mnt/sys
# chroot /mnt /bin/bash
(edit mkinitcpio.conf according to wiki, inserting the "sleep" hook)
# mkinitcpio -p 3.0-arch
So my question is would using the commands from a debian live distro work? I have to use debain since arch live-installs don't detect my arch raid partition, like how I described above. I also can't boot into fallback.

Building a Raid-0 with two out of four internal drives?

Hello everyone
I have four drives in my MacPro:
1) OS+Apps
2) Virtualization
3) iTunes
4) empty
My iTunes library fills drive 3 and I am close to having a full drive.
I would like to 'span' my iTunes library over to drive 4 and was thinking about building a Raid-0 on drives 3) and 4).
Can I do this without any additonal software and hardware?
Do I simply do that in Disk Utility?
Can you foresee any limitations to that setup (except for fault tolerance)?
I assume performance is also sufficient as after all it is only for iTunes.
I am not worried about drive crashes as I can back-up the spanned drives externally
Any thoughts?
Thanks in advance

Quick follow-up information from the disk utility help menu:
"Using several disks as a single volume with a concatenated RAID set
If you need to set up two or more disks or volumes to work together as a single, large volume, you can create a concatenated RAID set. You can even increase the size of a concatenated disk set after it's been created by dragging more disks to it in Disk Utility. This RAID set is helpful if you have a file, such as a database, that's larger than any of the disks you have. Or you may need to create a mirrored or striped RAID set with one large disk and two smaller disks.
If you booted your computer from a disk that has multiple partitions, you cannot create a RAID set that contains partitions from your boot disk. To create a RAID disk that contains partitions from that disk, you must boot your computer from another disk or the Mac OS X Install disk first.
You cannot remove individual disks from a concatenated disk set."
So it seems I can add disks whenever I want but once added I can't remove them...

Trying to setup RAID 1 with new SATA drives on xserve 2009 model

Trying to setup RAID 1 with new SATA drives on xserve 2009 model
I have an Xserve rack mount model Xserve 2.26 Quad Core (EMC# 2279) with an Apple RAID card, 24GB RAM (running 10.9 Server software)
Purchased two Western Digital 1TB SATA III 7200 RPM 64MB Cache Black WD1003FZEX drives
It came with three 160GB SATA drives. I'm leaving one of the original 160GB drives for the OS, but I want to replace the 2 other drives and set it up with RAID 1 (mirrored). I bought 2 brand new Western Digital 1TB SATA drives and formatted them on another Mac through Disk Utility with Mac OS Extended (Journaled) formatting. I then placed the new drives in the Xserve and booted it up. After I login it immediately gives me 2 error windows saying...
"Apple RAID Card
The Apple RAID Card installed in your system requires your attention."
It has two buttons underneath this message allowing me to either select 'Ignore' or 'Open RAID Utility'
I've tried to RAID the drives the Disk Utility and through the RAID Utility with no success.
I have both drives mounted on the desktop, as separate drives, but I really need to set these up as a RAID 1.
I've been reading other forums, where others have been able to get this to work by using a jumper on certain pins (5 & 6)of the drive to back down the transfer rate to 1.5 Gb per second. I tried that and it didn't work for me. Maybe I used the wrong pins -- I just don't know. I'm also wondering if there is some Apple firmware that is required on these drives? I'm asking for help from anyone who has gone through this same issue. Thanks in advance.

UPDATE -- I had an issue with the RAID card battery, it was dead and I have since replaced it. But I am still unable to setup the RAID 1 drive configuration. Does anyone know if it has something to do with the faster transfer rates on these new drives. Maybe they need to be clocked down with certain jumper settings on these Western Digital drives? Or am I fighting a losing battle because these drives don't have Apple firmware? Any help would be appreciated. Thanks.

Pros and cons to JBOD/N-RAID setup on MacBook Pro with two internal SSDs

First, to clarify, in this case, I mean the term "JBOD/N-RAID" to refer to a concatenated or spanning set of drives as supported by OS X and Disk Utility.
I've got an original Apple-installed 120GB 3G (3Gb/s) SSD which I'll be moving into the optical bay using an OWC "Data Doubler" and swapping a new 240GB OWC Mercury Electra 6G (6Gb/s) SSD into the main drive bay.
My goal is to avoid having two separate volumes.
Understand that a RAID 0 array would essentially only perform as well as the slowest drive in the array (the 3G SSD in this case), if it would even work at all given the two drives are not identical in make and capacity.
I've read that a JBOD/N-RAID array isn't subject to the "same make and capacity" constraints. But how does this setup perform?
Would the speed of the 6G be hobbled, slowed down to the 3G's speed (or worse?), if I were to set up the two SSDs as a JBOD/N-RAID array?
Is this even a recommended idea - that is, paying for the convenience of having one virtual volume by adding the complexity (and risks?) of a JBOD / N-RAID setup?

I am following your advice and attempting to install Bonjour. I wasn't sure where to install it so I am following the VMWare Knowledge Base #1003814: Sharing a printer with a Windows virtual machine using Apple Bonjour.

Steps to Setup a Raid 1 with a clean install of 10.5.2 and 2 new HD's

What are the steps I need to take to setup a RAID 1 with a clean install of 10.5.2 on a G5 tower with 2.0 Ghz dual processors.
(1) Any restrictions on the size or brand of the 2 drives I will install to replace the old drives? Are 500 GB, 750 GB or 1TB Seagate SATA drives ok for this appilcation?
(2) What format do I need for these drives and will Leopard take care of that automatically upon installation?
(3) Do I need a RAID controller card?
(4) Do I set up the RAID 1 when installing Leopard or after it is installed?
Thanks Ron

Creating RAIDs is discussed in Disk Utility Help from the DU Help menu. If you plan to install OS X on the RAID then the RAID must be set up before installing OS X. DU can be launched from within the OS X installer.
There are no current restrictions. In general use drives of the same make and model for best performance.
Drives must be partitioned using GUID partition mapping and formatted Mac OS Extended, Journaled. Partitioning and formatting are also discussed in Disk Utility Help.
You do not need a RAID card as you can create a software RAID using Disk Utility.

Having probs with a raid setup on K8N Neo2

Hey all i have a MSI K8N Neo 2 Platinum [MS-7025 ver 1] mobo with 2 WD 36 gig Raptors ...i am having one hell of a time settin up my raid system
after i load my drivers after the f6 prompt and follow the instructions in my windows setup it shows as me having 2 drives rather then one...and if i try t install, it gives me a blue error screen..i forget the actuall error msg but it is along the lines of a general hardware failure...Both harddrives are good as i have installed os's on both drives seperatly and i have run raid setups on my last 5 systems and never encoutered any probs..I have replaced my sata cables,changed power connections,2 different xp discs,new sata and raid drivers,and updated the bios but with no success.If anyone has a link or a similar experience with this can u plz help me out. i have the 1.4 bios and like i said earlier all new sata cables so i think i have all the basics covered.i love this mobo's features but if i can't get my raid goin its not much good to me so any help would be appreciated
Thx

Here is what I meant:
Unplug the power connector from one of the two raptors so that your system "sees" just one HDD.
Install Windows with just that drive being visible (maybe you have already done that I am not sure).
After Windows is up and running that way, then shut down the computer, plug the power back into the second drive,
set up your raid arry in BIOS and then boot into Windows. You should then see Windows detect the raid and ask you to install the drivers for it.
I think we are saying the same thing but not sure.

Extremely Unhappy with FM2-A85XA-G65 Raid setup

I was going to setup a Raid5 array on my new FM2-A85XA-G65 but it seems to really be an unusable mess. I have updated to latest 1.7 Bios and got no improvement. I am loading Windows Server 2012 Essentials on this machine so UEFI is a must and there for Legacy Raid is out. There was supposed to be an improved way to set up an UEFI Raid 5 array in this new BIOS but I don't see squat. Setting the Legacy Raid seems to be the only way to get into the board's Raid setup but as I said that is a none starter. I had read elsewhere that the 1.7 Bios allowed UEFI Raid setup from the Bios menus (which is how it should be with a board boasting easy graphical UEFI setup) but there appears to be no such thing.
Extremely unhappy and thinking of returning this board. I've currently setup the Raid5 array using the Windows Server 2012 and it seems to work fine but I assume the motherboard based Raid would have significantly better performance, correct?
How much better performance should the motherboard based Raid be, and has anyone got Windows 2012 Server to load on Legacy Raid?
Is anyone using AMD Raid Expert with this Motherboard's native Raid setup?
Is the new Storage Spaces feature in Windows Server 2012 a better option than Raid5?

Quote
Is there any other way to fix it?
Not without a Trinity cpu. Alternatively ask reseller or MSI to flash it for you.
Quote
For example: can I get an old FM1 CPU from a friend to test it?
Of course not. You need a FM2 cpu. FM2 and 1 aren't compatible.
Quote
And what can you tell me about the memory?
Will it work on this board?
Those sticks are ment for Intel systems (http://www.kingston.com/datasheets/KHX21C11T2K2_8X.pdf) but they will most likely work with safe settings. Don't expect them to go anywhere near 2133. First that would be oc as your cpu's mem controller supports just up to 1866. Secondly because the ram is meant for Intel system's it might even with oc not work at the same settings/speeds it would work on Intel systems it is specified for.

Questions on Marvell vs. intel Raid setup for new build

I’m getting ready to do my first build this weekend, and had some questions on the Asus p9x79pro motherboard’s raid controllers. They are:
What is the difference between the Marvell controller and the intel software controller?
Why would I use one over the other?
Do the Marvell raid controllers need to be pre-installed using the F6 method, same as the intel raid controllers?
Here is my planned drive arrangement, feedback appreciated.

(1) Western Digital WD Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive - media cache & renders
(1) WB Black 32mb cache 3.0 Sata - Exports and non video file storage
Asus BD burner on 3gb port
Thanks

What is the difference between the Marvell controller and the intel software controller?
I haven't tested it, but rumors are that Intel is marginally faster than Marvell.
Why would I use one over the other?
It depends on the number of ports in your system. That can be motherboard dependent.
Do the Marvell raid controllers need to be pre-installed using the F6 method, same as the intel raid controllers?
No. You can define a raid after you installed your OS by simply going into the BIOS.
On my motherboard, I have 2 Intel SATA 6 G ports and 2 Marvell SATA 6 G ports. The rest are SATA 3 G.
If that is the same in your case, I would do the following:
Crucial M4 on Intel SATA 6G
WD Black on Intel SATA 6G
2 x WD Black/64 on Marvell SATA 6G in raid0
WD Black/32 on Intel SATA 3G
DVD/BDR on Intel SATA 3G
one SATA 3G for eSATA connection.

Backup Raid Setup

Hello Everyone,
Happy New Year
I am looking for a Backup device for my Main Editing Suite, at the moment I am runing a Areca 1680ix 16 port with internal drives. I am looking for an exernal setup so I can back up my main editing suite and take away for security.
options:
1: use external out from current Areca to a enclosue using multilane cable, (is this possible even though i have 16 ports used already)
2: buy a new raid card with 2x external ports to control 8 bay enclosure or more
anyother ideas,
anyone had experience with Sonnet Fusion D800Raid it uses a Atto Raid Card, this model is a few years old now. not sure if suitable, as I have a freind who no longer requires one as he has upgraded and offered it to me.
thanks
Baz

Baz,
Have you considered a QNAP or Thecus NAS over iSCSI? There are models with 7 or 8 internal disks and for backup they are quite suitable.
Have a look at: http://tweakers.net/pricewatch/cat/685/nas-behuizingen.html#filter:ZY5LC8IwEIT_y5xzaPpQ2h9 Q8CAIehMPNVlhIX2wiQ8o_e8mak-eltlvZpgZV-kGu7MezRl1WUFB643GReHG4sNB2NCJe9p3LzTD3bk_wMMKRrEkL ZOzaPBgevpYNyXjx5QpeDPKt6paxUrIkQlkjxOZ35xCx3heFWmMj--WXSCJaEZZZ-n0KYxttPWpEzrHsixv
