RAID configuration with 3 HDs

Hi everyone,
I have a Mac Mini with Mac OS X Server. I am figuring out if it is possible to setup RAID with 3 hard disks.
In the Mac Mini there are 2 HDs of 500GB each. I have an external HD of 1TB connected through USB. I was thinking to make one striped disk of the two internal ones and then setup a mirrored one with the one striped and the external one.
So that I have for Mac OS X one hard drive of 1 TB (RAID).
Is this possible? I know I could just try it out, but my server is operational and if it doesn't work I have to setup it all over again without RAID.
Thanks for the reply's.

Hi
Yes this is entirely possible. Whether it's advisable is another question? If this was the main production server with all services enabled and a company's business depending on it I would not do it. Only my opinion though and seeing as it's your server, you do what you want. If this is going to be a lightly used server why not and give it a go?
Most of us who deal with servers regularly would not (a) use externally attached drives as part of a RAID Set because of latency and possible accidental disconnects and (b) not use USB. If you have to use an externally attached drive firewire would be better (preferable FW800).
If your server is currently operational you could target disk mode it to another mac (over fw800) use Disk Utility to create a .dmg of it. Or if you like CarbonCopyCloner, SuperDuper! or anything else you may have in your 'kitbag'. Once you've done that you can then save this .dmg to another externally attached drive. Set up the MacMini Server's internal drives as a RAID 0. Attach the external 1TB drive and configure the RAID 1. Restore the saved .dmg back to the newly set up RAID. When done disconnect from Target Disk Mode and reboot the server.
Hopefully you should be up and running with everything as it was before but with the desired RAID configuration you want.

Cost of SATA HDs ordered with S10? RAID configuration cost?

I'm considering buying an S10. I notice there is a charge for setting up the RAID configuration.
Is that just a "service charge"? I can change the RAID configuration later if I need to do so correct?
Also I note that a 500Gb 7200 RPM SATA drive lists at $205. At NewEgg for example the 500Gb 7200RPM units rated at 3Gb/s transfer speed are $60 - $90 each depending on details (cache size etc...). Am I missing something that causes the ones shipped with the system to be so much more expensive?
Thanks,
Jim
Solved!
Go to Solution.

mounting brackets will be included in the S10. there will be blank, plastic "dummy" drives installed in any unpopulated drive bay to help with air velocity. attached to these dummy drives will be the drive caddies that you need to install a drive.
RAID 5 requires all five drives to be the same or larger than the smallest drive size in the array. if you install a 1TB drive into a RAID 5 array comprised of three 500GB drives then only 500GB of the 1TB drive will be used. otherwise, there wouldn't be any redundancy on the second half of the 1TB drive. hopefully that explanation makes sense.

Is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

A Fusion Drive is not a RAID; it's a CoreStorage logical volume group. While it's technically possible to do as you suggest, there would be little or no benefit from it.

HP ProLiant ML110 G7 Intel Xeon E3-1220 RAID 1 with hot swap configuration

Dear All;
Am going to purchase 'HP ProLiant ML110 G7 Intel Xeon E3-1220' server partnumber '470065-591'. I want to know little more about its RAID controller. The above mensioned server having only two 500GB HDD. I want to configure RAID 1 on it and i want to add one more HDD 'HP 500GB 3G SATA 7.2K 3.5in MDL HDD' as hot swap for the RAID 1. here are my questions
1) it support RAID 1
i checked on few blogs. then i confirm I can configure RAID 10 with two HDD. so it will work same as RAID 1.
2) it will suport hot swap
actually first time am going to install RAID. Thats why am asking these questions.

Hi:
I recommend you also post your question in the HP Business Support Forum -- ML Servers section.

Are the Mac Mini Servers setup in a Raid configuration?

Are the new mini servers set up in a raid configuration?

Out of the box the mini comes without Raid. You have two identical HDs of 500Gb.
I have just set it up as Raid1. You can't do this when you use the startup disk from the mini. And as you don't have a Superdrive ... you need to be creative. You need another Mac with Firewire.
Step 1: Start the Mini in Target Mode. Press the T during start. In a few seconds the firewire logo will appear on your screen.
Step 2: Go to your second Mac. Connect the firewire cable between second Mac and Mini.
Step 3: On the second Mac start the disc utility. The two identical drives on your mini will show. Create a new Raid set (mirrored = Raid 1). Include both drives. Confirm the warning that all data on the mini will be lost.
Step 4: Make sure your second Mac has CD/ DVD sharing option installed. This is tou use the superdrive to install OS X Server on the mini.
Step 5: Shutdown both Macs
Step 6: Start your second Mac in target mode. Make sure the firewire cable is still connected.
Step 7: Start the Mini with the option key pressed.
Step 8: Insert the OS X Server install disc in your second Mac.
Step 9: wait till the drive logo apears om the Mini. Continue the install. Will take about an hour.
Good luck

RAID configurations

Hi!
I'm planning install oracle vm in a server with 4 HDs (300 GB each one), and I want to use some RAID configuration like RAID 5. How can I configure this setting while installing oracle vm server? What is the moment to do this? Is it automatic and don't I have to do anything?

Hi, if I remember well, you should continue until you get to the partitioning.
When you are prompted to do so, choose to "review the partitioning layout".
At that point you should see a "raid" button.
I'm not sure that's what you're looking for, as I have external storage I have never used that option... But it should be it.
Another hint, if at that point you presss Ctrl+Alt+F2, you should get a shell prompt. If you want to set up LVM that should be the way to do it... At the shell prompt you just type "lvm" and you shoul be able to give the right cli commands to configure LVM as well. Just if you wish, of course.

BIG PROBS with Creating RAID 0 with the Boot HD

Hey Everybody,
i have a Mac Pro with Mac OS X 10.5.3 and the folloring configuration:
1) a boot DH with 250GB
2) 2 x 500GB HD as a Raid 0 for Data
now i buy a new 250GB HD (then i have 2 x 250gb and 2 x 500 gb HDs) to create a nother RAID 0 with the boot HD... but that doesent work!
W H Y ? ? ?
i have look here in the forum fpr help, dont find a thread.
can some one help me? can i create a raid 0 with the boot hd? and when...how?
king regadrs..
christian

Lets say A and B are your 250gb drives with your current boot drive A. The two 500's are data drives C and D. My process would be to run Disk Repair on B, C and D. Then I'd run Disk Warrior on B C and D. Then boot from your DVD and run Disk Utility to repair A, just to ensure all is good. Then I would double check C and D to ensure they were duplicates, doing a Super Duper clone if needed. Then remove either C or D from your computer for safe keeping. Let's say you remove D. I would then wipe C clean and use SuperDuper to clone A to C and verify I have made a bootable perfect copy. You might even want to partition C into two drives and make two copies of A...just for temporary safety. After C has a boot copy, boot from C. Then you can use DiskUtility to create a simple RAID0 on A and B, and when that is done you can copy your C drive back into your A/B RAID. After booting from your RAID0 and then you can copy your data back from D to C (after reformatting C).
You cannot simply drag a drive from one to the other to copy it. It will not work as a boot drive doing that.
Keep in mind, if you do this, your A/B RAID has no backup. If you screw up an installation and hose it, you have nothing to fall back on. Time machine alone, or SuperDuper set to clone every day, or any of the commercial backup (or at least some of them) will give you more safety than a RAID0. RAID0 is great to save you from a single drive crashing, but more often than not the problem is installing some nasty piece of software that screws things up royally and RAID0 is wortheless for that. With your scenario, I'd buy another 250 so you can backup the RAID to that on a regular basis so if you totally screw up something you have a real bootable "last-known-good" image. After that get ANOTHER backup going to rotate off-site to save you from thieves and fires. At that point you can smile and know you really are reasonably safe. There are other ways to do this as others will explain. Several ways to skin this cat, but this is one option that will work.

VM Server installer does not recognize RAID configuration in Intel ESRT2

Hello,
I'm having a big issue here trying to deploy my third Oracle VM Server.
I have:
- A Intel Server Board S3420GPLC
- A Intel Xeon X3440 processor
- 16GB DDR3 ECC Memory
- Six 1TB Hard Drives
What I'm trying to do:
- Create a RAID array using Intel ESRT2 (Embedded Server RAID Technology II) using all the discs (done)
- Install Oracle VM Server into the array
- Install some VMs....
The problems:
- When I boot the VM Server installer from USB stick I got an error saying that there is not enought memory. This issue is solved by typing "linux mem=15GB"
- I got a screen per disk warning me about that the discs need to be initialized and all the data will be lost
- When I go to the disk partitioning screen all the disks are listed separated, the installer simply don't recognize the RAID configured before.
What I already tryied:
- Change the RAID controller from ESRT2 to Intel Matrix
-> Didn't solve.
- Create a Driver Disk with the disk images supplied by Intel here
-> I launch the installer using "linux mem=15GB noprobe=ata1 noprobe=ata2 ....". When Im asked by the installer to load the drivers it doesn't recognize the disk, so i couldn't load the drivers.
Now, the questions:
- Is there another driver I can use do make the vm server installer recognize the RAId configured?
- Is there a better way to setup this server, considering that it needs to be "self contanied" (store and run vms)?
Edited by: xyp on 14/10/2010 11:37

So...
- I have installed VM Server into ordinary linux partitions on the first disk.
- I have created a big partition in the first disc with the space not used for the VM Server
- I have created five equal partitions on the other discs
- I have configured software raid 10 using mdadm
Now the problem seems to be solved, i have a storage repository with almost 3TB and can deploy my VMs.
Unfortunatelly only my windows 2008 r2 hardware virtualized vm is working, the linux paravitualized guests not. but this new issue will be a subject for another topic.

Raid Configuration MCS 7845 (best practice)

I'm wondering what is the best practice for RAID configuration. Looking for examples of a 4 disk and 6 disk setups. Also, which drives to pull when breaking the mirror.
Is it possible to have a RAID 1+0 for 4/6 drives and have the mirroring set so that you would pull the top or bottom drives on a MCS 7835/7845?
I'm also confused that using the SmartStart Array Configuration I seem to be able to create one logical drive using raid 1+0 with only having 2 drives, how is that possible?
And links to dirrections would be appreicated.

ICM 7.0, CVP 4.x, CCM 4.2.3, unity, and the collaboration server 5.0 and e-mail manager options for ICM.
But to keep it simple let's look at a Roger set-up.
Sorry for the delayed response.

Mac Pro RAID configuration advice needed to address photography workflow

I am a semi-professional photographer and I am moving off a Windows machine and over to a Mac Pro.
I am waiting for the new Mac Pro to arrive and have purchased (4) 500GB SATA drives to replace the 250GB drive the system will arrive with.
I am considering setting up drive #1 as a stand alone boot drive. The second and third drives would be set up in a RAID 0 config and the 4th drive set up as a RAID 1 drive which would mirror the content on my RAID 0 set of drives to automatically backup the content on drives 2 & 3.
I think it would be beneficial if I describe my image processing workflow briefly so that you can understand why I am considering this RAID configuration (I've never set up a RAID configuration in the past so this is all new to me).
Image Processing Workflow
It isn't uncommon for me to return from a photo shoot with an 8GB Compact Flash card full (approx 750 8mb RAW files).
1) I plan on uploading my card to the boot drive (#1) where I would hold them temporarily.
2) I would sort thru the images and trash 80% immediately in most cases.
3) Next I would open up the "keepers" and do the initial post processing in Adobe RAW and save them to drives 2 & 3 (the RAID 0 set).
4) Further post processing (the heavy lifting and the most taxing operations in Photoshop and associated filters) would take place as I access these files from the RAID 0 set of drives.
5) All of my files would be mirrored to drive 4 as I work them. Once post-processing is complete I would copy the files from drive #4 (RAID 1)to an additional external 500GB drive for archiving purposes and then eventually delete the files from drive #1 and the RAID 0 set.
6) Once drive #4 (and the external drive) is nearly filled I would pull both and archive them and replace both with fresh drives.
Is there anything wrong with taking this approach? Can a single drive be set up in a RAID 1 configuration to mirror a set of drives in a RAID 0 configuration?
Is there anything else I should be considering?
Thanks for any assistance you guys can provide! I appreciate it!!

For the purposes of 500GB drives in RAID, I would go with WD RE2. they format to 465GB and performance falls off @ 65% and beyond anyway.
I even "short-stroke" drives to just 60% and then stay within 1/3 full - if I want to insure the maximum I/O.
Memory: 4GB is pretty much minimum but using more than 8GB isn't efficient. Ideal: 4 x 2GB.
Shame that the Hitachi 1TB drive costs over $399 for now, fast and might be better than 10K Raptor. There are also 750GB drives for $249, but the RE2 isn't quite ready to ship.
Never want to get into using 75% or more usually, though large (8-20 drives) RAIDs can hold sustained I/O for video editing and multiple streams.
One 750GB or 1TB (930GB formatted, 800GB "usable") might make sense.
How about a SATA drive case w/ hot-swap. Think of 1TB "floppy" if you will :-)) Unlimited archiving of projects.
All you want is an inexpensive eSATA 1x 2-channel PM controller and any cases. Two drives that you can use drive trays as needed.
there are also 'spare' drive sleds if you want to have the option of popping a drive out, and use it internally. $29 each or $49 a pair.

Vista 64-bit can or does work quite well now on Mac Pro... if you ever get into a jam and just need to. SP1 by end of the year will even have more support for UEFI 2.0 (Apple uses Intel EFI 1.1).

Issues with RAID Volumes with SLES10 on x4100

I upgraded an x4100 from SLES9 to SLES10 with 4 SAS drives which were configured as 2 RAID-1 volumes in hardware and am having problems with the names that these devices get.
The root file-system was installed on the 1st volume, /dev/sda, and the other volume, /dev/sdb, was mounted at /local.
Even at installation, the 1st volume was named /dev/sdb and the 2nd volume, /dev/sda. I had to pull out the 2nd volume so that the 1st volume would be correctly named and I could proceed the update.
After the update was successful and the system booted with no problems, I tried to insert the 2nd volume set again, but the MPT driver would insist on swapping the device names, leading to a hard freeze after complaining about failure to mount the root file-system.
Is there any way to fix this issue? I tried installing the driver for SLES10 from LSI Logic's website, but the problem persists.
Thank you.

I'm assuming SLES10 is a 2.6 linux kernel, which now includes the new hardware device naming scheme based upon the UUID (unique unit ID) of the hardware. The scheme is called "udev", and it runs at system startup.
When the system starts, 'udev' looks for the uuid's of resident storage hardware, and assigns and creates a /dev entry for each unique UUID. With this scheme, you could then move a disk from slot 0 to slot3, for example, and it would retain its /dev entry. So, for example, if the disk in slot 0 was named /dev/sda, and it was moved to slot3, it would still be mounted as /dev/sda.
You might want to 'clear' your device names (there is a procedure to do so... check the SUSE docs), then restart the system, verify your raid configuration, then allow the reboot to assign new /dev entries.

Which RAID Configuration for my WD "My Book Mirror Edition"?

About to reformat my WD "My Book Mirror Edition" to use on my iMac. I hope to also install on my iMac "Virtual Box", "VM Fusion", or "Parallels" and then run a few windows products. Which RAID configuration should I choose in the WD "drive configurations" box?

If I were you I'd run any Virtual Machine directly on your iMac, not on a "WD My Book Mirror Edition", in particular not when connected through USB 2.0.
To store data, the WD is fine.
For the RAID options:
RAID 0 ("striping") : if you want something fast (insofar this is possible with a USB connection). Note that when one of your disks fails you can say goodbye to all your data.
RAID 1 ("mirroring"): more safe. If one disk fails, the data are recoverable as they are on the other disk as well. Disadvantage is you get only half the storage capacity compared to RAID 0.
Oh. my personal recommendation: RAID 1 is not an alternative to making a backup. So whatever option you choose: if you store valuable data on the disk that are nowehere else: back them up!
On formats:
HFS+ : definitely recommended if you only use the RAID array on the Mac.
FAT 32: if you also use it on a Windows machine. Note that files cannot be larger than 4 GB in this case.
Hope this helps.

Best Raid Configuration for a 8-1tb hhd server

Hi All,
I have been trying to figure out what would be the best raid configuration for my Windows 2012 essentials server. So I was wondering if I could get some advise on this. Here is what I would like to get out of this configuration.
I would like to split the 8-1tb drives into 2 VHD one with about 300gb for the OS to be installed on, and the rest to be use for storage. I want like to have good redundancy, fairly good read & write capabilities.
I will be using this server for a Small Web Page and Game Hosting, Email Exchange, Critical Application hosting.
I would like the ability to enlarge the overall raid storage by swapping out my 1Tb drives with 2Tb or larger as the need for more storage arises.
Any help would be greatly appreciated,
Thanks

You may be better of using Storage spaces and not using raid at all.

Error in RAID Configuration

Now I am receiving this message: Your device My Passport (S/N: ***************) has RAID configuration issues.Please launch the WD Drive Utilities software to get more information. My options are to click on run wd drive utilities which i uninstalled...

Am experiencing exactly the same problem that e_silio describes on my MacBook Pro (late 2008 running Yosemite 10.10.4). I also have a DROBO (a "better-than-RAID" backup system) attached to Firewire port on which I have my Time Machine and an Archive partition. With the WD software installed the drive mounts for about 10 seconds then dismounts and the LED goes off. With the WD software uninstalled the drive mounts, then dismounts but LED continues powered (blinking), and the "Error in RAID Configuration" popup displays as already described. However, when I dismount the DROBO, uninstall the WD software <reboot>, the drive stays mounted! BUT... When I install the WD Drive Utilities, let the app update to the current version (2.0.2.18 May 19, 2015), and run the "Quick Drive Test", THEN the drive dismounts. Now, disconnect the drive and re-connect: it remounts four about a minute and then dismounts again. Uninstall WD Drive Utilities, reconnect the drive, then the "Error in Raid..." message returns. (The DROBO is still disconnected from the computer). It is quite frustrating to need to fuss with such a basic device.

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.
