Setting up a Raid O system.

I have a P5E motherboard with 6 SATA slots. I have been in the editing universe since 1999 and have never used raid as I always found it very complicated to set up. However for an upcomming projet I would like to be on top of things and get rid of the eternal hard drive bottleneck problem. What is the easiest way to set up a RAID 0 system and could somebody here please guide me through the essential steps. I just was never able to figure it out. Thank you

I would highly recommend setting up Raid 10, not Raid 0.
In my hardware based system, I just added drives as members in the Raid setup from the BIOS.
Four 500GB drives give me 1TB of storage with a combination of striping and mirroring.
I actually had a hard drive problem, and never even noticed it. The next time I booted, I saw the problem, went into the Raid BIOS, removed the bad drive from the Raid and then added it back in. The Raid rebuilt itself without me doing anything and returned to "Normal."
While it's good to have someone who knows what they are doing set it up for you, it's probably better to try it yourself so you know what's going on if there's a problem in the future, IMHO.
Just don't start experimenting two days before that huge job is due to start....:)

Setting up a RAID of system drives

hello everyone,
I am looking to add a second system drive for more hd space. I was planning on purchasing a second Raptor and setting up a RAID 0. will I need to format my existing drive, or can I just plug in the new drive and set up my RAID in DU?
...any feedback appreciated, thanks.
Dual-core PwrPC 2.0ghz G5 2mb RAM Mac OS X (10.4.6)

Ok,
You already have a Raptor as boot, most likely it's a 36 or 74GB with 8 MB cache and it's hooked up to your internal SATA ports.
To create a RAID O, you must match the two drives exactly. Erase w/Zero both of them, create the RAID O set in Disk utility and clone your boot drive back from a booted external drive using cloning software. (meaning you have to first clone the original to a external then boot from it and clone to the RAID O)
Problem: Western Digital has updated all their drives with a new SATA spec, also increased the cache to 16 MB. The PowerMac's can't handle the new SATA spec (supposedly the Quad can, but I'm hearing mixed stories)
So unless you find a 8MB cache Raptor, your going to need to spend more money.
The solution if your determined to have RAID O Raptors, is to buy two of them, preferably the new 10,000 RPM 16MB cache 150GB ones, and a Firmteck SATA PCI card (the only one that's bootable off of) with 4 internal SATA ports and 4 external ports. Then hook the internal Raptors to that.
The Firmteck card will also give you the option of hooking up external SATA drives in a powered enclosure, one cable to each drive. So you can expand if you wish.
With a RAID O, you must clone (for a whole boot drive) or backup (for files) quite regularly, like at least once a week for clone and daily backup for files. Since one should be doing this anyway, it's really no big deal. Because like the other poster said, RAID O is a bit more risky, one drive goes you lose all data as the data path is split. But the speed is worth it. So with a pair of 150GB Raptors your going to need a 250-300GB drive external Firewire 800/400 drive.
Now to keep a drives performance up, you shouldn't fill it more than 50%, and certainly shouldn't fill a boot drive more than 80%. So one can use a 250GB external drive for clone backup as long as the data on the 300GB RAID O doesn't go over around 240GB. (80%) Get it?
LaCie makes a good Firewire 800/400/USB d2 drive.
However if this is a bit too much to bear on your wallet, then what you can do is reduce what you have on the boot Raptor below 50% by moving just what you have in documents, pictures, movies and audio files into NEW folders on a second internal SATA drive (preferably one with 16MB cache not from Western Digital)
Once you have slimmed up your Raptor, then clone the whole drive to a external drive, option boot from it and make sure everything works correctly, repair permissions and test all software (some copy protected ones will need to be fixed). Once your are 100% certain it's ok, then Erase w/Zero the Raptor and clone the whole drive back.
What this will do is optimize the Raptor boot drive drive, free up disk space, de-fragment large files/apps and sort of tighten everything up to the most fastest part of your boot drive, the outer tracks, in the good part of the 50% side of your drive. (vs the inner tracks where performance starts to suffer)
Without the space hogging files that are now on the second SATA drive, your drive freshly optimized, the arm in the hard drive has less space to travel to get your data that Mac OS X, apps and random music files iTunes needs to constantly access.
Now I suggest using Carbon Copy Cloner to do your optimizations with, because I know how this program clones drives, in alphabetical order on the main directory of your boot drive. So Applications, Developer (if you have installed Developers Tools from Tiger install disk) Library, System and finally Users at the end (where it could expand without de-optimizing your drive)
Always follow these rules when cloning.
1: Don't run or do anything else while a cloning process is going on.
2: Always Disk utility Erase w/Zero option all new drives one time or in the case of a security issue.
3: Option boot from the clone and check it out.
4: Repair permissions BEFORE and AFTER each cloning.
5: Avoid partial clones because of copy protection schemes hiding files on the drive.
6: Avoid cloning to partitions, especially on the same drive, because if the drive fails mechanically your screwed out of your clone as well. Keep it a boot clone to a boot clone on a separate drive.
7: If you can keep two clones of your boot drive, just in case you get hacked or have a exploit, because when you hook up the second clone, it will get owned too and possibly erased. If this happens, C boot off the installer disk (write protected) and Erase w/Zero all infected drives and disconnect from the internet/network before hooking up that last clone.
I wrote a book, I hope it helps.
Note to others: Firmteck SATA PCI card will not work in PCI-Expressed based PowerMac's.

Replacing a hard drive of my RAID 5 system just ruined my OS X 10.6.8 server... help...

My system is MacPro 2009 with 10.6.8 server and Apple RAID card. Last week, RAID util just notified me of one drive is not viable, so i decided to replace the drive today. The configuration of my system is...
There is an Apple Raid Card for HW Raid system
Bay 1 = 640 TB drive with Mac OS X 10.6.8 server installed
Bay 2, 3, 4 = 1.5 TB drives set up as RAID 5
below is what I did to replace the degraded Bay 4...
1. I shut down the system
2. replaced the corrupted drive with the new hard drive
3. tried start the machine again...
Now my machine refuses to start up with the blinking question mark... I guess that the system fails to recognize the new drive or cannot find the system files...
4. So I put back the degraded drive...
5. The machine still won't start...
6. I tried to use the 10.6 server installation disk to boot up the machine to check if I can fix the system via disk util; but, everytime I do this, I got kernel panic...
7. resetting PR Ram didn't help, cannot boot up via safe mode as well (since the system file is not accessible now, I guess...).
8. booting via 10.6.2 server installation DVD still gives me kernel panic...
Why would my system corrupt by just replacing one degrade drive? The Mac OS X is not even the part of the Raid system... How am I supposed to fix this issue with out the installation disk?
This Apple Raid card is driving me nuts now...

Something weird is definitely happening to my OS HD. Here is my updates to the problem.
1. I just put the old corrupted HD into the Bay 4, and tried to restart the machine again.. still not bootable
2. So I replaced the OS HD from the Bay 1 with a new blank 2TB WD green drive, and use the 10.6 server DVD to boot up the machine. This time I didn't get the kernel panic.
3. Checked the RAID partition, everything is still intact, but the RAID utility is still complaining about Bay 4 being not viable...
4. I replaced the blank drive from the Bay 1 again with the previously installed 10.6.8 server HD. This time the machine refused to boot up and threw that infamous folder with question mark error...
5. So, I replace the bay 1 with blank HD, and installed the 10.6.0 server this time. The RAID partition is now initialized and can bee seen from the OS. RAID utility still complains about one disk being not viable. Now I am syncing and backing up all the data from the RAID 5 partition and try to figure out what is wrong here...
More specifically, my current set up is...
bay 1 = 2.0 TB JBOD+
bay 2 = 1.5 TB registered to RAID 5, viable but degraded
bay 3 = 1.5 TB registered to RAID 5, viable but degraded
bay 4 = 1.5 TB registered to RAID 5, not viable
The previous OS drive was also set up as JBOD+ to the RAID card, and was not supposed to be a part of the RAID system. I wonder why changing one drive at the Bay 4 did corrupt the system, though.
Also, now I am a bit freaked out and do not dare to change any drive yet... How am I supposed to appropriately change the failed drive? Should I just shut down the system and remove the drive from Bay 4 like last time?

Setting up a RAID 0 between the Mini's internal HD and an external

Would it be possible to set up a RAID 0 between two hard drive, one being the internal drive of the MacMini and the other being an external firewire drive?
Would these two drive have to be configured outside of the computer in external enclosure and then one transplanted into the mac mini, or will the operating system allow this to be set up between the two drive?

Yes you can RAID the internal Mac mini 2.5" hard drive with a FireWire external, but a striped RAID set is always limited by the speed of the slowest drive and the size of the smallest drive.
As such I would not expect much of a performance gain and you would have to erase your internal drive to create the striped RAID set while booting from a 3rd drive to setup the RAID0.
Using a FW boot drive will give you increased performance. You can see details here:
http://www.amug.org/amug-web/html/amug/reviews/articles/wiebetech/max/
Or if you really want to speed up the Mac mini read about the AMUG Super-mini project which uses 3.5" SATA hard drives. It was tested in single and RAID0 configurations on the internal ATA/100 IDE bus of the Mac mini

What RAID storage system should I use?

To set the stage here. I'm somewhat of a newbie to the video industry. I've worked as a videographer for a non-profit for 5 years. At that job, we just skimped by on what we could afford, which wasn't much. I just started a new "professional level" job for a school district and have been given the keys to a fairly substantial budget to get whatever I need to do the job.
I want to do right by them and not waste money, so I want my purchase decisions to be educated. I'm an intermediate computer user, but have never used raid configurations before, so please be kind. Also, we can really only purchase through a few vendors. B&H is where I'm getting all my other video equipment, so I'm only looking at options available there for my storage needs as well.
Right now we record using Canon XA10 and XA20 model cameras. I'm hoping to upgrade to XF300's with this new budget, but still we're only talking MXF files, 1920x1080 at 50Mbps 4:2:2. So I'm not dealing with huge uncompressed footage.
Still I record a fair amount of footage. In the first 2 months on the job I've accumulated about 460GB of raw video, and I don't expect demand to go down in the future.
Right now, my idea is to purchase two Western Digital 12TB Raid Arrays in Raid 0.
http://www.bhphotovideo.com/c/product/1053138-REG/wd_wdblwe0120jch_nesn_12tb_my_book_duo.h tml
(I should note, I'm using a Windows 7 PC, so I only have access to USB 3.0, not Thunderbolt)
The first raid array would be my scratch disk, the second would be used for manual backup at the end of every day. (Using a utility like SyncBack)
Once my projects are complete, and I'm sure I won't need to access them, I'd like to move them off to a 3rd RAID array like this set up in Raid 5 for redundancy.
http://www.bhphotovideo.com/c/product/1018063-REG/owc_other_world_computing_mercury_qx2_4_ by_hw.html#specOWCM3QX2K0GB
This array would serve primarily as an archival unit, with only occasional transfers to it and use in only rare circumstances where I need access to several month old footage.
Do you have any suggestions of a better system or workflow?
Thanks so much!

Would be good to raise this over on the:

Setting up a RAID

I just got another internal hard drive for my Mac Pro, and I'm thinking setting up a RAID between two drives. I read some documentation here on Apple, but I wanted to check and make sure about one thing. Do both of the drives I plan to set up a RAID need to be erased first? It doesn't say that in the documentation. Or can precede with the RAID even though one drive has data on it and the other doesn't.
And finally, if I plan to add VISTA to RAIDed drives, will that be a problem?
Thanks for the feedback.

All drives used in a RAID will be erased. You cannot add an active startup volume to a RAID. You cannot use a RAID for a Boot Camp Windows installation. If you install OS X on a RAID you will not be able to install firmware updates for your computer.

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?
You would be wiser to use you second drive to backup your main drive and forget about RAIDs. They are of no real value to the home user like yourself. RAIDs are used mainly for large enterprise servers and very fast data storage systems.

Set up a RAID 1 with four Hard disks with DiskUtility

I have a Sonnet Fusion-500 RAID enclosure with four hard disks of 500 GB (2TB total) connected to a Power Mac G5 (2x2.3 GHz, 2GB RAM, MacOSX 10.4.8) through a Sonnet Serial ATA PCI express card (Tempo E4P model). Since I have a total capacity of 2 TB, I would like to set up a RAID 1 (mirrored) and combine the four drives in a final working volume of 1GB, (and the remaining 1GB in the mirror volume). I've been trying to setup the RAID with DiskUtility, but I cannot get a working volume of 1 GB (only 500 GB -the size of a single disc-). Can anybody please give me some help in setting up this type of RAID?
The four 500 GB discs are OK, since I can create a RAID 0 (~ 2 TB) or initialize them al individual drives without problems.

How can I tell if HD is set up for RAID?

I received an external Western Digital 4TB drive with some files on it and I'm trying to tell if the drive is already set up for RAID or not. The company I received it from couldn't tell me and according to the WD box, it's "pre-configured for maximum capacity (RAID 0)". However, when I go into Disk Utility to view the drive, it says the capacity is only 1.8T.
I little more detail... In Disk Utility the left window shows the drive named, "1.8 TB WD My Book Media". Total capacity 1.8TB
S.M.A.R.T. Status: Not Supported
Partition Map Scheme: GUID Partition Table
...In the Partition window it looks like a single partition. Again, Size: 1.8 TB, Available space: 1.1 TB.
Does this make sense? Sorry, I'm not familiar with RAID drives and how they're set up and used. Any help with this would be greatly appreciated.
I'm just trying to find if this drive is in fact set up as a RAID drive and if so, is it mirroring to the second drive in the enclosure? or not? And if not why does it say that the drive is only 1.8 TB?
Sorry for the rambling.
Thanks.

There is no such thing as a "RAID" drive. Any drive can be used in a RAID array. A single drive is not a RAID drive. It is simply a single drive. When multiple drives are combined into an array via software and/or hardware then one has a RAID array.
Now as far as I can determine WD does not make a single drive larger than 2 TBs. Formatted the drives will contain roughly 1.8 TBs. WD does make a My Book version that has two 2 TB drives that can be configured into a striped RAID array that will provide 4 TBs of storage. I don't know if the product is pre-configured as a RAID array or if you must configure it as such using Disk Utility. For the latter you must first partition and format each drive then use the RAID tab option of DU to set up the RAID array. Select Disk Utility Help from the DU Help menu and search for "raid" to get the help articles on how to set up striped or mirrored RAIDs.

Setting up a network backup system

Looking for advice on buying the proper equipment and setting up a good backup system for my home network. I have an Imac, 2 others on the network with a Macbook and an older imac. I havea fairly new Cisco router.

The PC's go into sleep mode? Can you check your power settings.
Change the scheduled to a time when you know the pc is on and can monitor it. Log off the PC and see if it backs up. At least this will help narrow it down.

Need suggestion on importing BC SET : UKM_DCD_CUST in SAP ERP system

Dear Gurus,
Client wants me to import BC SET : UKM_DCD_CUST into SAP ERP system. I have found BC SET : UKM_DCD_CUST in T code SCPR20.
I have read most of the SCN discussion and got two way to import BC SET into ERP system as given below. But I need the appropriate way to do this. Can any one help me in this?
1. SCPR20 -> Activate BC set -> create customizing request to import into another system as per link :Business Configuration Sets (BC Sets) and their use - Basis Corner - SCN Wiki
2. Create TR in SE01 in 000 and import into required client as per below proc:
Usual procedure
1) BC SETS will be attached to SAP note usually. Download it and unzip it , you will get a *.bcs file
2) Call transaction SCPR20  BC set --> Upload In the dialog box that then appears, specify the files that you unpacked
Import the set BC into a package that you have defined. activate it with the "Expert mode"
3) You will also get a *.txt file with prog id , obj etc entries , then you have to go to SE09 and create a transport request in the source client of your Solution Manager system (client 000). Open the *.txt and copy the entries it contains into the transport request. Use transaction SCC1 to import the data in your Solution Manager client(s)
Thanks,
Anand Aseri

2). Client copies bring the Customization data but not WorkBench . So you might have to do transport of copies from Old Dev to >New Dev.
So you are saying that the system copy from Production will not bring Workbench data and I need to bring Workbench data by transports?
*system copy from Production will bring Workbench data also, but when you do client copy from development system again on top of client which already has production customization, data and workbench requests, Production customization and data will be overwritten from development customization and data (it depends on the profile you choose for the client copy) *
However Development Workbench requests are more and also has ongoing development work which might not be available in production client and those (Ongoing development workbench requests) you need to import in new system as transport of copies after the client copy
3). If you do system copy from Production and do client copy from dev...obviously Prod customization will be overwritten with Dev rite ?
That's what I expect to happen,
Ok, however, You might need to get Development Work too from the old dev system and don't forget about setting up of partner profiles in WE20.
It's just a thought , Do you have testing client in Dev, if not,You can leave the production client in development system and use it as testing client.
Create new client which is client copy of Old Dev and import WorkBench requests *
Thanks,
Arjun
