Which 750GB drives used in an XServe RAID?

Could somebody with an XServe RAID with 750GB drives please tell me, which drives are used in this configuration? You can look it up in the XServe RAID admin utility, under Arrays and Drives when selecting a drive in "drive" mode.
Thanks a lot,

  • Adding Additional Drives to 3.55 Xserve RAID

    So, we just purchased the 3.55 Xserve RAID (7 500gb ADM's). I'm surprised to read that I cannot "grow" the volume by adding ADM's without reformating the volume using OS X. Is this still true?
    Our intention was to simply add ADM's as needed, however this is likely not going to work... if each time I need to offload the data and reformat the volume.
    Annoyed.

    Xsan allows you to aggregate fibre channel LUNs (analogous to "disks") into what are called "storage pools." You then aggregate storage pools into volumes. So to grow a volume, you can either add more LUNs to an existing storage pool, or you can add more storage pools to a volume.
    A bit technical.
    Keep in mind that to run Xsan, you will need a few things:
    1) A fibre channel card for every machine that wants to access the volume over fibre
    2) A dedicated ethernet network which is separate, and used specifically for metadata traffic on the volume -- this enables Xsan to do file locking
    3) A pair of dedicated metadata controller machines -- preferably Xserves with > 2 GB of RAM, to manage the SAN.
    At minimum, figure $20K on top of the storage to get started with Xsan, if you want it to perform well and be reliable. You owe it to yourself to get Xsan training and certified as well -- making errors early in the planning/deployment process can magnify later on.
    Xsan is great for what it does best -- high speed, shared, video editing -- but to just give the ability to grow a volume, I personally think it's overkill. If you can stick to one RAID you could probably do a concatenated RAID volume with OS X's built-in RAID.

  • HUGE Troubles with xServe RAID formatted 10.4 and using it with SLS 10.6

    Hi All,
    We met today a huge trouble using an Apple xServe RAID (formatted HFS+ with a Mac OS 10.4 Server PowerPC G5).
    This RAID has been plugged with a new xServe Intel Xeon (Model xServe 3.1), MacOS X 10.6.2, Apple FiberChannel card 4 GB, the link is at 2 GB.
    There is also an Infortrend RAID FiberChannel 4 GB Fiber to SATA RAID attached to this new Intel Xeon server : this RAID drive mounts correctly, no troubles.
    BUT the "old" xServe RAID is not able to mount at all while plugged with this new Intel Xeon, DiskUtility claims the volume needs repair !!! We try a repair = failed !!!
    The xServe RAID has been formated under 10.4.6, HFS+ Journaled.
    The Infortrend has been formated under 10.6.2, HFS+
    Does anyone met a such case ??? We tried using SFP to SFP Copper cable or Optical Fiber + SFP/LC Transceiver = same results
    Many thanks a lot for your opinion !!!
    Regards.

    What if you connect your "old" xServe RAID to a non SLS server if you have one available? Preferably one running 10.4.x server to match your HFS format. If the data on the old RAID is so critical that you can't afford to lose it, you could always pickup a used PPC w/ a fibre channel card and install 10.4 server on it just so you can transfer the data. Curious to see what you end up doing.

  • 750GB Drives in Raid 0

    Hi,
    I want to add 3 of the Seagate 750GB drives and set them as RAID 0.
    Anything to watch for with the drives and how can I make this as inexpensive as possible?
    B

    Just connect the drives and format. That's all there is to it.
    You might consider changing the block size depending on your
    typical use.
    Cost is mesured only by the cost of the drives themselves.
    For price proformance I like the Maxtor Maxline III drives
    the best by far. In a RAID0 they're pretty nice according
    to both test-bed sites that have tested them and to my own
    findings.
    Have fun!

  • How to low-format disks in XServer RAID

    I am new to the macworld and have been assigned a mission to low-format 2 XServer RAID with 28x400Gb Hitachi Deskstar disks. I need to low-format it because the customer is about to sell the servers, and are therefore obliged by law/or insurancecompany to make sure that no data can be restored.
    I have tried to extract the disks and run them in a PC with a software called KillDisks, which writes zeros to the disk 10-fold times. However the PC will not accept the disk, im getting errors that states that no sectors can be read. Also, in BIOS the disk are supposedly 126 Gb...when in fact its capacity is 400 Gb.
    Sounds like the Apple firmware is not compatible.
    So, my question is...can I perform this task from inside the XServer, via some webinterface or perhaps the remote adminapplication?

    I see you point but I mostly meant the need to extract/take apart the drives.
    The job was to make the data (reasonably) "unrecoverable"?
    (The KillDrive application can maybe even "destroy" drives for Xserve RAID use?)
    Maybe not relevant here but the Xserve RAID woun't "buy"/just work with "any" drive/firmware.
    He shouldn't even have to "reformat" raid-sets as you can write zeroes to each whole raid-set volume from the Disk Utility using the "security option" (will take a lot of time though - but probably much less time than doing it for each drive individually - if JBOD or otherwise).
    Maybe even possibly started from OS X install DVD (if servers are "wiped"). Don't know if FC drivers are present on the DVD, but think they are.
    (Also a "Mirror Door" G4 or Xserve G4 can probably "format" (really initialize) these drives and can at least hold up to 4 drives at a time.)
    And you can manage (but not erase drives/volumes on) the Xserve RAID from any computer (if you know the IP) using the Java RAID_Admin.jar file that is "extractable" from The OS X version file (.app) "package". And it can be run on (most?) OSes that can run Java. Certainly from Windows with Java installed.
    And you don't buy a couple of old preowned used Xserve RAIDs and spend a huge amount to restore data if you don't think/know it's REALLY worth the while.

  • Xserve RAId MTBF

    Hello,
    Acn anyone tell me the MTBF (Mean Time before Failure) of the Apple Drive Modules for the Xserve RAID.
    Thanks!

    IBM don't seem to publish MTBF figures for their drives. However, other similar drives run in the 1 million+ hours MTBF and I'd be surprised if Apple went with a drive that was way out of line of other manufacturers.
    MTBF has proven to be a poor gauge of disk failure rates which may explain why they no longer publish them.

  • Dropped frames only on xserve raid

    dropped frames only on xserve raid
    i'm not able to capture on xserve raid without dropped frames. tihis was a working sytem bud one morning it dosn't work. i capture on mac pro internal drives or external fw drives without problems.
    the xserve raid is new formated in raid level5 [mac os extended journaled and striped in raid 0 extended] and the risult of kona system test are 178mb/sec write and 167mb/sec read.
    must bee enought for 8bit uncompressed pal, no? also if i divide the stripe set the system dosn't work on both controler. i tried also to change the fibrechannel cables!
    i checked also the fibrechannel card with expansion slot utility and the message is that runns at maximum speed.
    there are no error message on raid admin, the xserve raid appears ok.
    i'm shure that the fcp settings are ok, i know the list that regard dropped frames from apple.
    i'm desperate, can you help?
    thanks jochen
    system:
    mac pro 2x3ghz-5gb ram(from apple and the hardware test on the system dvd is ok)
    osx 10.4.10
    fibre channel card: lsilogic firmware 1.2.18.0 in slot 4
    xserve raid 15x250gb firmware 1.5.1/ 151c
    aja io (driver 3.0)
    raid admin 1.5.1 (diver 1.0)
    fcp 5.1.4

    I'm guessing conditioning is the same as optimization, but I can't find anything about it in the help documentation. I ran another capture test today with no problems.
    An interesting side event is that when I started experiencing dropped frames I ran the Kona System Test utility to verify write and read speeds. It wouldn't run (no write or read) on my RAID. I tried it on my Firewire drives with no problems. I discovered that in the Kona System Test preferences there is a choice of I/O API for Macintosh or Unix. When switching to the Unix I/O API the test ran fine with expected read and write speeds reported. I've used the Kona utility in the past without having to change that setting. I sent an inquiry to AJA.

  • Thoughts on xServe RAID replacement?

    Hi everyone. Thanks for reading.
    I am replacing an aging xServe RAID in a clients network. They currently use the xServe RAID as storage for their mobile home folders, company file shares (RAID 5 w/ 500GB storage), mailstore (RAID 1 w/ 250GB storage) and backup for other servers (RAID 5 w/ 3TB storage). This is hooked up directly via FC to an Intel xServe running 10.6.8 server. They would like to replace this simply because they need more storage for files, and the age (about 7 to 8 years old).
    I would still use the existing xServe RAID as backup storage, however, we are looking for replacements. Right now I am pricing out a Promise VTrak E-Class with 8TB of storage (most likely will go RAID 10, so 4TB of useable storage) and a new 4Gbs quad fiber card. Total for both is around $8500. I am not convinced however they need that fast of storage for their use. They can get a Drobo 800i (bear with me here) with 8TB of storage (if dual drive redundancy is on the useable is around 3.6TB)  and a dual 1GB PCI ethernet card for around $4300. In the past, we have only used the DroboPro, and think that particular unit is too slow for anything but archival data or backup. We have yet to use the 800i (nor the 1200i).
    What does everyone think? Or is there another product we should also be looking at? Network is 1GB for around 40 users. Mobile accounts just sync at logoff, and useage of file shares is probably light to medium.
    Thanks again.

    The Promise range is what Apple originally recommended as a replacement for the discontinued XServe RAID. However you could also look at Active Storage, see http://getactivestorage.com/
    They even have a 1U rackmount box that can act as an XSan metadata controller (instead of an XServe).

  • Mac Pro + XServer RAID + FCP2 + Configuration

    Hello all. This is my first post here.
    I will soon buy a MacPro por video editing on Final Cut Pro 2 and I was wondering if you could help sort out if the configuration I've chosen is the best.
    I'll show you the configurations I thought first:
    *Mac Pro*
    - Two 3.0GHz Quad-Core Intel Xeon
    - 4GB (4 x 1GB)
    - Mac Pro RAID Card
    - 2 x 500gb HDD
    - ATI Radeon X1900 XT
    - 20" Apple Cinema Display + 23" Apple Cinema HD Display
    - Dual-channel 4Gb Fibre Channel PCIe
    *XServer RAID*
    - 2000GB ADM (4x500GB Ultra ATA)
    - Cache Battery Back-up Modules
    - Dual-channel 4Gb Fibre Channel PCIe
    My idea:
    A) The MAC Pro I'll be used for 3D rendering and video editing. I'll configure the 2x500GB with RAID1 (mirroring) for a fail safe env, leaving my with 500GB of available space
    B) XServer RAID will be connected directly to the Mac Pro (for now) via the fiber optic cards and we'll provided additional storage.
    C) For projects stored on the XServer RAID (videos for example) I must be able to access and edit directly with FCP2 without having to pass it to the Mac Pro
    D) I was thinking of using RAID5 for XServer RAID configuration leaving me with 2.64 x 500GB (as described on support faqs) = 1.3 TB of disk space with a reasonable fail safe environment (RAID5 with 3 drives allows one drive to fail and offers a good recovery rate).
    OK. My questions:
    1) Is my MacPro config enough for FCP2 + 3D Rendering ?
    2) Can I use the XServer RAID directly with Mac Pro or do I need aditional software / hardware?
    3) Can I connect the fiber optic from one board to the other without using the router? (on google the answers I found were very vague...)
    4) Is the RAID5 the best choice (in terms of performance vs data recovery) for video editing. The RAID5 specs states that random writes to disk are slower that other RAID configs. Is RAID 50 (5+0) a better choice?
    5) I opted for the 4 HDD config on XServer but I could change to a 7 HDD config for a similar total space.
    I'm sorry for the long post, but I can't find anywhere suitable information about this questions.
    Hope to hear from you.
    Thanks in advance!

    We have a ton of Xserve's and Xserve RAID's at my work. As of right now they're all directly connected to our servers with Fibre Channel cables (NOT fiber optic, totally different animal.) We finally just bought our first Fibre Channel switch to hookup five 10.5TB RAIDS and a huge tape loader for backups. The RAID's work perfectly when directly connected and are very fast. The only reason that you would need a Fibre Channel switch is if you want multiple machines to be able to access the array without using network shares.
    I really don't think that just four drives will give you the performance that you're looking for. In order to get good performance out of a RAID5 you NEED as many spindles as you can get. If you're stuck to a budget if would probably go to smaller drives but get more of them. I think you've already discovered this but if you want to do a RAID5+0, you'll need to populate drives on both sides of the RAID as they are physically seperated.
    As far as I know, you can only get Xserve RAID Drive Modules from Apple as they do some pretty intensive testing on every drive before they ship. You can't even buy empty modules, you can buy blanks but they don't include the required electronics.

  • Does Xserve Raid 3.5 TB supports HD uncompress?

    Does exist any configuration for Xserve Raid 3.5TB 7 drives, that supports HD Uncompress 720p 10 bit video formats?
    Will I get that only with 14 drives?
    Can I get that with 8 drives? 4 drives in each controller.
    Thanks

    What's the data rate -- how many frames per second?
    A common list is on the Xsan page:
    http://www.apple.com/xsan/videoworkflow.html
    I'd say if you're at 24 or 30 FPS:
    720p 24fps 46MBps
    720p 30fps 50MBps
    You would be okay with 7 drives in half an Xserve RAID. If you need more than that, you'd need 14 drives.
    If you're doing 1080i uncompressed, definitely you need all 14 drives striped in a RAID 50.

  • Dropped frames on Xserve RAID upgraded w/750GB drives.

    I'm capturing in 10-bit uncompressed standard definition 720x480. I just upgraded one side of my Apple XRAID, (connected directly via fibre channel) with seven, 750GB hard drives from Apple, drives designed for the XRAID, (came with there own sleds.)
    Current Xserve RAID firmware version is at version 1.5.1/1.51c
    Before the upgraded drives, no issues with dropped frames, (drives 1-7) the other side of the same RAID has no problems, (currently running 250GB drives, drives 8-14.) All sleds are populated with drives of the same capacity, (respective to each side.)
    The drives were formated using the Xserve RAID Admin software and mounted using Apples Disk Utilities, Journaling turned off. The final formated capacity of the RAID on drives 1-7 is 4.1TB.
    When I capture to the drives on the upgrade side, I get dropped frames. When capturing to the other side, no issues, works great. I checked the settings for performance and they are the same for both sides, as follows:
    Use Controller Write Cashe - ON
    Allow Host Cashe Flushing - OFF
    Use Drive Write Cashe - ON
    Use Steady Streaming Mode - OFF
    Read Prefetch: 128 stripes (8 MB/disk)
    My capture box is an AJA I/o and has never given me dropped frames till now, but only on the side of the RAID that has the new 750GB drives. I also have another RAID that uses 500GB drives on both sides and it work just fine as well, (no dropped frames) using the same performance settings in XRAID utilities.
    Any suggestion on why these new Apple drives modules are dropping frame would be very much appreciate. Again 7 new 750GB drives from Apple w/sleds having dropped frame issues.

    I'm capturing in 10-bit to avoid loss of quality from analog sources like BetaCam SP as well as line 21 must be part of the captured file, because it contains line 21 for captioning. Eight bit has a banding issue that I can't have in the final product and 10-bit doesn't have this issue.
    Source quality is maintained completely when working in 10-bit uncompressed, as well as the captioning data that I need, which is stripped out of the captured video latter. Captioning software can read line 21 of the raster area, of the captured file.
    Source video is from BetaCam SP, DVC Pro and DVCam.
    The RAID is an Apple Xserve RAID, connected via Fibre channel directly, (no xsan.)
    I also create high quality QuickTime Streaming files from these source files, the higher the quality of the source video the the better the streaming files look when created.
    I have never had any problem capturing till I installed these new drives from Apple.
    The RAID is as stated above, is an Apple Xserve RAID, connect via a fibre channel card in a Mac Pro 3.0GHz tower, (no xsan is used, due to connecting directly to the XRAID.)

  • Does the original Xserve Raid (2003) support 750Gb drives.

    Is the latest firmware compatible with the original Xserve Raid, thus supporting 750Gb discs?
    Thanks in advance.

  • Xserve Raid - use it as standalone storage?

    hi there!
    i have a small network with some pcs (3 running winxp, 1 win2000), 2 os9 macs and 2 g5s. i need big data storage in the size of 7-10TB. can i use the Xserve Raid as standalone storage in the network, or does it need the xserve as server?
    do i need soomething else apart from the Xserve Raid to setup the storage bank?
    is it a good idea to connect the pcs via ethernet and the g5s via fibrelink? (because our files we are working on are very big and need to have fast access on the storage drives)
    thx for ur help
    manuel

    The XServe RAID needs a host system. That host system doesn't need to be an XServe, or even a Mac - people are using them quite happily on Solaris servers, Linux servers and even Windows servers.
    However, it does need a system that had Fiber channel.
    ALL disk activity happens over the fiber channel connection. The ethernet ports are not used for file activity, only for administering and monitoring the box.
    If you hook the XServe RAID to a single host via fiber channel, that host can share the volume over the network to other clients so they get indirect access. Alternatively you can use a fiber channel switch to connect multiple systems, but care needs to be taken with regards to multiple clients reading/writing the same file at the same time (which is typically why you need SAN software to manage this kind of setup).

  • Cannot map or even see drives on xserve RAID hanging off a xserve

    Sorry if I sound like a complete idiot, but when it comes to Macs I am one. We have a OS X Server 10.5.8 and a xserve RAID. The RAID looks ok and under the server I can see both of the RAID drives that have been created and access them. When we try to map to it on one of our house Macs, its errors out with "There was a problem connecting to the server." When we try to map to just the root of the server, we can see its hard drive, but not the RAID drives. Any help would be most appreciated!

    By default, Mac OS X Server only shares the root drive.
    In order to share external volumes (such as the XServe RAID volumes) you need to use Server Admin to mark the volumes as shared (as well as which protocols to use).

  • Xserve RAID - Multiple drive failure.

    Morning all,
    An Xserve RAID I have been called to take a look at is behaving rather erratically! Here's the chain of events over the last 3 days:
    (4 x 180GB - RAID 5)
    - 2 folders (the largest in size) suddenly appear empty. The capacity and available space do not change.
    - Some remaining files and folders appear corrupted / incomplete e.g. Quickbooks company file.
    - Data Rescue appear to recover all data, missing files are recoverd as "orphaned" files.
    - DRIVE 1 FAILS showing red light and disappearing from RAID admin.
    - RAID set shows "degraded" but still accessible due to RAID 5 config.
    - Replace drive 1 with 750GB Apple supplied drive.
    - RAID 5 set rebuilds automatically showing green and "online"
    - missing files in the 2 large folders still appears missing.
    - DRIVE 2 FAILS
    I believe the chances of 2 drives failing in such short succession are extremely small and I now thing that drive 1 is probably ok and that something else is at fault here.
    Xserve RAID is on the latest FW 1.5.1 and no other errors are present.
    Can anyone shed any light on this, could it possibly be the controller ?

    The act of the rebuild could have been enough to push the second drive over the edge.
    I would say... if the Xserve RAID has been running 24x7 since you purchased it, you may want to consider replacing it. The 180 GB drives were discontinued almost 5 years ago from what I recall... 5 years of constant use is really a long, long time for had drives. It's more typical in data center usage to replace drives after about 3 years of use (even if their MTBF is 500,000+ hours, those numbers are rather meaningless). Hard drives fail on a "bathtub curve," where once you get to the far end of it the odds of failure are great, and lots will fail around the same time. You can't rely on the Xserve RAID to run 24x7 for 10 years, or you'll definitely have problems. There is no RAID on the planet you can expect to run for 10 years without issues with the drives... even if you're using $1500 apiece fiber or SAS drives.
