V65x RAID 1 and RAID 5

My query is lets assume I have 5 hardisks in the V65x server I would like to configure the first two hardisks as RAID 1(Mirror) rest three Hardisks as RAID 5 with REDHAT Linux as OS
i would like to know is it possible? does the V65x server support this feature ? which SCSI card is support buy V65x and REDHAT v?
Your valuble info will be of great help ...

Lookout has not shown issues for any system we have had using RAID 0,1, 1+0, and 5.
Good luck,

  • General HELP for RAID and HOME NETWORK... I'm a bit lost :(

    First off, I'm sorry about the long post but I just wanted to ask everything at once since I don't know what effects what?
    Over the past years I've had a MBP and have always added Western Digital Mybook drives whenever I needed storage. One of clicked and died this past year and I lost some data since I was "MANUALLY" backing up. Since then I've tried to read about RAID, NAS, and DROBO type devices.
    I recently bought a Mac Pro 2008 edition because I needed more speed. I mainly edit wedding photos in Lightroom but also come from a heavy motion graphics background and do some After Effects projects from time to time.
    Here's a list of my current setup and what I'm hoping to achieve but I'm in over my head of what to do???
    1 Mac Pro (2008 edition) - I'm considering setting up 4 1TB harddrives inside that are mirrored. I was looking at the Caviar Black or Hitachi drives...
    2. I have two Airport Extreme Base Stations for my home network. (One is plugged into my Mac Pro and the other is near my Vizio LCD and Xbox 360. I've been toying around with sharing iPhoto slideshows (which I really like the idea of) The problem is that it seems really slow for video and hiccups on the stills sometimes. It doesn't seem to make a difference if it's pulling it from the Mac Pro or from a USB drive attached directly to my Airport Extreme. How do I speed this up? Is it always going to be faster to stream from the Mac Pro over ethernet cable than a harddrive plugged in through USB?
    3. A few RAID and NAS solutions I've been looking at are the following but I don't really understand what I get with an external device vs an internal? I also don't know which is BETTER? for easy reliable backup.

    4. I've been reading mixed reviews about the Drobo but don't quite understand if it's a better solution then setting up a mirror INSIDE my Mac Pro. I DO NOT want to buy a $900 raid card for the Mac Pro though. Do most people choose the Drobo because they only have laptops? Should I only consider building something inside my Mac Pro?
    5. I was considering Chonosync for backing up 3rd level backups
    6. I just bought a Blu-Ray drive for 4th level backups that I can send off site.
    7. I have all these other Mybooks. Two of them are mirrored but only one is a 1TBx2 Sata drive. The rest are IDE. I guess I'll just use these for misc things? Maybe just plug one into the Xbox for watching movies?
    8. My neighbor down the hall has a similar setup and is using a Mac Mini to stream things (through Front Row) like Hulu and videos another room to his TV. Mine doesn't seem to stream fast enough. Since I have the MBP that I will use rarely since I got my desktop I was considering using that instead of Apple TV or a Mac Mini but it's too slow? Maybe I set it up wrong?
    PLEASE HELP? I don't know what I'm doing.

    Hi,
    For backup, video work, photography and expanding the Mac Pro storage capability the FirmTek SeriTek/5PM would be my choice. The bundle that you pointed to will work if 130MB/sec. is fastest enogh for your needs. The card is only $70 in the bundle which makes it a nice deal.
    http://firmtek.stores.yahoo.net/sata5pm2se2.html
    If you want 200MB/sec, performance I would go with the Sonnet Tempo E4P or the HighPoint RR 2314 if you desire RAID 5 redundancy.
    http://www.amug.org/amug-web/html/amug/reviews/articles/sonnet/mac-pro/
    http://www.amug.org/amug-web/html/amug/reviews/articles/highpoint/2314/
    Trying to use NAS via the network will be 3-7x slower than the SeriTek/5PM. The SeriTek/5PM is a much better choice for backup, video and photography. NAS is good for low energy, always on, low use server needs. However, you can simply turn Mac OS X file sharing on and the Mac Pro will provide performance faster than any NAS.
    Drobo - Why do people even consider this option?
    The performance is USB speed even with a FW800 connection.
    Users have reported losing data with firmware updates.
    And the unit is one of the most expensive, slow performing options available. I cannot image ever wanting a Drobo
    Backup Software:
    I like SuperDuper. I also like using the "Restore" tab in Disk Utility to clone one disk to another. The key to good backup is to keep it simple and regular.
    MyBook - NOT
    If your storage needs exceed more than a single FireWire backup disk you really need to go with eSATA. The SeriTek/5PM and the Mac Pro combination provides virtually unlimited storage capabilities as the tray system allows new hard disk sets to be easily loaded or dismounted.
    Have fun!

  • 975x and Raid .. Works fine for me with all bios

    I just glanced at the Bios thread to look something up (I forget what) and was stunned to see the posts there...
    Why are people being discouraged from using Raid with the Official bios ver 7.3 (or any other bios) ?
    If there was a problem using Raid with an official bios, especially one that gets auto updated, this board would be swamped with complaints..
    I have never had a problem with Raid on this board..
    And most of you that know me, know that I test almost every bios that comes out..
    I don't have to reinstall my raid after installing a new bios...
    Okay... sorry .. had to rant...
    I don't have a step by step of "how I set up my Raid" but basically here is what I did..
    (Please note, everyone has their own prefered method for installing an OS on a raid)
    No matter what bios I used, I would have my "working" OS on an IDE drive...
    I would then reboot, go into my bios, set my Sata to Raid (set forcegen to whatever you want)
    f10 to save the setting and when the reboot happens, I try "control + I" to get into the Intel panel..
    If I don't get the Intel Panel, I just reboot again, go in the bios, disable jmicron (my IDE drive will still work), and ...
    f10 to save setting, and try "control + I" to get into the intel raid panel, if you can't get into the panel, something else is set wrong in your bios or your SATA drives aren't set up properly..
    Once I created my raid, I would boot into my OS (on my IDE drive)...
    My OS will find the raid and want to install a driver, ignore that, and just install the Intel Raid software..
    Then I would either migrate my OS to the newly formed Raid drive using a tool like Data Lifeguard (that is Western Digital's tool for its drives)
    Or I would just restore to the raid drive using an OS backup (I used Norton Ghost) and set the Raid drive as a boot drive..
    Make sure your raid is formatted as a "primary partition" to be a boot drive...
    Now that I have my OS on the raid drive, I just simply reboot, go into my bios, set my raid as the first boot drive and then when my system boots, I am running off my Raid...
    As for having my raid running and trying a new bios...
    I just flashed from bios ver 7.30 to ver 7.16 booted into my raid (all worked fine) and then flashed back to 7.30 and no problems finding my raid...
    The only suggestion that I can offer is:
    If you have problems finding your SATA Raid after a bios flash, the problem is most likely jmicron related...
    Try disabling the jmicron in the bios (your IDE stuff should work fine unless you are using a Raid on the jmicron ports)..
    or just try disconnecting all your drives except your SATA raid
    Then see if you can see your SATA raid...
    Understand, if there was a problem with running raids with this motherboard, there would be posts everywhere..
    Somehow, either the way you created your raids, your bios settings, or the way your jmicron is implemented is causing problems..
    Hope this helps someone...
    I know I am gonna get blasted for this post...
    But I don't think I am the only one running a SATA raid using bios ver 7.3
    I just think that those with working Raids, don't look at the Official Raid thread since it looks like a "How to" thread...
    I am sorry (in advance) if I offended anyone with this thread...

     
    Hey Vaniireq
    1. Thanks for that info - Perhaps the forum modrerators would see more of the issues coming to light with RAID if they changed the topic in the stickies from HOW TO install Intel Matrix Storage Driver Guide  to MAIN RAID ISSUES and put in a subthread on HOW TO install Intel Matrix Storage Driver Guide
    2.  I have always kept the JMD disabled as nothing on BIOS 7.1 would work for me in raid when otherwise.
    SUGGESTION:  I suspect that many when starting to look at the forum have no idea what there is in the "HOW TO install Intel Matrix Storage Driver Guide " thread - as it does not mention RAID that clearly.
    Just a suggestion.   
    I am about to do the 4 hour check and attempt to get back to dual channel 800 with my system.  Will advise....
    Good weekend all.........  Keith

  • Clean installation of Win 7 using UEFI and RAID

    Hi,
    I am trying to perform a clean UEFI installation of Windows 7 with SATA mode switched to RAID. I have two identical HDDs for RAID and 80 GB Intel 310 to put the OS on. The BIOS/UEFI can see all 3 drives and the two HDDs are configured for RAID through the CTRL-I utility
    When I start the Windows 7 installation, it does not find any hard drives and prompts me to load mass storage driver. I tried loading Intel Rapid Storage Technology drivers through USB flash drive, and the installation correctly displays "Intel(R) Mobile Express Chipset SATA RAID Controller", but after couple of seconds of loading when I click on Next, it comes back with the same result, no drives found.
    I tried switching SATA mode to AHCI and the installation recognizes all 3 hard drives just fine.
    Any help would be greatly appreciated.

    The BIOS to fix this issue has been released.

  • 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!

  • Mac Pro RAID and Boot Camp and eSATA controller Card

    Hello all,
    I have carefully read the topics concerning the Apple RAID card and its inability to run Boot Camp. Of course, I read this after placing my order. I have been mulling over my alternatives based on everyone's input. Here is what I want to do and how I think I can get there:
    My system, when it finally arrives and is assembled will be:
    Mac Pro 3.2GHz
    12MG RAM
    4 x 1TB hard drives
    Apple RAID Card
    ATI 2600
    Except for the RAID card, the memory and drives are third party.
    My plan was to create a RAID 5 with 3 of the internal drives, with the OS and apps on the non-RAIDed drive. I wanted to install Windows in a Boot Camp partition, but since learned this is not possible with the Apple card. I also planned on using the OWC Mercury Elite RAIDs I have (each enclosure house 2 x 500GB drives, and I have 4 enclosures for a possible max of 4TB of back up) to handle Time Machine (or other BU strategy) for the internals.
    I have not received the Mac yet, so cannot look inside. From what I can gather, the Graphics card will occupy the Slot 1. The Raid Card will occupy Slot 4. This leaves me with only one 4x slot for a 4 port eSATA controller card (such as the RocketRAID 2314)
    As I see it, I have a couple of obstacles to overcome, and I would appreciate advice/feedback on my possible solutions.
    Problem 1: In order to use my existing OWC RAID enclosures, I need TWO controller cards, each with 4 eSATA connectors. Unless I scrap the 500GB drives for 1TB drives, I am stuck. Am I correct in assuming I cannot use Slot 2 for another controller card? Is there any work around?
    Problem 2: Boot Camp. Can I purchase the Newer Technology extender cable to access the two eSATA ports on the Mac's motherboard to attach an external SATA drive for this purpose?
    Questions:
    1) I assume I can set up an external RAID (another RAID 5?) with my OWC drives and use Time Machine to back up to them?
    2) From the illustration in the Mac Pro manual I downloaded, there appear to be only 4 PCIe slots, but 5 openings (one seems to be aligned with the back-up battery). I assume this is the double-wide space for the graphics card. Can I use the extra opening for the Newer Tech ports since there is no card taking up space?
    3) Should I remove the Apple RAID card (resell on ebay) and buy the CalDigit RAID Card? It has the virture of allowing a Boot Camp install AND has ports that I can buy SAS to eSATA cables for, allowing me to use all of my OWC drives.
    The CalDigit Card sounds good, but I would like to make the Apple card work if I can. Also, with the OPTIONAL battery back-up, the CalDigit card isn't that much less than the Apple card. Besides, I cannot find this card anywhere, everyone's at NAB, and it's Passover next week. AND I need to get this system up and running ASAP so I can begin making the money to pay for it.
    Any input would be most welcome.
    Gary

    Problem 1: In order to use my existing OWC RAID enclosures, I need TWO controller cards, each with 4 eSATA connectors. Unless I scrap the 500GB drives for 1TB drives, I am stuck.
    You could get new enclosures with SATA port multipliers for up to five drives per SATA port.
    Am I correct in assuming I cannot use Slot 2 for another controller card? Is there any work around?
    Apple says any PCI-e card should work in slot 2
    <http://developer.apple.com/documentation/Hardware/Conceptual/HWtechPCI/Articles/pciimplementation.html#>
    "Mac Pro detects whether an inserted card is PCIe 2.0 (5.0 GHz) or PCIe (2.5 GHz) and selects the operation depending on the card's maximum capability."
    but there have been reports of trouble (maybe caused by the recent firmware update). Check with the card maker to be sure.
    Problem 2: Boot Camp. Can I purchase the Newer Technology extender cable to access the two eSATA ports on the Mac's motherboard to attach an external SATA drive for this purpose?
    No. Those ports are only usable from OSX, but if you only have one optical drive, you can mount another drive in the lower optical drive bay with a Pro Caddy for use with Boot Camp.
    <http://www.transintl.com/store/category.cfm?Category=2704&RequestTimeOut=500>
    This simplest connection is to use the optical ATA cable (with a SATA to ATA adapter for a SATA drive).
    If you want to use a SATA connection, use a iPass to SATA cable from the iPass port on the Mac Pro logic board, which is normally used for the four SATA drives when there is no RAID card.
    <http://www.pcconnection.com/IPA/Shop/Product/Detail.htm?sku=7252016>
    Questions:
    1) I assume I can set up an external RAID (another RAID 5?) with my OWC drives and use Time Machine to back up to them?
    Yes
    2) From the illustration in the Mac Pro manual I downloaded, there appear to be only 4 PCIe slots, but 5 openings (one seems to be aligned with the back-up battery). I assume this is the double-wide space for the graphics card. Can I use the extra opening for the Newer Tech ports since there is no card taking up space?
    It looks like it should work if you route the cables just above the graphics card.

  • Problems with RAID and a Flash USB Drive

    I'm attempting to install on a RAID 1 array using just one usb flash drive.  Yes, just one.  I'm trying out the idea's in this thread: http://bbs.archlinux.org/viewtopic.php?id=64281
    Partitioning scheme:
    sdb1 -> boot partition
    sdb2 -> swap
    sdb3 -> raid 1 array -> root
    I set the partitiions to type 0xfd (linux raid autodetect) in fdisk (probably not necessary) and created the array with:
    mdadm -C /dev/md0 -n 2 -l -b internal missing -W --write-behind /dev/sdb3
    I then installed like normal, specifying that I needed usb and raid hooks in mkinitcpio.conf
    I added "md=0,/dev/sdb3" as a kernel option in grub's menu.lst, specifying that the md driver should assemble /dev/md0 (my root partition) out of /dev/sdb3 before trying to mount it.
    This process was succesful using a partition on my hard drive.
    However, using a usb drive causes a kernel panic during boot when trying to mount /dev/md0.
    Looking at the messages reveals that before my usb drive was detected, md attempted to create the array, unsuccessfully, as /dev/sdb didn't exist yet.  "md: unkown device name /dev/sdb3" or something to that effect.
    In mkinitcpio.conf, the usb hook comes before the raid hook, so this shouldn't be happening, should it?

    I think rootdelay will not work in that special case, rootdelay makes the system to wait after all the hooks are executed, and you need to wait before executing the raid hook.
    I don't know if there is an easy way for that, but one solution is to modify the raid hook to wait for /dev/sdb3 to be created :
    - edit /lib/initcpio/hooks/raid, add this before the /bin/mdassemble command :
    until [ -e /dev/sdb3 ] ;
    do
    sleep 1 ;
    done
    - rebuild your boot images with mkinitcpio (you'll need to chroot to your system)
    that should work
    PS: someone correct me if I'm wrong, but from what I know, the usb hook does not create your /dev/sdb (if you edit the usb hook, you'll see that it only set rootdelay if it is not yet set). it is the udev daemon, which is launched in the background by the udev hook, and the udev daemon is quite long to create USB device nodes.

  • How to install the driver of the 'SCSI and RAID Host Controller'

    Hi,
    I have two Windows XP(32Bit) installations:
    •Windows XP SP2(32Bit) which is old and it seems as if it is infected by some viruses.
    •I have installed another fresh clean Windows XP(32Bit) SP3. However, I have found that there is no category named with ''SCSI and RAID Host Controller'. However, when checking out the old version of Windows XP, I found  'SCSI and RAID Host Controller'
    is there. (Screen shot below)
    The new Windows XP(32Bit) SP3, there is no 'SCSI and RAID Host Controller'
    My motherboard is:
    My Desktop Computer(Intel P 4, 512MB of RAM, and Graphics Card  with 256MB of RAM.
    ]I am seeing that most computer doesn't has the scsi / raid controller . in the old Windows XP on my computer that SCSI and RAID controller exists, and it it has not  a yellow mark on it.
    When I installed  a new windwos XP 32Bit SP3, no SCSI/RAID in divice manager .
    My computer sound on new Windows XP doesn't work , however, on old Windows XP SP2 works well. I have a buitl-in  sound card. SCSI and RAID controller category in the device manager on the old Windows xp SP2 is realted to sound card,I don't think.
    Thus, What drivers would let the 'SCSI and RAID Host Controller' added in the device manager?
    A man should convert his anger and sadness into strength to continue living in this life.

    If you open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on the pcb somewhere. You should also normally see this information on the first POST screen when you turn on the PC.
    Otherwise Google "775i65G" like I did.
    Here are the driver downloads (assuming it is an Asrock 775i65G R2.0 and not an R3.0)
    http://www.asrock.com/mb/Intel/775i65G%20R2.0/?cat=Download&os=XP
    You should install the inf driver first. Hopefully after you do that you will see your desired listing in Device Manager.
    With regard to the AMR driver and the HDMR driver, you can find some information about these here :
    http://en.wikipedia.org/wiki/Audio/modem_riser
    Unless you actually have something plugged into these risers, it is probably not necessary to install the drivers.
    However, the drivers for the integrated C-Media audio chip and the Realtek Lan chip may prove useful.
    It looks like the motherboard has integrated video but if you are using a graphics card it will not normally be necessary to install the VGA driver.
    You can download both the manual and the installation guide here
    http://www.asrock.com/mb/Intel/775i65G/?cat=Manual
    And if "SCSI and RAID Host Controller" is still not shown in Device Manager, don't worry - because these functions are not supported by your motherboard (again assuming it is an Asrock 775i65G)
    Thanks a lot,
    First of all, when saying that I have multi-operationgs systems, I mean there are two operating systems installed on my PC(SP2, SP3) both are 32Bit. The first Windows SP2(NOT installed by me) has all multimedia audio card installed
    well, and has SCSI and RAID Host Controller shown the device manager. However, only the VGA is not installed on Windows SP2. However, the second one Windows SP3(Installed by me) has VGA not installed, Multimedia audio NOT installed, and there is no SCSI and
    RAID Host Controller in device manager.
    First: Why did the CPUz, specy didn't detect motherboard name, and only detect the model. IF I need to  open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on
    the pcb somewhere, then what benfit would be there from hardware detection software?
    Second: Yes, my motherboard has integrated video, and integrated audio card
    However, this doesn't mean that I don't need to install them since the Vidoe controller is not properly installed (it is a default VGA ) Also, Multimedia audio controller is not functiong at all.
    Finally: if And if "SCSI and RAID Host Controller" is still not shown in Device Manager in Windows XP SP3,  because these functions are not supported by my motherboard, then why is 'SCSI and RAID Host
    Controller' installed/shown in the device manger in Windows XP SP2 on the same PC???

  • How to GET RID of RAID and get back to IDE??

    Hi,
    I have a great Z800 Workstation with a 1.5TB HDD running Win7Pro-64. I've been using an 128GB SSD cache (Synapse/Dataplex) for about a year with no trouble, but stupidly thought that Intel's RST (Rapid Storage Technology) would do a better job, for writing in particular. So I installed RST... and run into touble.
    RST put the two disks into a RAID... but since the disks are not the same geometry, and I appear to have an old chipset, it never actually worked: RST was unable to create a cache (i.e. to accelerate the HDD with the SSD) and the SSD became useless, as its Dataplex conroller clashed with the RAID.
    In short, I would like to GET RID of the RAID (in view to replace the HDD by an SSD altogether)... but that appears to be impossible: I uninstalled RST and followed the "removdrv.txt" advice to switch (back) from RAID to IDE in the machine Setup... but Windows BSODs unless I keep RAID. Yes, I tried any and every "Repair" options Win7 could offer.
    So my question is: how can I get rid of the (fake/useless) RAID and get back to IDE?
    Many thanks for your advice!

    I have some bad news for you.
    If there is an actual RAID configuration present, then there is no turning back.
    Breaking a RAID set destroys data on the set and makes it unbootable. That is why you are seeing the BSOD. If you kep playing with it, eventually it won't even boot up in RAID.
    That means starting again from scratch with a new OS install.

  • Setting up a new raid and preserving disk contents

    I have a Maxtor 250GB drive full of data. I just purchased a Maxtor 300GB drive that I am going to use as a RAID 1. Is it possible to set up the raid without formatting the 250GB and immediately have it mirrored to the 300? If so, what steps would I take?
    Also can I set up two volumes on the 300 so that 250 is part of the raid and the extra 50 isn't?

    yes I noticed that but I travel a lot and want to have then stored on the Ipad so I don't use 3G data usage unknowingly..Its good in a way cause music you don't really listen to does not waste space...I did notice that if you select "album" view there is a choice to "download all" in that album so that would be faster then one by one..I would think they have a "download all" for the whole libary.

    Apple should add pixim in iphone's camera and raid technology too.
    Pixim will make iphone's camera perfect and raid technology will make it too fast

  • S20 - WD RE4 hdd compatibility and RAID 1

    I recently acquired an S20 and am looking to make good use of it. I am planning on using it as my home comp. I am intersted in two things:
    HDD compatibility - I am looking into the Western Digital RE series (non green) and wondering if these will work (2Tb each) since the RAID will require TLER (I've always used WD Black - this will be my first RAID setup)
    RAID 1 - Is this something setup in BIOS, Lenovo ware, or Win 7 (Pro or Ult). If I do get an adapter what is a good "inexpensive" (read: uesd/older) reliable brand model to use for a Raid 1? (This could also be moved later to a RAID 10 setup on a different project...maybe...)
    Okay...three...
    RAID 10 - Only with an adapter right? My original intended use of this unit was a home "Server"/"NAS"/'false hope that my data wont disappear" which I planned to use RAID 10...until I did my homework on the unit (3 bays). Would this units PSU be capable of handling this?  Even with a controller card am I still limited to <2.2Tb each or can I use up to 4-6Tb drives for this purpose only (only need 2Tb in the home comp scenario)?
    I'm not a business, I'm sure this is waaaay out of Warranty, I'm not concerned with anything other than will it work....

    welcome to the forum!
    RAID 1 is dead simple and can easily be handled by the built-in intel ICH10R controller.   TLER shouldn't be an issue.   i have two 2TB WD RED drives in RAID 1 in my C20 (on ICH10R) and haven't had an error or sync issue in two years.
    RAID 10 will be a problem for two reasons.   first, fitting four HDDs inside the S20 will be a mechanical challenge.   even if you could squeeze four inside the chassis, cooling will be a problem to this since RE4 drives are 7200RPM and run hotter than their lower RPM counterparts.   second, RAID 10 using four 2TB drives will create a 4TB array and won't be supported by the BIOS.   the largest size partition will be limited to ~2.2TB as you said.
    i would stick with RAID 1 and either look into external NAS or consider another system upgrade if/when you run out of storage space.   the 30-series and P-series systems are UEFI and support >2.2TB partitions.

  • On-board RAID and PCI RAID controller

    Hello everybody,
    I am new to the forum. So, please excuse me if that topic was already covered...
    I have MSI MAX2-LR (MS-6398E) board. It works just fine, no problem so far. Though I have 2 problems with add-on cards:
    1.  I was planning to use on-board RAID and additional PCI RAID controller = FastTrack 100 TX2 to cover 6 hard drives into 2 mirrored sets: 4drives one and 2 drives the other.
    It doesn't work! I can use either on-board RAID or PCI RAID. As soon as I have any drive connected to on-board RAID, the PCI RAID disappeares. If I have no drives connected to on-board RAID, I can see both RAID controllers, they have different I/O and IRQs, and PCI RAID is working just fine. If only I connect one drive to the on-board RAID, it gets activated on startup, and the other one disappeares. :O
    I believe it's a BIOS bug. I wander, if that can be fixed easily????? :D
    2. I have a new Matrox Video card = Parhelia. It doesn't work in AGP slot! System doesn't recognize it, and beeps non-stop. I am dealing with Matrox Tech Support on that matter.  ?(
    Maybe, it's a known issue, and somebody can save me time by telling what's that about.
    Appreciate any imput. Have a great weekend.!!! :]

    Hey I also have the same Raid card and also the Matrox Parhelia, and I see that you also have some problems with the card I got also problems with the card, but they couldnt help me at theire forums (http://forum.matrox.com/mgaforum/Forum10/HTML/005085.html), I hope we have got more luck here  :D

  • First try at a raid and CCC and have an issue?

    I recently bought 2 new 4tb seagate drives and an OWC elite pro dual inclosure with esata connections to back up my media files. For the last few years I've used a single drive for my media files and I've backed up that single drive with other single drives via CCC with no issues. I've had succes setting up the new stripped raid with the 2 4tb drives to create 1 8tb volume. However numerous tries to clone my single media drive to the raid using CCC have failed. The raid will unmount after 6 hours sometimes longer. Sometimes CCC will say there were problems with files. Today I reformated the raid back to 2 individual drives. I tried clonning my media drive to just one of the new drives in the new enclosure and it worked fine. I'm running the current version of mountain lion 10.8.4. So it seems to me that there seems to be an issue with the raid I'm setting up and mountain lion or maybe CCC. Anybody have any clue as to what's going on here? My next step is to try the 2 new drives in 2 of my mac pro's internal bays.....set up a raid again and try clonning that way. I was hoping to check in here first to see if someone knows what the issue may be first.
    Thanks

    This could be many things, doubtful it is hardware in itself as much as compatibility since each drive functions perfectly fine before the RAID. I would definitely download that driver. You mention energy saver preferences are off (ie unchecking 'Put hard disk to Sleep when Possible'), but keep in mind these preferences only apply to your bootable volume. The driver specifically addresses this issue.
    Also, just reading up online and in the forums, ML may be buggy when it comes to 2TB+ volumes (though in theory OSX could support 8EB of HFS+ formatted arrays!). Another option would be to purchase a program that would substitute for OSX native Disk Utility in handling large sized RAIDs:
    "Apple’s Disk Utility can be quite flaky with RAID and partitioning. It can crash and do other confusing things; you might have to repartition and/or delete volumes to restore drives to a basic state. For me however, it has never done anything bad to drives/volumes that it wasn’t already asked to operate on. I do not recommend Disk Utility for more complex RAID setups due to its bugs. Consider SoftRAID instead. "
    Download the driver first! Best of Luck.
