Is there a raid controller build in

I'm running a powermac g4 Mdd and i wanted to know if there is a raid controller build into it.  I've never done a raid but i'm told it could make my system run faster.  I plan to do a raid 10 because i have 4 drives.

Disk Utility provides the means for configuring a software RAID only.

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?
Do You Really Need a RAID?
There is only one thing a RAID  provides - more space.  Beyond that a RAID can’t help you with:
Accidental deletion or user error
Viruses or malware
Theft or catastrophic damage
Data corruption due to other failed hardware or power loss
Striped RAIDs have a higher failure risk than a single drive
The purpose of a RAID is to provide high speed mass storage for specialized needs like video editing, working with extremely large files, and storing huge amounts of data.
If your array fails it means complete loss of data and hours of time to rebuild.  RAIDs degrade over time necessitating many hours of restoration.  And, if you don't know much about RAIDs then you really don't need one.
You can use a RAID for backup.  But unless your backup needs involve TBs of data requiring rapid and frequent access, why bother?  TM works in the background.  It's not like you have to sit there waiting for your backup to be completed.  Furthermore, you're buying two drives possibly to solve a problem where a single drive will do.  And, one drive is less expensive than two.
Ignoring overhead, two drives in a RAID 0 (striped) array should perform about twice as fast. However, as the array fills up with files that performance will degrade.
RAID was a technology that in it's time was meant to solve a problem.  Large capacity, fast drives were extremely expensive.  Small drives were cheaper but slower.  However, combining these cheaper drives into arrays gave faster performance and the larger capacity needed for data storage needs.  Thus, the reason why it's called Redundant Array of Inexpensive Drives.  But today you can buy a 3 TB drive with performance that's better than the 1 TB drives of two or three years ago.
But why trust your boot drive to a RAID?  I certainly wouldn't.

  • C-220M3 RAID controller

    Hello,
    Cisco people has told me C-220M3 has to mandatory bring a RAID controller in it if you configure one HDD...actually Dynamic Configuration Tool doesn't let me configure a C220M3 server with one HDD if I don't add a RAID controller. I'm trying to find a technical explanation for that...as I recall, the old C-200M2 can be configured with one HDD and without any RAID controller at all, and that doesn't pose any problems.
    Any inputs on that?
    Thanks,

    Hi Dani,
    the C200 server has a in-build RAID controller which you could use. However on a C220 there are no similar integrated modules available and you need to choose either a mezz or a PCI (LSI) RAID controller for RAID configuration.
    here is the chapter from the configuration guide:
    http://www.cisco.com/en/US/docs/unified_computing/ucs/c/hw/C220/install/raid.html

  • Intel(R) ESB2 SATA RAID Controller not working out of the box

    Dear all,
    I'm using, for my tests, an old server with a supermicro X7DBN Server motherboard.
    This motherboard comes with an embedded Intel(R) ESB2 SATA RAID Controller.
    When I try a native installation from the technical preview DVD it sees the RAID1 volume that has been created (2 disk mirror) but when I select it to proceed with the installation there is an unknown error stating that it's impossible to write to this disk.
    The same installation works perfectly with 2012R2 and the out of the box driver provided bin the install media.
    An update from the previously installed 2012R2 to the Windows Server Technical Preview also works without problem.
    It would make sens for MS to revert to the driver version embedded in 2012R2 for Intel(R) ESB2 SATA RAID Controller which is:
    Name : Intel(R) ESB2 SATA RAID Controller
    Date : 10.08.2010
    Version : 8.6.2.1025
    inf section : iaStor_Inst_RAID
    Device ID : PCI\VEN_8086&DEV_2682&CC_0104

    Hi,
    Thank you for the information. As you said from the behavior it seems that the build-in drivers of Windows Server Technical Preview will not work with the specific motherboard hence the RAID1 cannot work well. 
    I'll log the issue down. 
    If you have any feedback on our support, please send to [email protected]

  • MSI K9N2 Diamond 780a & On Board Raid Controller

    So like to know anyone would know why Raid 0 setup with 4 Seagate ST3250410AS would have get corrupted BOOTMGR & BCD after few day on idle time. Since I build this system with pair of 9800Gx2 and AMD 955, always had issue with the raid. Just to be getting worst over time. System seem to crash out and this is a clean install of Window 7 64bit with nothing but drivers. Reboot, show only channel 2 SATA drive failed and sit there waiting for me to fix it. Now every drive been tested and two have been replace by Seagate to to rule out two drives. No matter what drive in channel 2 SATA still will fail on that channel. I've already replaced cables on the drive, nothing change it. Seagate no longer willing to work with me saying Nvidia issue. MSI wont support board seeing no longer being made. Video card, CPU, Motherboard all have been replace this year under RMA. So seeing there new parts and clean OS, I can't think of anything on top of my head that would cause this.
    Love to know anyone else as had problems with this chipset or think of idea to try.

    PSU maybe?  What kind of device are you using (brand & model name)?
    If it was PSU, would have lot more issue than Raid.

    One of the drives gone bad?
    As stated dosen't matter which of the drives are in channel 2 Sata, it always fail on that channel. All drives been tested, two were replace by Seagate just because I felt they were bad. Had +20k hours on them. Once you power down, the array would come back to normal.
    Quote from: Fredrik on 02-December-10, 21:51:57
    Yeah. Just a thought, are they all jumpered the same? Try SATA 1. And we know Windows 7 has had issues with RAID 0 setups before, so go search for an updated driver.
    Lulz, Nvidia hasn't update there drivers since last year. So there no update for 780a chipset. I run a 4 drive setup on MSI 890FX been fine to this day. Seeing only happen when the system in idle, I've believing there some power management kicking in on the chipset, even so I have power profile set to "always" on everything. 
    I'm to that point were dropping all Nvidia support in my shop. Since 590SLI boards there as been bug and bug with all there chipset and video cards.
    Hybrid SLI - (Only Issue In High Clock RAM) 
    GeForce Boost
    590, 680a, 750a, 780a Raid Issue ( got 6 boxes of good motherboard, that I had to replace out because Raid controller.
    Driver for 196.75 stop some video cards fan, took my 9800GX2 and got 2 8800GT, and 9800GTX+ that failed in other builds from that update.
    Mobile GPU issue since GeForce 8xxx line, just ask HP, Apple, and my 9800m GTS, 480m GTX SLI setup.
    Dropping support holder, as we all know BFG and XFX no longer have Nvidia video cards. BFG lost sales over OEM video cards and killed company. XFX started to sell ATI base, then Nvidia wouldn't sell them new Fremi cards. I'm glad I only put MSI video cards in all system I've built for myself and other. BFG no longer up holding to the warranty on there cards. 
    More work than I need ~sigh~

  • Hard drive configuration with Promise Raid controller

    I plan on running two 30 gig 75GXP drives on the Promise controller in Raid-0 mode.  I also have a 60 gig WD drive that I use for backups and for initial installation.  During installation, I put the Win98SE setup files and all the drivers, apps, backup data, etc. on the WD drive and do a clean install from there.  
    My current (old) board is an Abit KT7-R with the Highpoint raid controller.  Using the Highpoint controller, I am able to put the WD drive as a slave device and the controller treats it as a normal IDE drive.  I'm moving to the 845 Ultra ARU.  From what I've read, if you put a single drive on the Promise controller, it tries to set it up as a Raid drive?  I don't want to risk losing my backup data on the WD drive to some attempt by the Promise controller to "raid" my single drive.  So, where is the best place to put my WD drive so that I can install my system from it?  I'm thinking about putting it as Master on IDE2.  I normally run my CD as Master on IDE1.  Once the installation is complete, I will remove the installation files from the WD drive and use it exclusively for backups.  I have the WD drive in a Vantec EZ-Swap rack, and I normally keep it powered off unless doing a backup.
    So, the plan is to create the Raid-0 array, Fdisk and format the array, and then load Windows from the WD drive, followed by all my applications.  Is Master on IDE-2 the best solution for the WD drive?  

    hi
    not very clued up on raid but it sounds right
    if the wd drive is on its own on that ide do not jumper
    as master you have to have no jumpers if all alone

  • Unknown Raid 5 Array after Raid controller replaced

    Hello,
    I had a raid controller fail during the week, and after shutting the xraid down and installing the new controller, all the drives in the array are now amber.
    In Raid Admin 1.5 the array does not show up, only all 6 member drives with an amber warning and 'Type: Unknown Array'.
    I used the 'Recognize Array' utility to try and fix this, however whilst each drive shows as being recognized as being part of a Raid 5 set, it will not recreate it.
    Am I completely screwed? or is there some other way to get this to repair/recognize?
    Any tips would be greatly appreciated.
    Thanks
    Mark

    Due to time restrictions on getting the xraid back online, had to recreate the raid and restore data from backup.
    No fix found.

  • Shopping For A RAID Controller

    I have seen the Areca brand name on here many times, so I assume they are the best for what we do. But, there are so many models that I have no idea what to look for. I probably won't ever have more than 4 or 6 storage drives plus an SSD system drive. Maybe a couple of external drives and an NAS.
    If I have Windows 7 64-bit
    i7-2600k processor
    ASUS P8P67 Pro motherboard
    32 GB RAM 1600
    GeForce GTX 580 Amp! from Zotac
    AX850 PSU from Corsair
    Every component is reasonably fast, bu I am sick of the senseless limitations of this mootherboard. My drives are aging so they need to be replaced.
    Which specs are important for video editing? Which brand and models are most popular and shoould I wait for some new release?
    Another thought - If a RAID controller is over $400 US, Is it more cost-effective to upgrade to a more capable motherboard/processor with all the ports I need?

    What to look for
    Brand
    Areca or LSI
    Ports
    8 or more
    Card
    PCIe-3.0 8x
    Cache
    512 MB or more
    Multi-lane
    SFF-8087/8088
    Examples
    Areca ARC-1882 series or LSI MegaRAID 9285
    Warning: You have to realize that on your motherboard adding a dedicated raid controller will entail that your video card will throttle down from PCIe-16x to PCIe-8x mode, resulting in a 10 - 15% performance penalty, due to limitations of the chipset. A dedicated raid controller, especially with around 6 disks always outperforms an on-board raid by a wide margin. To see some benchmark results, look here:  Reflections
    To see what meets your requirements, also consider the raid level you want to use. If raid3 or raid30, then LSI is out. You can check out what controllers are popular here: Detailed Results but you have to be registered and logged in to access the page.

  • K8N master2-far doesn't detect Areca 1220 raid controller

    Today i purchased the last components for my system. Everything works perfectly except for my Areca 1220 8x pci-e raid controller. As i feared the controller is nowhere to be seen, not in the bios, not in windows. I already had bios version v1.10 but flashed the bios version on the msi site anyway. Nothing changed. On the msi site under "QVL" i see my Areca at the bottom of the list. Does that mean that this MB can work with this controller? What must i do to make it work? I think i have to see it at least in the bios!
    Your help is appreciated. Now 5x 300 GB of storage is doing nothing.
     

    Quote from: Bas on 10-November-05, 20:30:00
    Maybe you need to update the cards firmware.
    I already looked into that matter and found out that the only way to upgrade the firmware or bios is to use their http tool McRAID Storage Manager. This of course is done in windows. Now windows doesn't see my Areca 1200 and so McRAID doesn't see it either. I can't update my Areca.
    This problem is well known by the motherboard manufacturers. Let me quote something from the Areca site:
    Q10150407 - Is there any socket 939 motherboards that work with your model ARC-1210 raid controller? In a SLI board I would use one 16x slot for Graphics card.
    Our PCIe ARC-12xx series controller uses Intel IOP332/333 processor. The Intel high performance IOP (IOP331/332/333) has integrated the bridge chip in the controller. But the original NVIDIA nForce4 SLI chipset BIOS has the problem after Bridge IRQ routing. All controllers use Intel new IOP 332/333, such as Areca, Intel, and LSI have the same IRQ routing problem. Those NVIDIA 939 M/Bs can be worked in the Windows environment. Due to the Windows system takes over the BIOS job, and Linux & FreeBSD need to use the M/B BIOS, so it has problem with our PCIe controller.
    Currently, DFI, Ausu, MSI and Gigabyte have BIOS to solve the problem. If you have problem in this kind of mainboard, please try to manufacture latest BIOS.
    We have tested DFI Lanparty NF4 SLI & ASUS A8N-SLI Deluxe, and Asus A8N-SLI Premium. It works very well with our firmware 1.38 and newest mainboard BIOS. Try to swap the graphic and our controller, if you find some warm boot problem in the Asus A8N-SLI Premium.
    I still think i need an updated bios for the k8n master2-far (ms-9620). The fact remains that there are problems reported with every SLI motherboard. I knew this already from the socket 939 platforms. I was sceptical about the k8n master2-far but thought that a server MB should have no problems. I did ask a question about this however at the shop where i bought this MB. I even found an reply from you to another user who had similar concerns about the Areca controllers and an SLI MB. You said that it should not be a problem. Even so i always kept the possibily open that this problem can happen. And here i am 
    Thanks for your help. More input is always appreciated as i am still waiting for an answer from MSI in the Netherlands about this problem. Right now my server is doing nothing. I hope my raid controller will work very soon.

  • Cannot boot with Perc /2 raid controller

    I have just built a system with K7D + 2 2400 MP, and the system hangs when I try to boot with my Perc/2 raid controller in. I have stripped down to just the following components;
    2 2400 MP
    Perc 2
    1GB ECC ram
    Sapphire ATI Radeon 9000
    When I try to boot the machine it gets as far as trying to load the Perc /2 Bios and hangs.
    The Perc works fine in my old system Tyan Tiger 133 with dual 733 PIII, it also seems to boot up fine in a Tyan Tiger S2460.
    Any ideas on the cause or a work around?
    Thanks.

    Yeah, all the firmware & bios is up to date, have stripped things down to just the motherboard, graphics card & Perc. Tried PCI graphics to elliminate any conflicts there. I have disabled all the on-board controllers too.

  • "Update for raid controller firmware" in availabel system upgrade does not go away after upgrade

    We have two Ironport WSA, one S360 and one S370. Both stil have the "Update for raid controller firmware" still listed in "Available upgrades" even though we have done the update and rebooted the appliances.
    How can we confirm that the update is applied?
    If it is and the notice is still there how do we get rid of the reminder?

    Go to the command line of the appliacne and run "version"
    That will show you the current version of the firmware.
    If you have record of what was there, you can compare...
    Otherwise contact TAC, they can verify that you have the up-to-date version and pull your serial from the distribution list so you don't see it any more.

    I have tried to move the card to another port with no luck.Ran all the updated software possible. Please can someone advice

    Hi,
    Was the card previously working in that machine? If it was and you have a G5 tower you could try the card in there. Here is a list of Apple fibre cards and cables which show what's compatible with what. http://support.apple.com/kb/HT1769
    The card should appear in the System Profiler under Fibre Channel and PCI Cards.

  • RAID Controller for V890

    Hi,
    I was wondering if anyone can tell me whether there is a RAID controller available for V890 for its internal FC-AL hard disks. I've never seen a RAID controller for FC hard disks and my vendor claims that there is no RAID controller available for the V890. So many hard disk slots & no RAID controller doesnt seem like the best of ideas. Software RAID just doesnt cut it when u apply RAID 5 on this number of hard disks.
    Regards

    Hello There,
    There is no RAID Controller available to be used internaly for V880/890.

  • KT4 Ultra (6590) need update of the Promise SATA RAID Controller PDC20376

    The last Bios update AMI 1.4 for the KT4 Ultra (6590) have built in the bios version 1.00.0.18 for the PDC20376 (Promise 376).
    I can configure 2 maxtor (6E040T0) sata1 in a raid0 array and it works under WinXP SP3,
    but the 2 drives are working in UDMA5 according to the FastBuild Utility when the motherboard specifications talks about 150Mb (SATA1).
    It's not an OS problem because the FastBuild Utility at Bios startup show the UDMA5 mode for HDD.
    It's not a Maxtor 6E040T0 (SATA1) problem because have no jumper to set.
    The Promise support center don't provide support for built in raid controller but the responce was that it's related to a known bios issue of the controller, so i have to update.
    For the last Bios version for the S150 TX4 controller look at:
    http://promise.com/support/download/download2_eng.asp?productId=108&category=all&os=100&go=GO
    It's impossible to update the bios with the promise tool because the controller is integrated in the motherboard.
    I read for example than on the motherboard K7N2 Delta-ILSR the bios version of the Promise 376 controller is 1.00.0.21:
    https://forum-en.msi.com/index.php?topic=92756.msg665966#msg665966
    I think the only solution is a modding bios, where i have to replace only the Promise controller bios but:
    1) The tool amibcp.exe can't open the A6590VMS.140 AMI bios (renamed .rom), i don't know why!!!
    2) What promise controller bios rom file is good?
    Can anyone out there help . . . please ?

    This is my results compared to my other UDMA6 HDD on IDE1, HDTach long bench stop with "Read Error" and only quick bench works.
    The version of the Controller driver under WinXP-SP3 is 1.0.1.29 and I configured the driver in the PAM Utility with:
    "Driver Write Cache" enabled and "Write Back" as cache settings (The 2 Maxtor SATA1 in RAID have 2MB of cache, but i don't know How many cache have the controller!!).
    The Burst Speed is too strange!!! quick bench error?

  • Where can I find Event Log ID's, produced by Intel ICH9R RAID controller on Windows Server 2003?

    I need to monitor RAID errors and events by parsing Event Log, but I need a list of possible errors that I can find in event log. I'm using Intel ICH9R RAID controller. Server manufacturer (SuperMicro) said, that errors, produced by controller, are interpreted
    by Winows and than are put to Event Log, so I need to find this info somewhere else.

    Hi,
    As far as I know, there isn’t such as list present those Event Log ID’s for Intel ICH9R RAID controller, you may contact Intel to perform
    the further research, you may also wait for other customer's experience sharing on this.
    By the way, based on my experience, most of the IT guys will use the monitor application/toolkit comes with the RAID controller, so you may contact Intel
    also to get more information. Thanks for your understanding.

  • Hardware RAID Controller

    Hello,
    Can someone tell me if there is ANY available RAID controller for Sparc platform, specifically E servers? I can't find anything anywhere on this, but it seems such a gaping hole I'm surely missing something. Anything equivalent to the myriad of controllers available from Adaptec, Compaq, Mylex, etc. on Intel? 3-rd party maybe?
    thx

    Which "E server"? Sun sells the SRC/P RAID controller
    on a PCI card. It was not qualified on all servers, so
    it is difficult to answer your question specifically.
