Discussion in 'Hardware' started by xyience, Dec 3, 2011.

  1. Hello,

    Meron kasi akong 8 20gig harddisk, paano ko po yun i-combine, i-setup yong RAID, ano po ang mga kailangan ko na hardware, anong klaseng controller ang kailangan kong bilihin, tapos anong software ang gamitin ko para i-combine ang 8 kong harddisk, para maging 160gig ang size.

    Pwede post nyo with pictures ang step by step kong paano i-configure/setup ang RAID.

    Salamat sa mag-reply, in advance.

    Intel RAID configurations - FAQ
    Revised November 14, 2011 - new IRST driver,

    Intel ICH7R,
    Intel ICH8R / ICH9R / ICH10R storage controller (the southbridge),
    Intel H67 Express / Intel P67 Express storage controllers,
    Intel Z68 Express storage controller

    The H67, P67 and Z68 controllers differ from the ICHxxR controllers by having 2 SATA 6Gb/s ports and 4 SATA 3Gb/s ports. The 6Gb/s ports can be combined with the 3Gb/s ports for a 2-6 drive RAID volume.

    RAID Array - the physical drives that contains the RAID volume(s).
    RAID Volume - the logical drive for the selected RAID level, 0, 1, 5, 10. The RAID volume will appear as a single Hard Drive, e.g. C:.

    If you want to run HDDs in RAID mode, either for the OS or for data storage only, you have to make that decision before installing the operating system. The BIOS setting 'Configure SATA as' ('SATA Configuration') has to be set to [RAID] before the OS is installed. It is not possible to change the default IDE mode, or AHCI mode, to RAID mode after the OS installation.
    At the time a RAID volume is created, it is possible to save space for a second RAID volume on the same RAID array by reducing the maximum size that has been filled in by default. The free space on the RAID array can only be used for creating another RAID volume. The second RAID volume must also use all drives in the RAID array.

    The 2TB limitation
    Due to a Microsoft limitation for MBR (Master Boot Record) drives, drives that are initialized as MBR drives, only sees the first 2TB of a larger drive and the rest of the drive is invisible and inaccessable.

    To create RAID volumes, or any partition for that matter, larger than 2TB, the HDD, or RAID volume, has to be initialized as GPT (GUID Partition Table). The theoretical maximum size for a GPT partition is 1048576TB. The main drawback with a GPT volume, is that the volume isn't bootable - unless the PC has an (U)EFI BIOS. (U)EFI stands for (Unified) Extensible Firmware Interface.

    This means that a RAID volume, hosting the OS (system), can not be larger than 2TB.

    GPT only applies to WinXP x64, Vista x64 SP1, Windows 7, Windows Server 2003 and Windows Server 2008 R2 (or later).

    (Another problem related to GPT partitions, is that in a dual boot configuration, both system drives has to be of the same type, normally MBR drives).

    The chipset itselfICH8R can host RAID volumes with a size up to 2TB.
    ICH9R and ICH10R can host RAID volumes with a size up to 256TB. A boot volume is limited to 2TB.
    The H67, P67 and Z68 chipsets can host RAID volumes up to 256TB.

    The 2.2+TB (3TB) limitation
    Only 10.5+ versions of Intel Rapid Storage Technology support 2.2+TB partitions for RAID.

    TRIM is supported in RAID and AHCI mode for drives that are not part of a RAID array (from Intel RST version
    RAID volume expansionThis only applies to RAID 0 and RAID 5 volumes. One or more drive(s) can be added to the RAID array, allowing a larger RAID volume.
    Supported by Intel Rapid Storage Technology on the following storage controllers:
    - ICH8R and ICH9R - No
    - ICH10R - Yes
    - H67, P67 and Z68 - Yes

    The expansion is performed at Add Disk within the utility Intel Rapid Storage Technology.
    Restore RAID mode after a CMOS reset
    When loading BIOS Defaults (F5), or when a CMOS Reset is performed, the BIOS setting 'Configure SATA as' ('SATA Configuration') reverts to the default AHCI or IDE mode. This setting should be set to [RAID] again before allowing the OS to start up.

    Can I create more than one RAID array on the ICH8R / ICH9R / ICH10R / H67 / P67 controller?
    Yes, you can create multiple RAID arrays. There are 6 sockets for connecting SATA drives, named SATA1-6 (port 0-5) on the ICH8R / ICH9R / ICH10R storage controller. On ICH8R and ICH9R, four are Red (bootable) SATA 1, 2, 5, 6, and two are Black (slave) SATA 3, 4 (port 2-3).
    All ports work the same in RAID (and AHCI) mode.

    If I've created a RAID array, then 'Configure SATA as' ('SATA Configuration') in BIOS would be set to [RAID]. Can I still combine that RAID array with single, Non-RAID, drives?
    Yes. Single, Non-RAID, drives will work in AHCI mode.

    Is it possible to connect a SATA Optical Drive to the ICH8R / ICH9R / ICH10R / H67 / P67 controller together with RAID arrays and possibly Non-RAID drives?
    Yes. The Optical Drive can be connected to either a Red (bootable) or Black (slave) socket, and you will be able to boot from it. The designations 'bootable' and 'slave' have no meaning in RAID and AHCI modes.

    Are there any special considerations to reflect on when I'm going to design my drive configuration?
    Yes, first of all you need do decide what you want to achieve. Are you looking for maximum performance, system security, data security (redundancy), maximum storage capacity or do you want everything? Well, you can't have everything, so you will have to make some decisions.
    There are several RAID levels, and I'm not going to describe them fully here, you can read about them in the User Guide.

    Here is a summary:

    RAID 0 (Stripe)
    Maximum performance and maximum storage capacity (at least two and a maximum of 4 drives (ICH8R) or 6 drives (ICH9R / ICH10R) are required). Disadvantage: With two drives, the MTBF (Mean Time Between Failures) will be half compared to a that of a single hard drive.

    RAID 1 (Mirror)
    Two identical disks are maintained for secure data storage. Storage capacity is the same as for one disk drive. Two drives are required.

    RAID 10 (Striping and mirroring, combines the functions of RAID 0 and RAID 1)
    Note that this is only one (1) RAID volume.
    Four drives are required.

    RAID 5 (Maximum redundancy and fault tolerance)
    Storage capacity as for the number of drives - 1 (one of the drives is used for parity data).
    A minimum of three drives are required. Maximum four drives on ICH8R, and six drives on ICH9R, ICH10R, H67 and P67.

    Intel Matrix RAID (sometimes called Matrix Storage)
    Makes it possible to create two RAID volumes on the same array of disks, for example a RAID 0 volume and a RAID 1 volume on two identical drives. (Note that this is not the same as RAID 10, as we here have two separate RAID volumes, while RAID 10 is one (1) RAID volume).
    At least two drives are required. Both RAID volumes must use all the drives in the array, e.g. a 3-drive RAID 0 and a 3-drive RAID 5.

    How do I set up BIOS and install Windows XP / Windows Vista / Windows 7 on let's say a RAID 0 Volume?
    That's a good question. Windows has sometimes shown problems to install correctly when there is more than one possible target for the OS, for example when more than one RAID Volume / single Hard Drive are connected to the ICH8R / ICH9R / ICH10R (H67 / P67 storage controller.

    The fault proof way is to disconnect all HDDs from the ICH8R / ICH9R / ICH10R / H67 /P67 controller, except those that hold the RAID volume, or the single Hard Drive, on which you want to install Windows.

    In the following example we are going to install Windows on a RAID 0 volume to get maximal performance using two disk drives which we connect to, for example, SATA1 and SATA2.

    Set 'Configure SATA as' ('SATA Configuration') to [RAID].
    Save and Exit (<F10>).
    Intel recommends the RAID configuration for AHCI / RAID to get maximum future flexibility, even if no RAID is planned for now. This will result in a "RAID Ready" system, which later on can be migrated to a RAID volume of your choice, without the need to re-install the OS. The RAID driver also includes the AHCI driver.

    Creation of the RAID volume (skip this part when you install OS on a single drive).
    When BIOS is starting up again, press <Ctrl-i> to enter Intel Rapid Storage Technology option ROM. (Note: The 'option ROM' will not appear if only one HDD is connected to the ICH8R / ICH9R / ICH10R / H67 /P67 controller, or if 'Configure SATA as' ('SATA Configuration') is not set to [RAID]).
    Select: Create RAID Volume.Give the RAID volume a name, for example SystemRaid0.
    Follow the instructions and create only the RAID 0 volume for Windows, and when ready
    Exit the 'option ROM'.

    Exit from BIOS (press <F10>).
    When BIOS is starting up again, press <Del> to enter BIOS Setup and set up your Boot Priority - DVD as first boot device and the RAID volume you just created as the second boot device.
    Insert the Windows Installation CD/DVD.
    Save and Exit (<F10>).
    When BIOS has restarted, Windows Setup begins.

    Note: Unless you have one of the three USB Floppy Drives listed here, WinXP demands an internal Floppy Drive for the F6 installation. An USB Flash Disk will not work, nor will a CD/DVD.
    If your PC doesn't have an internal Floppy Drive, I recommend using the excellent, and free, utility nLite, to create a new installation CD, based upon the one you already have, with integrated (slipstreamed) Intel(R) RST Driver Files for F6, and at the same time, include the latest Service Pack (SP3). The utility is easy to use. You will now have a Windows XP Installation CD that doesn't need the F6 installation method - just a normal installation.

    In the very beginning of the Windows XP Setup, you will be asked for Third Party Drivers.
    Press <F6>.
    Setup continues, and later on you will be asked to provide the drivers.
    Insert the floppy containing the 32-bit/64-bit Intel(R) RST Driver Files for F6, (or later) at Intel's website.
    Press <S> and select the "Intel(R) Desktop/Workstation/Server Express Chipset SATA RAID Controller", which also includes the AHCI driver.

    Windows Vista and Windows 7:
    Note: Although Vista/Win7 will install on a RAID array without loading the Intel drivers, I strongly advice to get the latest drivers from Intel's website.

    When the Windows install asks 'Where do you want to install Windows', select the RAID volume / single Hard Drive where you want to install Windows Vista.
    Insert the floppy containing that the 32-bit/64-bit Intel(R) RST Driver Files for F6, (or later) at Intel's website.
    If you don't have a Floppy Drive in your PC, then copy all (7 or 8) files to an USB Flash Disk. (Vista/Win7 handles Floppy Drive, USB Flash Disk and CD-ROM).
    Down to the left, click 'Load Driver'.
    Select the driver "Intel(R) Desktop/Workstation/Server Express Chipset SATA RAID Controller", which also includes the AHCI driver.

    Alternatively, use the integrated RAID/ACHI drivers for the installation.

    Windows XP, Vista and Windows 7:
    When Windows is fully installed (including latest Service Pack + patches), install this before anything else:

    Intel INF Update Utility

    Then install:
    Intel Rapid Storage Technology (or later) (full version with the utility Intel Rapid Storage Technology + RAID/AHCI drivers).

    Now connect any other Hard Drive(s). If you want to create another RAID volume, use the utility 'Rapid Storage Technolgy' for that.
    (Press Start - All Programs - Intel - Intel(R) Rapid Storage Technology).

    Press Start - right click My Computer - Manage - Disk Management.
    New RAID Volumes and single HDDs will here be seen as Unallocated.
    Initialize - (Partition) - Format.

    Available drivers to choose from in "F6" / "Load Driver" installation:
    AHCI drivers:"Intel(R) ICH7R/DH SATA AHCI Controller"
    "Intel(R) ICH7M/MDH SATA AHCI Controller"
    "Intel(R) ICH9R/DO/DH SATA AHCI Controller"
    "Intel(R) ICH9M-E/M SATA AHCI Controller"
    "Intel(R) ICH10D/DO SATA AHCI Controller"
    "Intel(R) ICH10R SATA AHCI Controller"
    "Intel(R) 5 Series 4 Port SATA AHCI Controller"
    "Intel(R) 5 Series 6 Port SATA AHCI Controller"
    "Intel(R) 5 Series/3400 Series SATA AHCI Controller"
    "Intel(R) Desktop/Workstation/Server Express Chipset SATA AHCI Controller"
    "Intel(R) Mobile Express Chipset SATA AHCI Controller"

    RAID drivers:"Intel(R) ICH7R/DH SATA RAID Controller"

    "Intel(R) Desktop/Workstation/Server Express Chipset SATA RAID Controller""Intel(R) Mobile Express Chipset SATA RAID Controller"

  5. thanks sa reply very helpful, what if pag ang hard drive is IDE hindi SATA, paano ito gawin.

    thanks again bongky

    Same lang gagawin sir.. Basta may feature na Raid yung board hehe
    Pag IDE kailangan naka Enable yung Marvel or JMicron

    Teka, yung requirement mo is to aggregate the storage space of 8 x 20GB drives, diba? You can also consider JBOD. But just the same, I think it would be better for you to just purchase a large capacity drive than to do IDE PATA magic with several smaller drives.

    You'd need a separate RAID card to connect more than 4 IDE PATA devices to a typical older PC (assuming the mobo has only 2 IDE PATA ports). In addition, you'll need to configure all the IDE controllers to cooperate nicely with each other.

  8. thanks josekym
