Windows XP Raid striping / Dimension 8300 motherboard support

Discussion in 'Dell' started by Thomas G. Marshall, Feb 3, 2006.

  1. [DIm 8300 / 3.0 Ghz / 800 Mhz FSB / Windows XP Pro / yada]

    Questions about striping on my dell.

    1. What is the theoretical data throughput of the EIDE on the 8300?

    2. Does the striping/spanning ability of XP Pro live entirely within the OS
    or is there raid hardware support (a raid controller) on the motherboards of
    the 8300. *IF THE LATTER* then is it better to use the hardware support and
    keep the OS in the dark?

    Just getting started in raiding.

    Neither. The 8300 doesn't have RAID built in and neither does XP.
    The 8300 supports ATA100.
    Here's a place to start finding out about RAID.

    According to the help section within XP pro, and the forums in, XP pro most certainly *DOES* have raid support. The
    diskpart.exe utility shows commands for creating the dynamic
    partitions/volumes for it.

    But you've answered the question regarding the 8300. Thanks.

    Part of the confusion may lie in the fact that the 8300 uses an Intel 875
    chipset based board. Most of the retail boards with that (premium) chipset
    do indeed have a RAID controller built into the board.

    Okay, maybe not most but certainly many of them do.

    Well, I thought the chances of there being some hardware raid support to be
    minimal, but likely enough to warrant asking about.

    WinXP Pro can certainly provide spanning of drives.

    If hardware RAID is available, it's ***ALWAYS*** better than software RAID.

    TGM -

    It's a fair question. RAID hardware was actually integrated on the next
    model, the 8400 (Promise controller, I think........)

    Take a look at Device Manager | SCSI and RAID controllers.

    Ok, as I suspected. That the 8400 has all what I *really* wanted in the
    8300 {grumble} is just typical for me LOL. PCI-E and SATA is the first
    thing that ticks me off. {chuckle}

    However, the common usage for "spanning" is that a volume spans multiple
    drives, each drive adding more space. I don't want the space, I want
    throughput speed, hence I'm careful to mention striping.

    Here's the "question" I've been mulling over for a few weeks. Suppose I
    have two drives level-0 *Win XP Software* striped, each EIDE. Does software
    raid grant me 2x-ish speed improvement, like hardware striping would?

    Or does the mere fact that it is software calling the shots greatly clobber
    the throughput? I'm not sure why it would, except that there might be a
    bottleneck I'm not aware of when using software.

    My experience was with a Promise Raid hardware controller. Raid 0
    (striping) gained me no more than 10% in average use, 20-30% in heavy
    sustained use. Not worth double the risk of failure.

    I don't have an 8400, chief. All I got is an 8300 and the controllers look
    like this (with no SCSI/RAID references, as in Win2K.):

    TGM, further, the 8300 *does* have 2 SATA controllers onboard (along with
    dual IDE), just no RAID. But that's why Promise makes SATA RAID PCI cards: HBAs&product_id=107

    So you've got an 8400, and that's the onboard Promise controller ID in
    device mangler?

    No. Yes.

    Glad you think I'm cool. So do my dogs. <g>

    Actually, I may have misled you. If so, it was purely unintentional.

    That was a shot from a Workstation 360.

    I was just showing Thomas(?) what device manager would look like
    with an installed hardware controller.

    Only to those with 8400s, err..., 8300s! <g>

    Seriously... At the time, the PWS was the only model that could
    be configured exactly the way *I* wanted it. Also, it was one of
    the few Dell models that was compatible with a fancy KVM that I
    own. With my office running multiple systems, printers, etc., it
    got mighty hot and noisy. Now that I've placed the PWS in a remote
    area, not only does the office run much cooler, so does the PWS.

    See ya!

    I got a 5150 bustin' my chops right now trying to do a reinstall with RAID1.
    It's pissin' me off .

    Of course I was j/k about the whole PWS snob thing. Truth is, I wish I had
    more opportunity to get my hands on one of those or an XPS model now and

    Having a dog that is a purebred does not qualify it for breeding. Dogs need
    to have several generations of clearances for various illnesses before being
    bred. If you are breeding dogs without taking care as to the genetic
    of the dog (again, being purebred is *not* enough), you are what is known as
    "backyard breeder" and are part of the problem. Most of the congenital
    problems of present day dogs are traceable directly to backyard breeding.
    Spay or neuter your pet responsibly, and don't just think that you're
    the exception and can breed a dog without taking the care described.
