Ultra 711 box

    I have a Sun 711 box marked "UltraSCSI" in the lower left corner on
    the front. Is this box just Ultra1 or will it do Ultra2 or Ultra3
    with LVD drives and an LVD terminator?

  2. Hi,

    It is rated I think for 40MB/s, but why not give it a try at any speed
    you like!

    I don't know how to get Solaris 10 to tell me what speed the SCSI bus
    is running at. I also don't know if the Ultra version of the 711 box
    works in LVD mode or only SE mode.

    The drive box has 6 LVD drives installed and it's connected to the
    external SCSI bus on my Ultra60. I picked up a dual Ultra2 SCSI /
    dual fast ethernet card (501-5727) and a dual Ultra3 SCSI card
    (375-3057) from ebay and want to put the box on one of those

  5. Hi,

    Just put the box on the one you prefer(fastests) and see how it runs!

    Also remember no HD drive will run fasster that 5-70 MB/s, having a
    faster bus connecting them will only make a difference if you have them
    in a raid configuration.

    Just Ultra1 - 20MB/s, no LVD :(

    Note that these boxes, while they accept LVD *drives*, provide a
    single-ended connection to the computer. If you hang them on a LVD
    controller, they will still be operating in single-ended mode.

    *And* the box is self terminating. You don't need (or want) an
    LVD terminator on the end. Though if it is the kind which will
    auto-switch to SE, it will simply confirm what the box is doing anyway.
    The box can even automatically terminate the upper half of the bus if
    you connect a cable to a narrow SCSI box following it -- but that narrow
    SCSI box will probably need a terminator.

    My FEH is too old (yet again) to show either of the cards which
    you got, so I don't know what they are.

    Good Luck,
