K7V Dragon+ Promise RAID chip HELP

    I have an existing RAID0 array with a drive on each Promise channel. I
    bought new drives an would like to create a 2nd array. I've read in the
    manual that you can have two RAID0 arrays at once. My question is, can I
    just throw the new drives on each channel and have my existing RAID be okay?
    Any special steps I need to pursue to keep the original RAID intact and
    create the new? Jumper settings?

    Thanks much,

    Yes, that shouldn't be a problem. But I would be sure to backup the
    system first. You never know when something may go wrong when doing
    something like that.

    But with four nice drives you have some other choices that
    might give you equal speed PLUS safer data.

    Consider the possibility of NOT creating a 2nd array, but rather
    leaving the BOOT drive simple. Makes it easier to recover or
    migrate to a new hard motherboard/controller combo if necessary.
    If it's a simple, single, drive that can be done without any
    special drivers or rigamarole. The OS itself really doesn't
    benefit that much from RAID 0, because stuff tends to get
    into memory and stay there. You could gain by putting
    your paging files on the RAID 0 array, so if code segments
    did get sent out, they'd come and go quickly.

    Use that second drive to make Ghost images of the first one
    every time you make a major change, and you'll have a real
    nice disaster recovery scheme. Also use it for doing
    incremental backups of the RAID 0 array, which is rather
    vulnerable to failure of either of its two hard drives.

    Then use the RAID array for anything you want to have RAIDed
    for speed. For example, install games over there. And multi-media
    files. You know what I mean. Just bear in mind it's twice as
    likely to get lost from a hard drive failure. If it's your
    financial records, put it over on that single drive.

    You also could go RAID 0+1 (if your controller supports it),
    but you'd lose a lot of useful space.

    In sum, you can now on a single system trade off speed for
    reliability, AND have some room to do fast, live, backups
    to keep everything as safe as possible.

    I've a friend who had a nice 4-drive RAID 0+1 setup. Until the
    controller died and took one drive from each set with it. oops.

    Dragon+ doesn't support RAID 0+1. Only 0 or only 1.
