Does Windows 2000 Server support BOTH mirroring (for the system partition)

and RAID 5 for the rest of the available space on 3 drives?

Thanks,

Since this is software ie. partition mirroring, yes you can have two of the drives with mirrored partitions and three drives with a raid5 partition.  This would leave the space on one drive that is not available on the other two due to the mirror set.



Personally I would never recommend or use software raid in production environment.  Raid cards are cheap these days and so much faster/better then software raid.  Hardware raid takes the load off the cpu thereby making your system faster/more responsive.  Hardware raid also has the ability of doing hot spares so if a drive fails in your raid array the hot spare kicks in and replaces the failed drive without you ever touching the system.

I doubt it - RAID5 itself requires three drives. Corrections welcome, of

course.



NB: I don't recommend software RAID on servers. Hardware SCSI RAID with good

fast drives & a hotspare is well worth the extra expense.

Yes, it does. Create your system partition on disk 0, mirror it to disk 1,

create your data partition on disks 0, 1 and 2. You will get free space as

large as your system partition on disk 2.

Thanks - I thought so -

I wish this was on a HW RAID, but the site is a remote one, and rebuilding

is not a feasable option, so this should be the next best thing. I already

have the mirror established, so the addition of the the RAID 5 for the

remainder gives a bit more of a safety net.

They even had hot-swappable IDE RAID cards available. I setup a Promise

SX6000 RAID controller with 6 x 250GB IDE drives and even tested the

hot-swap, dang drives are getting more like SCSI every day.
