Combine Disk Spanning with Raid 1/0? Even 5?

[Philippine Mango]

Lets say you have 10 1GB HDDs, and 3 10GB HDDs, can you volume span the 10 1GB drives into a 10GB volume, then Raid 5 that volume with your other 3 10GB HDDs? When you lose a drive in a spanned volume, lets say you take it out and bootup the array, what happens to the volume? Does the data get moved around in any way? Or does the volume simply change size? Can you combine Spanned drives with a Raid configuration with the Windows 2000 drive management utility?

Spanning is JBOD.

If your volume "spills over" into the now defunct disk you wind up with a full drive that's unusuable.

LSI hosts use SPAN to define RAID10 and 50 too and that's a different animal.

Ok, so can you combine JBOD and Raid 1/0/5?

 

[Minerva]

It really depends on your host.

The cheapies on mainboards probably don't. High end "enterprise" stuff can be configured all kinds of ways.

What about software raid in windows? Any OSs support this feature?
