Can you stripe together 2 striped sets?

Apparently RAID 0+1 is more like Raid 5. I always thought 0+1 was a combo of 2 mirrored RAID 0 sets.

Check that link out and check the different RAID configs. I guess I was wrong about some of this stuff.

Edit~~~forget it..I can't read diagrams today apparently...thats what I get for posting and talking on the phone at the same time lol!!:):D

that is what it is isn't it? I swear it is, or at least that is how the highpoint controller on the KD7-RAID says (before smarktards try to bash me for having a KD7-RAID, know that is was a very nice rma from a KR7A-RAID :cool: ).

RAID 0+1 = mirrored stripe sets.

RAID 10 = striped mirror sets.

There is a difference, but IMO it is not too significant because with that many drives different RAID configurations are better.

Yeah it is....lol!! Apparently I'm having troulbe looking at diagrams today! :)

ah now I see, reverse sort of, hehe learn new stuff all the time.

hey ua549, about the # of disks on a ultra3 channel? 15?

15 addressable drives on any wide channel (many SCSI versions including Ultra 3).
7 addressable drives on any narrow channel (mostly ancient SCSI versions).
