RAID 5??

[lou]

I have a server that was originally setup with three 33GB
drives. RAID0. We decided to rebuild the drives. The
first drive was split in half to make the C: 16.5 GB.
Then the rest of the drives were all spanned together in
windows. What is this drive configuration called? RAID 5?

Hello Lou,

It's called a spanned volume. A RAID5 set would be fault tolerent. This
page talks about the different RAID types and how they work...

Sounds like a spanned volume to me. Take a look in Disk Management Help
for more precise terminology.

RAID is for redundancy. If you're using all 3 hard
drives, totalling 99 GIGS - minus the 16.5GB for c:, then
you likely don't have any form of RAID anymore since it
sounds like you have a 16.5GB and a 82.5GB drive.

RAID 5 is a good way to have redundancy of your data since
it is data is written across striped disks. Parity
information for your data is also written to a disk but
not to the same disk that contains the data, so you can
easily restore information from one disk if it would fail.
If more then one disk would fail at the same time however,
you will not be able to restore the information from the
disks - in that case you will have to use your backup
tapes. RAID 5 requires a minimum of 3 hard drives and your
hard drive to support RAID 5 or you will have to upgrade
your disks from basic to dynamic

You can read about striped volumes with parity (RAID 5)
and without (RAID 0) in those two knowledge base articles:
