Quorum disk or partition?

[Richard Liddiment]

Is the Quorum Disk a physical disk or a partition? Please tell me it's just
a partition on the shared storage area. If not, I'm very confused!

Microsoft seem to be suggesting three physical drives:
a.. Disk 0 (usually drive C)
b.. Disk 1 (quorum)
c.. Disk 2 (data drive)
But this would be crazy! The recommended size of the quorum is only 500Mb
but the smallest SCSI's are around 18GB! I would need two, so it's at least
mirrored, and that would take up two valuable slots of my shared storage
space!

I'm looking at starting with three 36GB SCSI using RAID 5 as the shared
storage and anticipated setting up a 500Mb partition on that for the
quorum - would that be sensible?

It is highly recommended that you separate the quorum disk as much as
possible from the rest of your cluster's storage resources. The quorum disk
has a tendency to corrupt, so you want to keep important data away. If your
storage array cannot carve out a 500mb slice, then partitioning is a good
idea.
