| Quote: | For a cluster utilizizing a SAN for shared storage, what is the optimum
storage configuration for the quorum and log drive resources?
Option A : Setup each shared logical drive (LUN) on it's own set of RAID 1
physical disks
|
This is what I would recommend. I carve out a small LUN of 1 GIG for the
Quorum and 1 GIG for MSDTC.

with LUNs defined for each necessary storage resource.
|
Overkill for the Quorum.

contention on the shared physical resources?
