Use SFW to create a separate cluster disk group for the quorum disks. Microsoft recommends 500 MB for the quorum disk.
If you add other volumes to this disk group, any failures related to their operation can cause disruptive failovers of the quorum volume. If a volume in the group experiences a high level of read/write activity, failovers may result from delayed access to the quorum volume by Microsoft clustering.
Veritas recommends the following configuration for the quorum disk group to create the mirrored quorum volume:
For a failover cluster, use three small disks; you need a minimum of two disks.
For a campus cluster, use four small disks.
Use the following guidelines when creating the mirrored volumes:

For a high-availability failover cluster, specify the three mirrors.
For a campus cluster, specify the four mirrors.
Detailed procedures are available for creating cluster disk groups and volumes.
