Cabling Your Cluster Hardware
When attaching multiple storage systems with your cluster, the following
rules apply:
•
There is a maximum of four storage systems per cluster.
•
The shared storage systems and firmware must be identical. Using
dissimilar storage systems and firmware for your shared storage is not
supported.
•
MSCS is limited to 22 drive letters. Because drive letters A through D are
reserved for local disks, a maximum of 22 drive letters (E to Z) can be used
for your storage system disks.
•
Windows Server 2003 and Windows Server 2008 support mount points,
allowing greater than 22 drives per cluster. For more information, see
