Cabling Your Cluster Hardware 29
When attaching multiple PowerVault MD3200i and MD3220i storage
systems with your cluster, the following rules apply:
• A maximum of four Power Vault
MD3200i and MD3220i
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.
• Windows limits access to drives using limited drive letters which is 22.
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 2008 Enterprise Edition supports mount points, allowing
greater than 22 drives per cluster.
