Multiple Cluster Configurations for Switches
This section contains instructions for configuring multiple clusters using the same
storage subsystem. This section will refer to steps that can be found in Chapters 3
and 4 of this guide.
Key Considerations
When setting up multiple cluster configurations, be aware of the following key
considerations:
• Maximum configuration in a switch environment
• Virtual disk naming conventions
• Server-to-storage connection paths
Maximum Configuration in a Switch Environment
A switch environment is currently capable of supporting four clusters (two servers
per cluster) and four single storage controllers in four separate storage subsystems (or
four storage controller pairs in four separate storage subsystems). This also enables a
single cluster to have up to four separate storage subsystems or four clusters to share
a single storage subsystem. Considerations are necessary when setting up the first
cluster if the first storage subsystem will be shared by more than one cluster in the
future. Considerations include leaving disks available for additional clusters or
installing expansion cabinets for additional storage.
Virtual Disk Naming Conventions
Table 3-8 shows the naming conventions used with the Large LUN Utility.
