Calculating cache capacity

Before you partition cache memory into one or more CLPRs, calculate the cache capacity that you need for the storage system. If necessary, install additional cache memory.

The recommended cache capacity is different for different system configurations. System differences include:

• Number of mounted MP units

• RAID level

• Number of installed drives

• Use of the following specialized applications: Dynamic Provisioning, Dynamic Tiering, active flash, or Universal Volume Manager
