Cache capacity with capacity saving-enabled V-VOLs

I/O operations for capacity saving requires access to cached metadata. Metadata cache uses the same CLPR as the cache of user data.

For VSP F350, VSP F370, VSP F700, VSP F900, VSP G350, VSP G370, VSP G700, VSP G900, we recommend installing at least the following capacity (whichever is larger):

• Recommended capacity calculated using the capacity in Cache capacity with Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe or Cache capacity without Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, active flash for mainframe, Cache Residency Manager, and Compatible XRC.
• <total capacity of capacity saving-enabled V-VOLs> x 0.2%

The following table lists recommended cache capacity when all volumes in a storage system are capacity saving-enabled V-VOLs.
