Use the following formula to calculate the number of cache management devices that a DP-VOL requires. In this formula, the user-specified capacity is the user area capacity of a V-VOL.
ceil(user-specified-capacity รท max-capacity-of-cache-management-device)
ceil: round up the calculated value to the nearest whole number.
For a DP-VOL with the deduplication or compression function enabled, use twice the number of the cache management devices calculated by this formula.
For each deduplication system data volume, 14 cache management devices are used.
