Formatted pool capacity

The formatted pool capacity is the capacity of initialized free space and the reserved capacity of a pool, but not the capacity of all the free space and reserved capacity of the pool. The free space of the pool is monitored by a storage system. Space is formatted automatically if needed. You can confirm the formatted pool capacity in the View Pool Management Status window (see View Pool Management Status window). Depending on the load of the storage system, the format speed of the free space and reserved capacity of the pool is adjusted. For the pool of pool-VOLs that have accelerated compression enabled, the formatted pool capacity is the pool capacity, not the parity group capacity.

New pages are allocated, then initialized, during data write operations to the V-VOL. If a significant number of new pages are allocated, initialization might be delayed as a result of conflicts between data write and new page initialization processes. Such conflicts could occur, for example, when you create a file system of new DP-VOLs from the host. You can initialize the free space of a pool in advance to prevent delays in data write operations.

To change the method of performing the function to format the free space of a pool, contact the customer support.
