Capacity saving and accelerated compression functions

The VSP G series and VSP F series storage systems provide the following functions to make efficient use of user capacity:

• Capacity saving: The capacity saving function includes data deduplication and data compression. Capacity saving enables you to reduce your bitcost for the stored data by deduplicating and compressing the data. Data deduplication and compression are performed by the controllers of the storage system.

• Accelerated compression: The accelerated compression function enables you to reduce your bitcost for the stored data by allowing you to take advantage of the compression function in the FMC drives. Accelerated compression allows you to assign FMC capacity to a pool that is larger than the physical capacity of the FMC parity groups. The data access performance of the storage system is maintained when the accelerated compression function is used, as the compression engine is offloaded to the FMC drives.
