You are designing a new HPE 3PAR StoreServ all-flash array for the customer.

In an all-flash array like the HPE 3PAR StoreServ, the compaction ratio typically offers the highest efficiency. Compaction includes both deduplication and compression, which reduces the amount of physical storage needed by eliminating redundant data and compressing the data that is stored. The compaction ratio directly impacts storage efficiency, allowing for more effective utilization of the available flash storage, thereby reducing the total cost of ownership and improving performance.
