The data compression function enables you to convert the stored data into data with smaller data size by encoding without reducing the amount of data information. Software compression is performed on the controller. Hardware compression is performed on the accelerator dedicated to data compression. See Compression accelerator for details. The LZ4 compression algorithm is used for data compression using software with the DKCMAIN firmware.
The compression accelerator feature requires a higher performance compression algorithm than the algorithm used for data compression with software.
The data compression function can be enabled for each DP-VOL used for Dynamic Provisioning.
