    Users of IBM's HSM that have the ZCOMPRESS option enabled for TAPEBACKUP, TAPEMIGRATE or ALL can save CPU cycles without increasing the run-time of their HSM jobs or increasing their CACHE usage. If you enable the new Tape Compression/Encryption feature of CA 1 Flexible Storage, you can specify that you want to enable Compression services only (no encryption). While you will still get the same z/EDC compression as ZCOMPRESS will give you, CA 1 Flexible Storage has the option of offloading the compression (and encryption if performed) services to any zIIP engines you might have. Using zIIP engines instead of your general CPU will save on reported MIPS usage.
