IBM introduced zEDC compression (and encryption) for zFS in z/OS 2.3. When you get upgraded to at least z/OS 2.3, including for all shared zFSes across a Sysplex, your new zFS file systems can default to compression at format time, still with the possibility to override the default. Here's the z/OS 2.4 documentation explaining how to do that via the IOEFSPRM configuration option: https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.ioea700/compress_always.htm If you can default to encrypted as well (format_encryption=on), even better. - - - - - - - - - - Timothy Sipples I.T.
