Hi David, I think you may be referring to the three z/OS V2.1 zfs cache default changes??? Basically, they are dependent on the amount of real memory on the LPAR available at IPL. The default will vary between systems. You may want to check out the helpful migration Health Check ZOSMIGV2R1_ZFS_VERIFY_CACHESIZE to tell you what you are using today, and what the new default will be once you are at z/OS V2.1.
