Title: OD77 vs OD77HW
Post by: cmodpuser on March 14, 2019, 07:54:38 AM

We have all apps defined with OD77 compression for CMOd of z/OS. Can OD77 HW be used for z13? What are the hardware requirements for OD77HW? Would that offer performance benefits.
We do not have zEDC cards.

Hello cmodpuser ---

You need to review this:

http://www.odusergroup.org/forums/index.php?topic=1942 (http://www.odusergroup.org/forums/index.php?topic=1942)

It has all of the commands to issue to see if you're set up for hardware compression.

I found these charts interesting reading on zEDC  (zSeries Enterprise Data Compression):
