When to run zOS DEFRAG?

Below is NOT a map of the Far East. It is the fragmentation map of disks in a zOS data-center. The red indicates the “Average Frag Index” is too high, which induces slower I/O response times and poor disk space occupancy. EADM 2019 lets you see in seconds the fragmentation status of volumes in all LPARs.

DEFRAG can be a big drag for data-center productivity. Thanks to a new partnership with INTERCHIP AG, Technical Storage now offers a simple and automated solution to guarantee low fragmentation of your zOS volumes round-the-clock without stalling any other processes.
