It’s a well known phenomenon, senior mainframe engineers are now enjoying a well deserved retirement.
New z/OS DASD performance features keep arriving to speed up IOPS and reduce CPU consumption. Yet these technologies are seldom clearly understood by IBM System Z customers. Response times are now given in microseconds. One thing is certain, daily changes in configurations have an effect on performance and when there is I/O response time, someone is waiting.
What solutions are there to help datacenters maintain and improve inhouse mainframe skills?
This summer, EADM developers took up the heights for tandem skydiving. Accompanied by a pro, they jumped from an altitude of 3.5 km. Do like them: leap into z/OS disk performance management. In tandem with EADM, the sky is the limit.
