Performance
Response time broken down into connect, disconnect, pending and IOSQ; cache efficiency; contention in the arrays and on the channels.
Expertise
Thirty years of z/OS storage expertise, behind the tool
zPulse automates the analysis. Our engineers have spent thirty years reading z/OS storage data. Use the tool on its own, or have an expert read the results with you.

Why an expert
A graph tells you something is slow. Experience tells you why.
zPulse reads RMF and CMF reports, DCOLLECT extracts and tape catalogues, and turns them into response-time breakdowns, cache and queuing indicators, capacity trends and tape activity, far faster than by hand.
The tool does the counting. The expert does the reading: which of these ten curves matters on your site, what changed after last month's migration, which setting to touch first and which to leave alone.
That combination is what we sell: the software, and the people who built it and use it on real z/OS estates.
Trust… but verify. Every number in a report should lead you back to the data it came from.
Audit
What a one-off audit covers
Scope is agreed with you beforehand. The usual subjects are these four.
Capacity
Growth by storage group and by array, remaining headroom, and when you will run short.
DASD and tape tuning
Volume balancing and alias settings, tape mount delays, drive and virtual tape cache usage.
Disk array migration
Profile your workload before the move, size the target array, and compare before and after.
Included in the licence
Support and training come with zPulse
You do not buy them separately. They are part of the licence.
Support
Help from Technical Storage engineers, who know both zPulse and z/OS storage.
Training
Your team learns to read the results and to act on them.
Use case
An insurance group finds the real source of its slow batch window
- Context
- The nightly batch window was overrunning on some mornings. Monitoring showed nothing unusual on the volumes involved.
- What the study showed
- Pending time on a group of volumes came from contention in one array's back end, caused by a data copy job scheduled at the same hour.
- What changed
- The copy job moved to another window. Response time on those volumes fell by about a third, and the batch window stopped overrunning.
