With EADM AI 2020, Never Sweep z/OS Performance Issues Under The Rug Again

To sweep under the rug is an expression meaning to conceal a problem expediently rather than to remediate it thoroughly. As the mainframe is poised to enjoy many more years of success, the ongoing retirements of top z/OS engineers means storage and I/O performance issues are often swept under the rug.

AI Reduces Risk In City Traffic and In z/OS Mainframe Availability

Beyond the context that individuals are free to circulate, AI algorithms on traffic cameras can locate events or individuals potentially dangerous for the population. Amongst others features, AI video analytics can identify drivers who are texting or are not observing traffic signs and who are at risk of provoking accidents. Such drivers are often repeat offenders.

IT shops are responsible for Performance Management. It’s always been so as each z/OS customer has a specific environment with complex and specific rules. It is the hardware manufacturers’ responsibility to ensure that all z/OS CPU and DASD activity be logged in SMF records each second. IBM’s RMF and BMC’s CMF are reports rich in performance data stemming from SMF datasets.

Technical Storage

Technical Storage's EADM uses your data-rich RMF and/or CMF files. You already have everything you need - there is no need to recreate any data. Our studies can be fully automated and take about 5 minutes to process.  When they are complete, EADM will send you an e-mail with the results.
The software is also invaluable if you are performing system upgrades.  At a time when manufacturers’ are all rolling out new storage solutions, EADM enables our customers to easily verify whether manufacturers' claims about TP Batch response times, storage capacity and other performance rates are accurate.  As we say in the U.S.A., "Trust... but verify!"

Thereafter EADM will save you a lot of time as you follow the I/O performance of your z OS.

Our team has more than 30 years of experience in z OS storage.
