The zHyperLink Express feature was announced by IBM in September 2017, providing up to 10x better response times in read cache hits. The roll out to production has been slower than most new interface technologies on the mainframe given that it’s an adjunct and not a replacement to FICON.
Watch Joe Hyde as he shares some recent Db2 production data which highlights the speed of zHyperLink read I/Os. Joe will also cover the following topics:
- A brief overview of the zHyperLink technology
- Performance Statistics at various levels of data capture and why you’d want to look at them
- zHyperLink PCIe Adapter (RMF 74.9)
- Volume (RMF 74.1)
- Data set (SMF 42.6)
- DSS Sync I/O link (RMF 74.8)
- Production DB2 Financial Sector Results
- Production DB2 Data Warehouse Results
- Lessons learned
Being familiar with the zHyperLink statistics will help you track and verify the performance benefits of this technology. It also helps justify the investment needed to incorporate the zHyperLink technology in your I/T environments.
The lessons learned from this recording should answer your questions and help you fully exploit this new technology.
