zHPF demystified
The System z High Performance Ficon feature is now standard on Ficon Express-2 -4 and -8 Channels. What is this feature? How does it improve channel performance? This session will describe how the Channel and Control Unit negotiate support for zHPF, the difference between Ficon and zHPF in how commands and data are transported to get significantly higher performance, and the RAS enhancements that zHPF provides.
