HPE XP7 Mainframe Suite Performance

HPE XP7 Mainframe Performance Suite consist of Compatible PAV, Compatible Hyper PAV and High Performance FICON software. Compatible PAV Enables high performance concurrent access of mainframe volumes by permitting a mainframe host system to issue multiple I/O requests in parallel to individual logical devices within the XP7 Storage. Compatible PAV also enables the use of the multiple allegiance feature in z/OS when using multiple physical mainframes to access the same volumes in a single array. Compatible PAV provides static or dynamic PAV functionality Compatible Hyper PAV greatly reduces the number of PAV aliases needed per logical subsystem while maintaining response times. PAV aliases are only bound to PAV bases for the duration of a single I/O operation, thus reducing the number of aliases needed.

High Performance FICON for system z or zHPEF is an enhancement of the FICON channel architecture; which also means compatibility with certain standards such as Fiber Channel Physical and Signaling standard (FC-FS), Fiber Channel Switch Fabric and Switch Control Requirements (FC-SW), and Fiber Channel Single-Byte-4 (FC-SB-4) standards. Enhancements have been made to the z/Architecture and the FICON interface architecture to deliver improvements for online transaction processing (OLTP) workloads. zHPEF is implemented exclusively in System z10. When High Performance FICON is exploited by the FICON channel, the z/OS operating system, and the control unit; the FICON channel overhead will be reduced. This is achieved by simplification of the protocol, and by reducing the number of information units processed, resulting in more efficient use of the fiber link.
