Comments
This APAR provides guest support for High Performance FICON for System z (zHPF). zHPF is a performance and reliability, availability, and serviceability (RAS) enhancement of the z/Architecture and the FICON channel architecture implemented in the zEnterprise 196, zEnterprise 114, and System z10 servers and the System Storage DS8000 series. Exploitation of zHPF by the FICON channel, the operating system, and the control unit is designed to help reduce the FICON channel overhead. When both the FICON channel and the control unit indicate support for zHPF, transport mode I/O is supported in addition to command mode I/O. Use of zHPF requires the function to be installed on the machine (processor complex and channels) and the storage controller, and requires support in z/VM and the exploiting guest. The z/VM 6.2.0 publications at the z/VM web site http://www.vm.ibm.com/library/ contain the publication changes for this support.
