Pipelining
Protocol interlock is reduced.
CCW handling
Multiple I/Os execute concurrently per one channelNumber of concurrent I/Os
16,384 devices per channelAddressing
Full-duplexData transfer
Connectivity improvements in FICON/zHPF:
• The interlock between the host and RAID is lowered in terms of the protocol.
• Throughput is increased using multiple I/O process and bi-directional data transfer.
• Increases in the number of the connectable devices per channel.
