Connectivity
A robust I/O subsystem provides ultra high-speed communications within a z800 server, between servers, to devices and out to users. As a result, greater integration between traditional and Web applications is available for maximum e-business effectiveness.

Connectivity to I/O devices with z800 servers is available through ESCON® and the FICON™ Express features.

Up to 240 ESCON channels are available on z800 servers. The 16-port ESCON card is used with 15 ports available and one reserved as a spare. ESCON channels are offered in four-port increments distributing channels across features for high availability.

Up to 32 FICON Express channels are available on the z800. Each FICON Express™ card has two ports. FICON Express, with its high-speed PCI bus, has bandwidth potential of 100MB/sec. and provides high performance for large data transfers and remote vaulting applications.

Linux users can take advantage of new FCP function on z800 servers which supports connectivity to industry-standard SCSI devices. This support is enabled on the FICON Express card running in FCP mode. Native FICON and FCP devices are designed to provide outstanding performance, great configuration flexibility, and low total cost through channel consolidations. The family of OSA-Express features (Gigabit Ethernet, Fast Ethernet, ATM, and Token-Ring) available on z800 servers are all capable of achieving line speed. Explosive Internet growth has contributed to a shortage of Internet Protocol (IP) addresses. IPV6, new on z800, expands the IP addressing scheme from 32-bits to 128-bits, enabling global addressability.

The z800 servers support one I/O cage with 16 card slots. A minimum of four ESCON channels or two FICON Express channels are required on all models except the z800 Model 0CF Coupling Facility.
