FICON References
The FICON channel delivers a 1 or 2 Gbps link data rate to servers, switches,
control units and storage devices. The link speed is auto-negotiated, point-to-point,
between server and device and is transparent to users and applications. FICON
channels offer fast, efficient data transfer while allowing reuse of currently installed
single mode and multimode fiber optic cables. FICON channels can coexist with
ESCON channels on all zSeries 800 server models.
The table below lists the FICON channel cards. Both FC 2319 and FC 2320 support
3 three modes of operation:
v FC - native FICON
v FCV - Fibre Channel Converter - used with the 9032 Model 5 Director with bridge
card
Note: The FICON Express LX feature is limited to 1Gpbs.
v FCP - Fibre Channel Protocol - attachment to SCSI disks in Linux environments.
