There are four ports for each interface board or a total of 32 host interfaces for a fully
configured system. An ESCON interface board is shown in Figure 14. A FICON interface
board has a similar appearance. The FICON interface card is available with 1Gbit/sec or
2Gbit/sec transfer rates.
A Lightning 9900 V Series system can connect to both mainframe and open system
hosts, thereby consolidating the storage for an enterprise under one roof for consistent
performance, availability, and ease of management. This is shown in Figure 15.
