HP XP P9500 Storage - Manual (Page 34)

With Fibre Channel connections, you can use the switches as ordinary switch connections. No
special settings are required for the HP XP P9500.
Direct connections up to 10 km with single-mode longwave Fibre Channel interface cables are
supported. Link speed determines the maximum distance you can transfer data and still achieve
good performance. The following table shows maximum distances at which performance is
maintained per link speed, over single-mode longwave Fibre Channel.
Distance maximum performance maintained Link speed
10 km 1 Gbps
6 km 2 Gbps
3 km 4 Gbps
3 km 8 Gbps
