Chapter 7 Fibre Channel

Controller Configuration

The RamSan allows the user to select the topology, link speed, and failover options for the Fibre Channel Controllers. RamSan supports Point- to-Point and Arbitrated loop topologies and can auto-detect the topology. It supports 1- and 2-Gbit link speeds and can auto-detect the speed. When more than one Fibre Channel Controller is installed, the controllers can be set to back each other up. The following two sections provide additional details.

7.1Changing Fibre Channel topology and link speed
