2.3. Fibre Channel Storage Network

Table 2-2 shows requirements for GFS nodes that are to be connected to a Fibre Channel SAN.

RequirementDescription
HBA (Host Bus Adapter)One HBA minimum per GFS node
Connection method

Fibre Channel switch
Note: If an FC switch is used for I/O fencing nodes, you may want to consider using Brocade, McData, or Vixel FC switches, for which GFS fencing agents exist.
Note: When a small number of nodes is used, it may be possible to connect the nodes directly to ports on the storage device.
Note: FC drivers may not work reliably with FC hubs.
