2.4. Fibre Channel Storage Network

Table 2.2, “Fibre Channel Network Requirements” shows requirements for GFS nodes that are to be connected to a Fibre Channel SAN.

Requirement Description
HBA (Host Bus Adapter) One HBA minimum per GFS node
Connection method
Fibre Channel switch
Note: If an FC switch is used for fencing, you may want to consider using Brocade, McData, or Vixel FC switches, for which Red Hat Cluster Suite fencing agents exist. Refer to Configuring and Managing a Red Hat Cluster for more information about supported fencing agents.
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.
