Table 2-2 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 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.
