2.2. TCP/IP Network
All GFS nodes must be connected to a TCP/IP network. Network communication is critical to the
operation of the GFS cluster, specifically to the clustering and locking subsystems. For optimal per-
formance and security, it is recommended that a private, dedicated, switched network be used for GFS.
GFS subsystems do not use dual-network interfaces for failover purposes.
2.3. Fibre Channel Storage Network
Table 2-2 shows requirements for GFS nodes that are to be connected to a Fibre Channel SAN.
