System Requirements

This chapter describes the system requirements for Red Hat GFS 6.0 and consists of the following
sections:
Section 2.1 Platform Requirements
•
Section 2.2 TCP/IP Network
•
Section 2.3 Fibre Channel Storage Network
•
Section 2.4 Fibre Channel Storage Devices
•
Section 2.5 Network Power Switches
•
Section 2.6 Console Access
•
Section 2.7 I/O Fencing
•

2.1. Platform Requirements

Table 2-1 shows the platform requirements for GFS.
Operating System
Red Hat Enterprise Linux AS, ES, or
WS, Version 3 Update 2 or later
Table 2-1. Platform Requirements

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.
