HP StorageWorks Clustered File System 3.1.1 for Linux Installation Guide (May 2006)

Chapter 2: Configuration Information 5
• 30 MB of disk space on /var for log and runtime files.
• Ethernet 10/100/1000 port.
All servers in the cluster must be on the same subnet.
Management Console Requirements
Servers running the Management Console must have a windowing
environment installed. The Management Console requires that the
display be set to a minimum of 256 colors.
NTP Requirements
NOTE: To ensure that file times are consistent across the cluster, it is
important that all cluster servers operate with synchronized time-
of-day clocks. An NTP server is one commonly used mechanism
for synchronizing system clocks.
Network Configuration Requirements
Networks used with Clustered File System should be configured as
follows:
• Each network interface card (NIC) must be on a separate physical
network. For example, you could use either a separate Ethernet switch
for each network or a managed switch that allows network traffic to
be isolated.
• Each NIC must be on a separate logical IP network.
• The network topology is typically symmetrical; that is, each server in
the cluster should be connected to the same set of networks.
• One of the NICs is typically used for a private intra-cluster subnet.
This is required for optimal performance.
• The following flags must be set on each network interface: Broadcast,
Multicast, Up, Running.
• Contact your HP storage specialist for information on additional
recommended NIC settings for optimal performance.
