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

Chapter 2: Configuration Information 4
Supported HBA Drivers
The Host Bus Adapter vendors frequently release HBA drivers for Linux.
HP has chosen to narrow the number of versions that it will validate with
Clustered File System. Other drivers will work, but may not produce
optimal results during failure or failover situations.
HP will continue to evaluate newer drivers with Clustered File System as
they become available from the vendors. Check the QuickSpecs on the HP
web site for the supported HBA driver versions before upgrading to a
newer driver from your HBA vendor.
NOTE: QLogic and Emulex cards should not be placed in the same fabric
zone unless both HBA manufacturers have approved this
configuration.
Server 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.
The minimum requirements for cluster servers are as follows (see the HP
Clustered File System QuickSpecs on the HP web site for more specifics):
• A supported HP ProLiant server architecture (only HP ProLiant
servers are supported):
– 32-bit Intel- or AMD-based servers (single processor or
multiprocessor) running a supported operating system and kernel.
– AMD Opteron or Intel EM64T servers running a supported 32-bit
or 64-bit operating system and kernel.
• A supported operating system and kernel.
• 512 MB of memory per processor minimum (2GB per processor is a
better starting point).
• 40 MB of disk space on /opt for the Clustered File System software.
• 80 MB of disk space on /opt for the Management Console and mx
utility.
