98 Configuration and Tuning GPFS for Digital Media Environments
zoning configuration of one switch (itsosan1). As all nodes have two HBAs, the
zoning of the second switch is similar, using the second HBA and the second
controller (B) of the DS4500 instead. Aliases are used for configuration, as
names are easier to remember than numbers.
Example 3-5 FC-switch (2109-F32) itsosani1 profile - partly (zone configuration only)

3.2.4 Servers
IBM offers a wide range of servers suitable for running GPFS. The latest
supported server hardware list can be found at:
http://www.ibm.com/servers/eserver/clusters/software/gpfs.html
Whenever you chose server, make sure it fits your performance and connectivity
needs, and also check for latest microcode updates available. Make sure to use
the correct files for your platform. Follow the instructions described in the
README file.
In our environment we have used several platforms, but we have closed as an
example two IBM Eserver® pSeries 550 with the following configuration:
4 processors
8 GB RAM
8 x 73 GB internal SCSI disks divided in two SCSI buses
