368 IBM BladeCenter JS23 and JS43 Implementation Guide
9.1 Supported operating systems
SUSE Linux Enterprise Server 10 Service Pack 1 (SLES 10 SP1) for POWER or
later supports installation on a JS43.
This chapter specifically covers installing SUSE Linux Enterprise Server 11 for
POWER with a DVD and over the network on a PowerVM LPAR.
9.2 Considerations and prerequisites
There are some system configuration considerations and prerequisites prior to
installing SLES 11 on a JS43 partition. They are covered here.
9.2.1 PowerVM LPAR considerations
By the characteristics of the virtualization features in the System p JS43 Blade
Center, the operating system and applications do not know they are running in a
micro-partitioned or virtualized I/O environment. This allows applications to run
unmodified in a partition that takes advantage of virtualization features.
Because the PowerVM partition handles the transition of the virtual adapter’s I/O
operation to the physical adapter, it is important to guarantee that the partition is
properly sized to handle the I/O requirements. A good source for processor and
memory requirements for PowerVM partitions based on I/O requirements is
found at:
http://www14.software.ibm.com/webapp/set2/sas/f/vios/documentation/perf
.html
Additional information about virtualization and LPAR setup is available in
Chapter 4, “System planning and configuration using VIOS with IVM” on
page 71.
9.2.2 SUSE Linux Enterprise Server 11 installation considerations
The SUSE Linux Enterprise Server 11 document recommends at least 512 MB
of RAM to install SUSE Linux Enterprise Server 11.
Tip: We recommend at least 1-2 GB per PowerVM LPAR and 4 GB on LPARs
running CPU intensive loads.
