88 IBM Flex System p260 and p460 Planning and Implementation Guide

Use a minimum of 2 GB of memory per core. The functional minimum memory

configuration for the machine is 4 GB (two 2 GB DIMMs), but that is not sufficient

for reasonable production usage of the machine.

Low Profile and Very Low Profile form factors

One benefit of deploying IBM Flex System systems is the ability to use Low

Profile (LP) memory DIMMs. This design allows for more choices to configure the

machine to match your needs.

Table 4-5 lists the available memory options for the Power Systems compute

nodes.

DASD/local storage option dependency on memory form factor: Because

of the design of the on-cover storage connections, clients that seek to use

SAS HDDs

must use VLP DIMMs (4 GB or 8 GB). The cover is not able to

close properly if VLP DIMMs and SAS hard disk drives are configured in the

same system. However, solid-state drives (SSDs) and LP DIMMs can be

used together.
