34 IBM Power 570 Technical Overview and Introduction
If the initial p5 570 server does not configure supported DDR2 memory, then the target 570
can be configured with FC 5622 processor card and the desired amount of memory must be
included in the model migration order.
Figure 2-7 Memory DIMM slots for FC 5621
A 570 with FC 5621 processor cards can be expanded by purchasing additional 570
enclosures with FC 5622 processor cards. FC 5621 and FC 5622 cannot be mixed within the
same 570 enclosure but can be mixed in the same system. Maximum memory configurable
depends from the number of FC 5621 and FC 5622 processor cards available in the fully
combined 570 system.
2.4.4 OEM memory
OEM memory is not supported or certified for use in IBM System p servers. If the 570 is
populated with OEM memory, you could experience unexpected and unpredictable behavior,
especially when the system is using Micro-Partitioning technology.
All IBM memory is identified by an IBM logo and a white label that is printed with a barcode
and an alphanumeric string, as illustrated in Figure 2-8 on page 35.
Important: The process to migrate a p5 570 to a 570 requires analysis of the existing
p5 570 memory DIMMs. Contact an IBM service representative before issuing the
configuration upgrade order.
