IBM System p5 550 and 550Q Technical Overview and Introduction
Table 1-8 Processor card and processor activation feature codes (1.65 GHz QCM processor cards)
1.3.3 Memory features
The minimum memory requirement for the p5-550 or p5-550Q server is 1 GB, and the
maximum capacity is 64 GB when configured with two processor cards. 533 MHz DDR2
technology is used in the p5-550 or p5-550Q. The processor cards used in the p5-550 or
p5-550Q system have eight sockets for memory, DIMMs are shipped in pairs. Table 1-9 lists
the available memory features. Note that an amount of memory is always in use by the
Hypervisor, even when the machine is not partitioned. The IBM System Planning tool can be
used to calculate the amount of available memory for an operating system based on machine
configuration:

Table 1-9 Memory feature codes
It is recommended that each processor card have an equal amount of memory installed.
Balancing memory across the installed processor cards allows distributed memory accesses
that provide optimal performance. The memory controller detects a variety of memory
configurations of mixed memory sized DIMMs and DIMMs installed in pairs.
1.3.4 Disk and media features
The minimum p5-550 or p5-550Q configuration includes a 4-pack disk drive enclosure. A
second 4-pack disk drive enclosure can be installed by ordering FC 6592 or FC 6593;
therefore, the maximum internal storage capacity is 2.4 TB (using the disk drive features
available at the time of writing). The p5-550 or p5-550Q also features two slim-line media
device bays and one half-height media bay. The minimum configuration requires at least one
disk drive. Table 1-10 shows the disk drive feature codes that each bay can contain.
