1.3.2 Memory features
The minimum memory requirement for the p5-520 and p5-520Q servers is 1 GB, and the
maximum capacity is 32 GB using 533 MHz DDR2 technology. The planar of each system
has eight sockets for memory DIMMs. Table 1-5 lists the available memory features.
Table 1-5 Memory feature codes
Note that an amount of memory is always in use by the Hypervisor, even when the machine is
not partitioned. You can use the System Planning Tool to calculate the amount of available
memory for an operating system based on machine configuration as follows:

1.3.3 Disk and media features
The minimum configuration includes a 4-pack disk drive enclosure. A second 4-pack disk
drive enclosure can be installed by ordering FC 6574 or FC 6594, so that the maximum
internal storage capacity can reach 2.4 TB (using the disk drive features available at the time
of writing). The p5-520 and p5-520Q feature up to eight disk drive bays, two slim-line media
device bays, and one half-height media bay. The minimum configuration requires at least one
disk drive. Table 1-6 shows the disk drive feature codes that each bay can contain.
