6 IBM System p5 520 and 520Q Technical Overview and Introduction
AIX 5L system tools for configuration management if the adapter is connected to a common
maintenance console, such as the 7316-TF3 rack-mounted flat-panel display.
1.3 Minimum and optional features
The systems are based on a flexible, modular design based on POWER5+ processors. The
server is available in 1-core, 2-core, and 4-core configurations that feature the following:
1.65 (SCM and DCM), 1.9 or 2.1 GHz (DCM), and 1.5 or 1.65 GHz (QCM) POWER5+
processors.
From 1 GB to 32 GB of total system memory capacity using 533 MHz DDR2 DIMM
technology.
Four SCSI disk drives in a minimum configuration, eight SCSI disk drives with an optional
second 4-pack enclosure for a total internal storage capacity of 2.4 TB using 300 GB disk
drives.
Six PCI-X slots (one 266 MHz 64-bit PCIX-2, three 133 MHz 64-bit PCI-X, two 66 MHz
32-bit PCI-X). All slots support Enhanced Error Handling (EEH).
Two slim-line media bays for optional storage devices.
One half-high bay for an optional tape device.
The p5-520 and p5-520Q, including the service processor that is described in 3.2.1, “Service
processor” on page 83, support the following native ports:
Two 10/100/1000 Ethernet ports on a single controller
Two system ports
Two USB 2.0 ports on a single controller
Optionally, an external USB diskette drive 1.44 (FC 2591) is available.
Two HMC ports
Optional GX+ Bus to RIO-2 adapter card (FC 2888)
Two SPCN ports
In addition, the p5-520 and p5-520Q feature one internal Ultra320 SCSI dual channel
controller, redundant hot-swap power supply (optional), and cooling fans.
The system supports 32-bit and 64-bit applications and requires specific levels of AIX 5L and
Linux operating systems. For more information, see 2.14, “Operating system support” on
page 64.
1.3.1 Processor features
The p5-520 features one or two POWER5+ processors, each with one or two cores running at
1.65 GHz, 1.9 GHz, or 2.1 GHz, or the p5-520Q with four cores running at 1.5 GHz or
1.65 GHz. The processors are installed on either single-core modules (SCM), dual-core
modules (DCM), or quad-core modules (QCM). The POWER5+ processor modules are
mounted directly to the system planar. Table 1-4 on page 7 lists the available processor
features.
