xii IBM System p5 520 and 520Q Technical Overview and Introduction

Chapter 1. General description

The IBM System p5 520 and IBM System p5 520Q rack-mount and deskside servers
(9131-52A) give you new tools for managing on demand business, greater application
flexibility, and innovative technology in 1-core, 2-core, and 4-core configurations — all
designed to help you capitalize on the on demand business revolut ion. To simplify naming,
both products are referred to as

The p5-520 and p5-520Q have POWER5+™ processors which provide performance and
reliability advances (or enhancements) over the POWER5™ architecture that it replaces.
Chief among the enhancements is 90 nm processor fabrication technology.

p5-520 or p5-520Q.

1

The p5-520 processor is packaged as a 1-core single-core module running at 1.65 GHz with
no L3 cache or as a 1-core single-core module running at 2.1 GHz with 36 MB of L3 cache or
a 2-core dual-core module running at 1.65 or 1.9 or 2.1 GHz with 36 MB of L3. The p5-520Q
offers the same features but comes with a 4-core POWER5+ quad-core module running at

1.5 or 1.65 GHz with two 36 MB of L3 caches.
When you purchase a p5-520 or p5-520Q Express Product Offering that is only available on

an initial order request, you might qualify for processor activation at no extra charge. The
number of processors, total memory, quantity and size of disk, and the presence of a media
device are the only f eatures that determine if you are en titled to a processor entitlement at no
additional charge. Contact your marketing representative regarding the feature for Express
Product Offering or volume offering.

The p5-520 and p5-520Q server have a base of 1 GB of DDR2 memory that can be
expanded to 32 GB, designed for performance and exploitation of 64-bit addressing as used
in large database applications.

The p5-520 and p5-520Q include four front-accessible, hot-swap capable disk bays in a
minimum configuration with an additional four hot-swap capable disk bays as an optional
feature. The e ight disk bays can accommodate up to 2.4 TB of disk stor age u sing the 300 GB
Ultra320 SCSI disk drives. Other features included in the p5-520 and p5-520Q are six
hot-plug PCI-X slots with Enhanced Error Handling (EEH), integrated service processor,
integrated 10/100/1000 Mbps two-port Ethernet, two system, two USB, and two Hardware
Management Console (HMC) ports, integrated dual-channel Ultra320 SCSI controller,
hot-swappable power and cooling, and optional redundant power.

Three non-hot-swappable media bays ar e used to accommodate additional devices . Two
media bays only accept slim-line media de vices, such as DVD-ROM or DVD-RAM drives, and
one half-height bay is used for a tape drive. The rack-mount model also has I/O extension
capability using the RIO-2 bus that allows attachment of the 7311 Model D20 I/O drawers.

For partitioning, we recommend an HMC. Dynamic LPAR is supported on the p5-520 and
p5-520Q servers, allowing up to two logical partitions. In addition, the optional Advanced
POWER™ Virtualization feature supports up to 40 micro-partitions using Micro-Partitioning™
technology. The Integrated Virtualization Manager provides partition management in settings
where an HMC is unavailable or not desired.

Additional reliability and availability features include redundant hot-swappable cooling fans
and redundant power supp lies. Along with these components, the p5-520 and p5-520Q are
designed to provide an extensive set of reliability, availability, and serviceability (RAS)
features that include a dual service processor, fault isolation, recovery from errors without
stopping the system, avoidance of recurring failures, and predictive failure analysis.

The p5-520 and p5-520Q are backed by a three-year limited warranty. Check with your IBM
representative for particular warranty availability in your region.

1.3.6 Hardware Management Console models

A p5-520 or p5-520Q can be either HMC-mana ged or non-HMC-ma naged. In HMC-ma naged
mode, an HMC is required as a dedicated workstation that allows you to configure and
manage partitions. The HMC provides a set of functions to manage the system LPARs,
dynamic LPAR operations, virtual features, Capacity on Demand, inventory and microcode
management, and remote pow er cont rol functio ns. These functions also include the handling
of the partition profiles that define the processor, memory, and I/O resources allocated to an
individual partition. For detailed information about the HMC, see 2.13, “Hardware
Management Console” on page 60.

Note: Non-HMC-managed modes are full system partition modes, where only o ne partition
contains all system resources that exist on the system. For more information about using
the Integrated Virtualization Manager (IVM), see 2.12.5, “Integrated Virtualization
Manager” on page 57.

Table 1-7 lists the HMC options for POWER5 processor-based systems that are available at
the time of writing. You can also use existing HMC models.

native 10/100/1000 Ethernet port. It can be extended with two additional two-port
10/100/1000 Gb adapters. The 7310 Mod el CR3 is a 1U, 19-inch rack mou nt able drawer that
has two native Eth ernet ports and can be e x te nd ed wit h one ad dit ion al t w o- po rt 10/100/1000
Gb adapter.

In HMC-managed installations with very high demand for high availability, you should
consider deployment of tw o HMCs. The service processor allows for conne ction of two HMCs ,
and there is no need for special handli ng of a dual HMC environment. HM Cs provide a loc king
mechanism so that only one HMC has write access to the service processor at a time.

When an HMC is connected to the system, the integrated system ports are disabled.
To support a non-Ethernet HACMP™ heartbeat, you need to provide an asynchronous

adapter (FC 5723 or FC 2943).

Note: It is not possible to connect POWER4™ with POWER5 or POWER5+
processor-based systems simultaneously to the same HMC. However, it is possible to
connect POWER5 and POWER5+ processor-based systems together to the same HMC.

1.4 Express Product Offerings

The Express Product Offerings provide a convenient way to order any of several
configurations that are designed to meet typical client requirements. Special reduced pricing
is available when a system order satisfies specific configuration requirements for memory,
disk drives, and processors.

1.4.1 Express Product Offerings requirements

When you order an Express Product Offering, the configurator offers a choice of starting
points onto which you can add. You can configure systems with one or two processor cards
and two or four proce ssor activations.

With the purchase of an Express Product Offering, f or each paid processor activ ation, you are
entitled to one processor activation at no additional charge, if the following requirements are
met:

򐂰 The system must have at least two disk drives of at least 73.4 GB each.
򐂰 There must be at least 2 GB of memory installed for each active processor.

If you order a p5-520 server Express Product O ff ering as defined here , y ou might qu alify f or a
processor activation at no extra charge. The number of processors, total memory, quantity
and size of disk, and presence of a media device are the only features that determine if a
client is entitled to a processor entitlement at no additional charge.

When you purchase an Express Product Offering, you are entitled to a lo wer priced AIX 5L or
Linux operating system license, or you can choose to purchase the system with no operating
system. The lower priced AIX 5L or Linux oper ating system is proces sed via a f eature number
on AIX 5L and either Red Hat or SUSE Linux. You can choose either the lower priced AIX 5L
or Linux subscription, but not both.

If you choose AIX 5L for your lo wer priced operating system, y ou can also order Linux b ut will
purchase your Linux subscription at full price versus the reduced price. The same is true if
you choose a Linux subscription as your lower priced operating system. Systems with a
reduced price AIX 5L offering are the IBM System p5 Express Product Offering, AIX 5L
edition. Systems with a lower priced Linux operating system are referred to as the
IBM System p5 Express Product Offering, OpenPower™ edition. In the case of Linux, only
the first subscription purchased is lower priced. So, for exa mple, additional licenses
purchased for Red Hat to run in multiple partitions will be at full price.

You can make changes to the standard features as needed and still qualify for processor
entitlements at no additional charge and a reduced price AIX 5L or Linux operating system
license.

If the system was initially ordered as an Express Product Offering, the system can be
expanded at a later time using Express Product Offering pricing, when additional processors
and activations along wit h the required memory are ordered on the same hardware upgrade
order. The upgraded p5-520Q configuration must satisfy the Express Product Offering
requirements for disk drives, memory, and processors. However, if the selection of total
memory or disk drives is smaller than the total defined as the minimums, it disqualifies the
order as an Express Product Offering.

1.4.2 Configurator starting points for Express Product Offerings

All Express Product Offerings have a set of standard features for the rack-mounted or
deskside versions as listed in Table 1-8 on page 12.

The IBM 7014 Model S11, S25, T00, and T42 Racks are 19-inch racks for general use with
IBM System p and OpenPower Edition rack-mount servers. The racks provide increased
capacity, greater flexibility, and improved floor space utilization.

12 IBM System p5 520 and 520Q Technical Overview and Introduction

If a server is to be installed in a non-IBM rack or cabinet, you must ensure that the rack
conforms to the EIA

2

standard EIA-310-D (see 1.5.9, “OEM rack” on page 21).

Note: It is the client’s responsibility to ensure that the installation of the drawer in the
preferred rack or cabinet results in a configuration that is stable, serviceable, safe, and
compatible with the drawer requirements for power, cooling, cable management, weight,
and rail security.

The S25 rack has a maxim um load limit of 22.7 kg ( 50 lb.) per EIA unit f or a ma xim um loaded
rack weight of 667 kg (1470 lb.).

1.5.5 S11 rack and S25 rack considerations

The S11 and S25 racks d o not h ave vertical mounting space that will accommodat e F C 71 88
PDUs. All PDUs required for application in these racks must be installed horizontally in the
rear of the rack. Each horizontally mounted PDU occupies 1U of space in the rack, and
therefore reduces the space available for mounting servers and other components.

FC 0469 Customer Specified Rack Placement provides the ability to specify the physical
location of the system modules and attached expansion modules (drawe rs) in the racks. The
client’s request is reviewed by eConfig for safe handling by checking the weight distribution
within the rack. The Manuf a cturing Plant provides the fin al approv al f or the co nfiguration. Th is
information is then used by IBM Manufacturing to assemble the system components
(drawers) in the rack according to the client’s request.

The CFReport from eConfig must be submitte d to the following site:

1.5.6 The ac power distribution unit and rack content

Note: Each server, or syst em dr a wer to be mounted in the rack, r equire s tw o power cords,

which are not included in the base order. For maximum availability, we highly recommend
that you connect po wer cords from the same server or system drawer to two separate
PDUs in the rack. These PDUs could be connected to two independent client power
sources.

For rac k models T00 and T42, 1 2-outlet PDUs (FC 9188 and FC 7188) are ava ilable . F or r ack
models S11 and S25, FC 7188 is available.

Four PDUs can be mounted vertically in the T00 and T42 racks. See Figure 1-4 on page 17
for the placement of the four vertically mounted PDUs. In the rear of the rack, two additional
PDUs can be installed horizontally in the T00 rack and three in the T42 rack. The four vertical
mounting locations will be filled first in the T00 and T42 racks. Mounting PDUs horizontally
consumes 1U per PDU and reduces the space av ailable for other racked components. When
mounting PDUs horizontally, we recommend that you use fillers in the EIA units occupied by
these PDUs to facilitate proper air flow and ventilation in the rack.
