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.

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.

Table 1-7 Supported HMC models

Type-model Description

7310-C05 IBM 7310 Model C05 Deskside Hardware Management Console 7310-CR3 IBM 7310 Model CR3 Rack-Mount Hardware Management Console

Systems require Ethernet connectivity between HMC and one of the Ethernet ports of the service processor. Ensure that sufficient HMC Ethernet ports are available to enable public and private networks if you need both. The 7310 Model C05 is a deskside model with one 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.

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.

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

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.
