32 IBM ^ Cluster 1600 Managed by PSSP 3.5: What’s New

2.4 The p650 server

This section describes the functionality and the features of the IBM pSeries p650

server (type 7038-6M2). The following topics are discussed in this section:

򐂰 An overview is given in 2.4.1, “Introduction to the p650 server” on page 32.

򐂰 The layout of the CPU board is described in 2.4.2, “CPU board layout” on

page 33.

򐂰 The design of the system board is outlined in 2.4.3, “System board design” on

page 34.

򐂰 Software considerations to obtain the full benefit of this machine are given in

2.4.4, “Software requirements” on page 35.

򐂰 Considerations for integrating the p650 into a Cluster 1600 are discussed in

2.4.5, “Cluster considerations” on page 35.

2.4.1 Introduction to the p650 server

The IBM pSeries p650 is a 2-, 4-, 6-, or 8-way SMP machine running the IBM

POWER4 microprocessor at 1.2 GHz or 1.45 GHz. It can be equipped with up to

64 GB of memory. The p650 is a rack server, suitable for installation, for example,

in a T42 rack. The 8U height allows up to five machines in a single rack. The

p650 includes seven PCI-X slots, six running at 133 MHz bus speed with a 64-bit

bus design, and the remaining slot is a 5V 32-bit slot at 133 MHz for compatibility.

Legacy 32-bit adapters are also supported. This is the first pSeries server where

the implementation of the POWER4-II chip is manufactured with higher density

and more registers. One integrated 10/100 Mbps Ethernet port and four serial

ports, as well as two HMC connections are already included. For enhanced RAS

features, a rack status beacon port is integrated. An integrated Ultra 320 SCSI

Controller and four bays for hot-swapable disk drives are included, allowing

internal storage of up to 587.2 GB. Furthermore, two auto-docking media bays

(DVD-ROM, DVD-RAM, CD-ROM, or tape drives) can be included and are

attached to the same SCSI bus. For usage as a full SMP server, no HMC needs

to be attached. If an HMC is connected, up to eight LPARs are possible with a

fully populated machine, four with a minimumly configured system.

Restriction: Please note, the p650 is not currently supported in a Cluster

1600. IBM intends to support it in the first half of 2003, as described in the

“Statement of Direction,” but this is subject to change without notice.

Attention: The number of LPARs you can create depends on the number of

different boot devices, CPUs, and memory.
