5.4 IBM Flex System p260 and p24L Compute Nodes

The IBM Flex System p260 Compute Node and IBM Flex System p24L Compute Node are

based on IBM POWER architecture technologies. These compute nodes run in IBM Flex

System Enterprise Chassis units to provide a high-density, high-performance compute node

environment by using advanced processing technology.

This chapter describes the server offerings and the technology used in their implementation.

5.4.1 Specifications

The IBM Flex System p260 Compute Node is a half-wide, Power Systems compute node with

these characteristics:

򐂰 Two POWER7 processor sockets

򐂰 Sixteen memory slots

򐂰 Two I/O adapter slots

򐂰 An option for up to two internal drives for local storage

The IBM Flex System p260 Compute Node has the specifications shown in Table 5-46.

Table 5-46 IBM Flex System p260 Compute Node specifications

Remember: The IBM Flex System p260 Compute Node can be ordered only as part of

IBM PureFlex System as described in Chapter 2, “IBM PureFlex System” on page 11.

Components Specification

Model numbers 7895-22X.

Form factor Half-wide compute node.

Chassis support IBM Flex System Enterprise Chassis.

Processor Two IBM POWER7 processors. Each processor contains either eight cores (up

to 3.55 GHz and 32 MB L3 cache) or four cores (3.3 GHz and 16 MB L3 cache).

Each processor has 4 MB L3 cache per core. Integrated memory controller in

each processor, each with four memory channels. Each memory channel

operates at 6.4 Gbps. One GX++ I/O bus connection per processor. Supports

SMT4 mode, which enables four instruction threads to run simultaneously per

core.

Chipset IBM P7IOC I/O hub.

Memory 16 DIMM sockets. RDIMM DDR3 memory supported. Integrated memory

controller in each processor, each with four memory channels. Supports IBM

Active Memory™ Expansion with AIX 6.1 or later. All DIMMs operate at 1066

MHz. Both LP (low profile) and VLP (very low profile) DIMMs supported,

although only VLP DIMMs are supported if internal HDDs are configured. The

use of 1.8-inch solid-state drives allows the use of LP and VLP DIMMs.

Memory

maximums

256 GB using 16x 16 GB DIMMs.

Memory

protection

ECC, chipkill.

Disk drive bays Two 2.5-inch non-hot-swap drive bays that support 2.5-inch SAS HDD or

1.8-inch SATA SSD drives. If LP DIMMs are installed, only 1.8-inch SSDs are

supported. If VLP DIMMs are installed, both HDDs and SSDs are supported. An

HDD and an SSD cannot be installed together.

Maximum

internal storage

1.8 TB using two 900 GB SAS HDD drives, or 354 GB using two 177 GB SSD

drives.

RAID support RAID support by using the operating system.

Network

interfaces

None standard. Optional 1 Gb or 10 Gb Ethernet adapters.

PCI Expansion

slots

Two I/O connectors for adapters. PCI Express 2.0 x16 interface.

Ports One external USB port.

Systems

management

FSP, Predictive Failure Analysis, light path diagnostics panel, automatic server

restart, Serial over LAN support. IPMI compliant. Support for IBM Flex System

Manager, IBM Systems Director, and Active Energy Manager.

Security features Power-on password, selectable boot sequence.

Video None. Remote management by using Serial over LAN and IBM Flex System

Manager.

Limited warranty 3-year customer-replaceable unit and on-site limited warranty with 9x5/NBD.

Operating

systems

supported

IBM AIX, IBM i, and Linux.

Service and

support

Optional service upgrades are available through IBM ServicePacs: 4-hour or

2-hour response time, 8-hour fix time, 1-year or 2-year warranty extension,

remote technical support for IBM hardware and selected IBM and OEM

software.

Dimensions Width: 215 mm (8.5”), height: 51 mm (2.0”), depth: 493 mm (19.4”).

Weight Maximum configuration: 7.0 kg (15.4 lb).
