IBM Flex System V7000 Storage Node Introduction and Implementation Guide

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, using advanced processing technology. The IBM Flex System p24L Compute 
Node shares several similarities to the IBM Flex System p260 Compute Node in that it is a 
half-wide, Power Systems compute node with two POWER7 processor sockets,16 memory 
slots, two I/O adapter slots, and an option for up to two internal drives for local storage. The 
IBM Flex System p24L Compute Node is optimized for lower-cost Linux installations. 

The IBM Flex System p260 Compute Node has the following features:

��

Two processors with up to 16 POWER7 processing cores, up to 8 per processor

��

Sixteen DDR3 memory DIMM slots supporting Active Memory™ Expansion

��

Supports VLP (Very Low Profile) and LP (Low Profile) DIMMs

��

Two P7IOC I/O hubs

��

RAID-compatible SAS controller supporting up to 2 SSD or HDD drives

��

Two I/O adapter slots

��

Flexible Support Processor (FSP)

��

System management alerts

��

IBM Light Path Diagnostics

��

USB 2.0 port

��

IBM EnergyScale™ technology

The front panel of Power Systems compute nodes has the following common elements, as 
shown in Figure 1-11.
