Configuring A Qpi Multi-Node System - IBM X3950 X5 Problem Determination And Service Manual

Configuring a QPI multi-node system

This topic provides information about configuring a QPI multi-node system.
About this task
A multi-node configuration interconnects multiple servers or multiple partitions.
This configuration requires 8 microprocessors and 16 memory cards (4
microprocessors and 8 memory cards per node). See the documentation that came
with your QPI cables to set up your QPI multi-node configuration.
Note: Do not use the IMM Scalable Partition Web Interface to configure a QPI
multi-node system.
Before you create scalable partitions, make sure that all the nodes in the
multi-node configuration contain the following software and hardware:
v
v Microprocessor that are the same cache size and type, and the same clock speed
Note: The nodes can vary in the number of microprocessors and the amount of
memory each contains, above the minimum.
