Configuring A Qpi Muliti-Node System - IBM System x3850 X5 Installation And User Manual

3. Connect and log in to the IMM web interface.
4. In the navigation pane, click Manage Partition(s) under Scalable Partitioning.
Note: Click Redraw to reorder the sequence in which the nodes appear in the
diagram on the page. For example, you can reorder the diagram to reflect the
order in which the nodes are installed in a rack. The nodes are reordered according
to the QPI or EXA cabling, with the node that you select in the top position.

Configuring a QPI muliti-node system

A multi-node configuration interconnects multiple servers or multiple partitions.
This configuration requires 8 microprocessors and sixteen 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.
Before you create scalable partitions, read the following information:
v Make sure that all the nodes in the multi-node configuration contain the
112
IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide
operate independently. On the Scalable Complex Management page, click Force
under Standalone Boot to enable the Standby mode.
Use the Scalable Complex Management page to create, delete, control, and view
scalable partitions. Select the primary node; then, automatically or manually
create a scalable partition:
v Click Auto under Partition Configure to automatically create a single
partition that uses all nodes in the multi-node configuration.
v Click Create under Partition Configure to manually assign nodes to the
partition.
following software and hardware:
– The current level of UEFI code, SAS UEFI code, IMM firmware, and FPGA
firmware
Note: To check for the latest firmware levels and to download firmware
updates, go to http://www.ibm.com/systems/support/.
– Microprocessors that are the same cache size and type, and the same clock
speed.
