The Updatexpress System Pack Installer; Configuring A Multinode System - IBM System x3850 X6 Installation And Service Manual

The UpdateXpress System Pack Installer

This topic provides information about the UpdateXpress System Pack Installer
program.
The UpdateXpress System Pack Installer detects supported and installed device
drivers and firmware in the server and installs available updates. For additional
information and to download the UpdateXpress System Pack Installer, go to the
ToolsCenter for System x and BladeCenter at http://publib.boulder.ibm.com/
infocenter/toolsctr/v1r0/index.jsp and click UpdateXpress System Pack Installer.

Configuring a multinode system

This topic provides information about configuring a multinode system.
You can configure a multinode server into a single logical server or partition it into
two stand-alone partitions.
As a single logical server, the server is able to use resources from all scalable
partitions.
Note: When the server is configured as a single logical server, if there is an ac
system power failure to one of the nodes (partitions), the remaining good node
powers itself down and remains off until the failing node recovers from the ac
power loss. After the power is restored, both nodes will automatically turn on and
boot as a two-node partition.
In a stand-alone server, each scalable partition supports an independent
operating-system installation. In addition, each scalable partition uses its own
individual resources as an independent system. One stand-alone server cannot boot
an operating system on another stand-alone server.
The following is a list of the minimum components required to support the 8U
x3950 X6 configuration:
v Four DDR3 compute books (two in each node) with E7-8xxx v2 microprocessors.
The microprocessors must be of the same cache size, type, and clock speed.
v The 8-socket chassis
v Two standard I/O books
v Two storage books
v A minimum of four power supplies (two power supplies in each node)
Before you create a multinode system, make sure that all the nodes in the
multinode configuration contain the following software and hardware:
v The current level of UEFI firmware and IMM firmware (all nodes must be at the
same level)
v Microprocessors that are the same cache size, type, and clock speed
