Scalability and memory expansion:
v Eight-socket scalability option uses
4 QPI external cables
v Multi-node configurations require 4
microprocessors in each node
v MAX5 memory expansion module
option uses four QPI ports
Note: When you add an optional
memory expansion module to your
server configuration and you plan
to use the optional USB flash
device with VMware EXSi
embedded hypervisor software, see
the documentation that comes with
the USB flash device and the
operation system installation
instructions for installing VMware
ESXi (or ESX, depending on your
enviroment) on your server at the
IBM websight at
http://www.ibm.com/systems/
support/. The documentation
provides additional installation and
configuration information that you
need to follow before you use the
memory expansion module.

What your server offers
The server uses the following features and technologies:
v UEFI-compliant server firmware
IBM UEFI firmware offers several features, including Unified Extensible
Firmware Interface (UEFI) 2.1 compliance; Active Energy Manager technology;
enhanced reliability, availability, and serviceability (RAS) capabilities; and basic
input/output system (BIOS) compatibility support. UEFI replaces the BIOS and
defines a standard interface between the operating system, platform firmware,
and external devices. UEFI-compliant System x
®
servers are capable of booting
UEFI-compliant operating systems, BIOS-based operating systems, and
BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server does not support DOS.

&brandind=5000008.
v Integrated management module
The integrated management module (IMM) combines service processor
functions, video controller, and remote presence and blue-screen capture features
in a single chip. The IMM provides advanced service processor control,
monitoring, and alerting function. If an environmental condition exceeds a
