If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the
backup pair of DIMMs. For more information about installing DIMMs for memory mirroring, see
"Memory module installation" on page 55.
– Large system-memory capacity
The server supports up to a maximum of 512 GB of system memory. The server supports
only industry-standard double-data-rate 3 (DDR3) - 1600 MHz or 1866 MHz (depending on the
configuration), synchronous dynamic random-access memory (SDRAM) registered dual inline memory
modules (DIMMs) with error correcting code (ECC). For further details, see Problem Determination and
Service Guide on the System x Documentation CD.
• ServerGuide Setup and Installation CD
The ServerGuide Setup and Installation CD, which you can download from the web, provides programs to
help you set up the server and install a Windows operating system. The ServerGuide program detects
installed optional hardware devices and provides the correct configuration programs and device drivers.
For more information about the ServerGuide Setup and Installation CD, see "Using the ServerGuide
Setup and Installation CD" on page 85.
• Integrated network support
The server comes with an integrated 3-port Gigabit Ethernet controller, which supports connection to
a 10 Mbps, 100 Mbps, or 1000 Mbps network. For more information, see "Configuring the Gigabit
Ethernet controller" on page 98.
• Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores private and public secure
keys. It provides the hardware support for the Trusted Computing Group (TCG) specification.
You can download the software to support the TCG specification, when the software is available.
See http://www.ibm.com/servers/eserver/xseries/scalable_family.html for details about the TPM
implementation. You can enable TPM support through the Setup utility under the System Security
menu option.
• Large data-storage capacity and hot-swap capability
The hot-swap server models support a maximum of fourteen 3.5-inch hot-swap Serial Attached SCSI
(SAS) hard disk drives or hot-swap Serial ATA (SATA) hard disk drives.
With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.
• Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more information about the
light path diagnostics, see "Light path diagnostics" on page 113
• PCI adapter capabilities
Based on the server configuration, the server may possibly support up to three PCI expansion slots. See
"Installing an adapter on the PCI riser-card assembly" on page 42 for detailed information.
• Active Energy Manager
The Active Energy Manager solution is an Systems Director extension that measures and reports
server power consumption as it occurs. This enables you to monitor power consumption
in correlation to specific software application programs and hardware configurations. You
can obtain the measurement values through the systems-management interface and view
them, using Systems Director. For more information, including the required levels of Systems
Director and Active Energy Manager, see the Systems Director Information Center at
http://publib.boulder.ibm.com/infocenter/director/v6r1x/index.jsp?topic=/director_6.1/fqm0_main.html, or
see http://www-03.ibm.com/systems/software/director/resources.html.
• Redundant connection
The IMM2 provides failover capability to a redundant Ethernet connection with the applicable application
installed. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated
