• IBMX-Architecture technology: IBMX-Architecture technology combines proven, innovative IBM
designs to make your Intel-processor-based server powerful, scalable, and reliable. For more information,
see http://www.ibm.com/systems/x/hardware/enterprise/xarchitecture.html
– Active™ Memory: The Active Memory feature improves the reliability of memory through memory
mirroring. Memory mirroring mode replicates and stores data on two pairs of DIMMs within two
channels simultaneously. 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 "Installing a memory module" on page
– Remote presence capability and blue-screen capture: The remote presence and blue-screen
capture features are integrated functions of the Integrated Management Module (IMM) and are
available with the purchase of the optional IBM Virtual Media Key. A virtual media key is required to
enable the remote presence and blue-screen capture features. The remote presence feature provides
the following functions:
– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz, regardless of the
system state
– Remotely accessing the server, using the keyboard and mouse from a remote client
– Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping
ISO and diskette image files as virtual drives that are available for use by the server
– Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive
The blue-screen capture feature captures the video display contents before the IMM restarts the server
when the IMM detects an operating-system hang condition. A system administrator can use the blue-
screen capture to assist in determining the cause of the hang condition.
See "Using the remote presence capability and blue-screen capture" on page 114
information.
– Large system-memory capacity: The memory bus supports up to 192 GB of system memory when
registered DIMMs are installed. The server supports up to 48 GB if unbuffered DIMMs are installed. The
memory controller supports error correcting code (ECC) for up to 18 industry-standard PC3-10600R-
999, 800, 1067, and 1333 MHz, DDR3 (third-generation double-data-rate), synchronous dynamic
random access memory (SDRAM) dual inline memory modules (DIMMs).
• IBMServerGuide 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
• Integrated network support: The server comes with an integrated dual-port Broadcom 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
• 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 eight 2.5-inch hot-swap Serial Attached SCSI (SAS) hard disk drives or hot-swap Serial ATA
(SATA) hard disk drives. The simple-swap server models support a maximum of four 2.5-inch simple-
swap SATA hard disk drives.
With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.
