What your server offers
The server uses the following features and technologies:
v Baseboard management controller (BMC)
The BMC provides basic service-processor environmental monitoring functions. If
an environmental condition exceeds a threshold or if a system component fails,
the BMC provides LEDs to help you diagnose the problem.
v High-performance graphics controller
The server comes with an onboard high-performance graphics controller that
supports high resolutions and includes many performance-enhancing features for
the operating-system environment.
v IBM Enhanced Diagnostics CD
The server comes with an IBM Enhanced Diagnostics CD, which you can use to
diagnose problems.
v IBM Director
IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage System x3400 servers. For more information, see the IBM
Director documentation on the IBM Director CD.
v IBM Enterprise X-Architecture technology
IBM X-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/servers/eserver/xseries/xarchitecture/
enterprise/index.html.
v IBM ServerGuide Setup and Installation CD
The ServerGuide Setup and Installation CD provides programs to help you set up
the server (some models) and install an operating system. The ServerGuide
™
program detects installed hardware options 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 81.
v Integrated network support
The server comes with an integrated Broadcom NetXtreme Gigabit Ethernet
controller, which supports connection to a 10-Mbps, 100-Mbps, or 1000-Mbps
network. For more information, see “Configuring the Broadcom Gigabit Ethernet
controller” on page 83.
v Large data-storage capacity and hot-swap capabilities
Hot-swap models support up to eight slim-high, 3.5-inch hot-swap hard disk
drives in the hot-swap bays. With the hot-swap feature, you can add, remove, or
replace hard disk drives without turning off the server.
v Large system-memory capacity
The server supports up to 32 GB (reduced to 16 GB in mirrored mode) of system
memory. The memory controller supports error correcting code (ECC) for up to
eight industry-standard, 2-way interleaved, x4 or x8, 1.8 V, 240-pin,
double-data-rate 2 (DDR2), PC2-5300, 677 MHz, dynamic random-access
memory (DRAM) fully buffered (FBD) dual inline memory modules (DIMMs).
v Memory mirroring
Some models support memory mirroring. Memory mirroring replicates and stores
data in DIMMs within two branches simultaneously. To support memory mirroring,
you must have at least two pairs of DIMMs installed (a pair in each branch).
Pairs of DIMMs that are next to each other (for example, DIMM slot 1 and DIMM
slot 4) within the channels of the same branch must be identical pairs of
