IBM's X-Architecture leverages proven innovative IBM technologies to build the
most powerful, scalable, reliable Intel-processor-based servers in the world.
X-Architecture includes features such as Light Path Diagnostics
®
Failure Analysis , and the Advanced System Management processor.
v Impressive performance using an innovative approach to SMP
The server supports up to two Pentium III microprocessors. The server comes
with one microprocessor installed; you can install an additional microprocessor
to enhance performance and provide SMP capability.
v Large system memory
The memory bus in the server supports up to 4 GB. The memory controller
provides error correcting code (ECC) support for up to four industry standard
PC133, 3.3 V, 168-pin, 8-byte, registered, synchronous-dynamic-random access
memory (SDRAM) dual inline memory modules (DIMMs). The memory
controller also provides Chipkill Memory protection. Chipkill Memory protection
is a technology that protects the system from a single chip failure on a DIMM.
The IBM Memory eXpansion Technology (MXT) chip on your server enables you
to store up to nearly twice the amount of data in system memory as was
previously possible. The MXT technology enables increased system performance
(through more available memory) without increasing system memory, or
comparable performance with half the memory. The level of increase
performance can depend on the number of applications running on the system
and the load on the system.
Notes:
1. An MXT device driver supporting the operating system might be required.

driver, or download and install the latest device driver from
http://www.ibm.com/pc/support/ on the World Wide Web. The Red Hat
®
Linux 7.2 operating system includes MXT support natively, and does not
need a separate device driver.
2. With non-MXT-aware operating systems, the system memory is limited to the
sum of the DIMMs installed.
3. On an MXT-aware Microsoft Windows operating system, MXT support
software limits Windows Address Windowing Extensions (AWE) allocations
to approximately one-half the physical memory size (one-fourth the MXT
memory). Because Windows AWE pages are nonpageable, this restriction
prevents user applications from running out of MXT memory. This is not a
problem for most applications.
4. Device drivers must limit the locked pages count to less than the physical
memory size. Most device drivers will operate with this restriction.
v System-management capabilities
The server comes with an Advanced System Management (ASM) processor on
the system board. This processor, in conjunction with the system-management
software that is provided with the server, enables you to manage the functions
of the server locally and remotely. The ASM processor also provides system
monitoring, event recording, and dial-out alert capability.
Note: The ASM processor is sometimes referred to as the service processor.
The optional IBM Remote Supervisor Adapter works in conjunction with the
integrated service processor to give you a World Wide Web interface to the
system-management functions. You can manage your server over the Internet or
intranet.
