The Dell™ PowerEdge™ 6450 system, which supports up to four Intel
®
Pentium
®
III
Xeon™ microprocessors (and future generation Intel microprocessors), is a feature-
rich, enterprise class server that offers the highest performance, availability, scalability,
manageability, and investment protection features. The PowerEdge 6450 system pro-
vides a robust, reliable, rack-optimized platform on which large corporate customers
can deploy their mission critical applications.
This chapter describes the major hardware and software features of the computer
system, provides information about the indicators and controls on the system's front
panel, and discusses connecting external devices to the system.
The PowerEdge 6450 systems offer the following major features:

System Setup Program.”
The Pentium III Xeon processor includes MMX™ technology designed to handle
complex multimedia and communications software. This processor incorporates
new instructions and data types as well as a technique called single instruction,
multiple data (SIMD) that allows the processor to process multiple data elements
in parallel, thereby improving overall system performance.
A secondary (L2) cache of 512 kilobytes (KB), 1 megabyte (MB), or 2 MB of static
random-access memory (SRAM) is included within the single-edge contact (SEC)
cartridge that contains the processor. Math coprocessor functionality is internal
to the processor.
Support for symmetric multiprocessing (SMP) is available by installing up to three
more Pentium III Xeon processors. SMP greatly improves overall system perfor-
mance by dividing processor operations among the independent processors. To
take advantage of this feature, you must use an operating system that supports
