Introduction:Dell™PowerEdge™6400SystemsUser'sGuide

Overview

The Dell PowerEdge 6400 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 6400 system provides a robust, reliable, rack-optimized platform on which large corporate

customers can deploy their mission critical applications.

This section 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.

System Features

The PowerEdge 6400 systems offer the following major features:

l One to four Intel Pentium III Xeon processors with an internal operating frequency of 550 megahertz (MHz) and an external bus speed of 100

MHz.

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.

l 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.

l Support for symmetric multiprocessing (SMP) is available by installing up to three more Pentium III Xeon processors. SMP greatly improves

overall system performance by dividing processor operations among the independent processors. To take advantage of this feature, you

must use an operating system that supports multiprocessing, such as Microsoft®Windows NT®4.0 or Novell®NetWare®4.2 (and later

versions of both).

l A minimum of 256 MB of system memory, upgradable to a maximum of 8 gigabytes (GB) by installing combinations of 64-, 128-, 256-, and

512-MB synchronous dynamic RAM (SDRAM) in the 16 dual in-line memory module (DIMM) sockets on the memory board.

l A basic input/output system (BIOS) that resides in flash memory on the Peripheral Component Interconnect (PCI) bus and can be upgraded if

required.

l Three small computer system interface (SCSI) backplane options:

¡ A six-slot SCSI backplane board allows the option of six hot-pluggable, 1- or 1.6-inch SCSI hard-disk drives.

¡ An eight-slot SCSI backplane board allows for eight hot-pluggable, 1-inch SCSI hard-disk drives. (This backplane board can be

configured as a 2 x 4 split backplane for internal duplexing of hard-disk drives).

¡ A two-slot backplane board allows for two optional, hot-pluggable, 1-inch drives that can be installed in the removable media bay.

l Three redundant, hot-pluggable power supplies and power-supply paralleling board (PSPB).

l Five redundant system cooling fans.

The system board includes the following integrated features:

l Seven PCI connectors; two 64-bit 66 MHz, four 64-bit33MHz,andone32-bit 33 MHz.

l A video graphics array (VGA)-compatible video subsystem with an ATI Rage IIc super VGA (SVGA) video controller. This video subsystem

NOTE: If you decide to upgrade your system by installing additional processors, you must order processor upgrade kits from

Dell. Not all versions of the Pentium III Xeon processor will work properly as additional processors. The upgrade kit from Dell

contains the correct version of the processor for use as an additional processor, as well as instructions for performing the

upgrade. The additional processors must have the same internal operating frequency as the initial processors.

NOTE: A minimum of two power supplies are needed to run the system.
