Feature Comment

Power system with redundancy The 750 watt, autoranging power supplies include integrated fans for

cooling. These power supplies operate at 100–120VAC or 200–240 VAC. When the server is configured with three supplies (2 + 1), the third provides redundancy. The supplies can be replaced— hot-swapped—without turning off server power. The server requires a minimum of two power supplies. LEDs on the back of the power supply indicate power on, failure, and predictive failure.

Server chassis The electrogalvanized metal used in manufacturing the server chassis

minimizes electromagnetic interference (EMI) and radio frequency interference (RFI).

The peripheral bay provides the interface for 3.5- and 5.25-inch media. It can support:

• One 5.25-inch IDE CD-ROM drive in the 5.25-inch half-height bay.

(Optional: any IDE or single-ended SCSI device, like a tape drive.)

• Two 3.5-inch wide by 1.0- or 1.6-inch hot-swappable low-voltage

differential SCSI (LVDS) hard disk drives mounted side-by-side in the 3.5-inch hot-swapping bays. These bays allow hot-swapping of hard disk drives without shutting down the server.

Ten hot-plug PCI I/O expansion slots.

The plastic front bezel provides airflow and easy access to drives in the hot-swapping bays. The removable top covers provide proper airflow and easy access to components inside the server. Only technically qualified personnel should remove the server covers.

Cooling system with redundancy Six fans (5 + 1) cool and circulate air through the server. The sixth fan

is redundant. The fans can be replaced—hot-swapped—without turning off server power. An LED indicator mounted next to each fan guarantees positive identification of the failed fan.

Integrated power supply fans—two or three—cool and circulate air through the power supplies and the bottom of the chassis.

Peripherals

The peripheral bay provides the interface for 3.5-inch and 5.25-inch media.

3.5-inch Diskette Drive

The 3.5-inch diskette drive in the peripheral bay supports 720 KB and 1.44 MB media. The drive is accessible from the front of the system and is located behind the front panel.

3.5-inch Hard Drive Bays

The peripheral bay contains two hot-swapping bays for two 3.5-inch-wide (1.0-inch high or 1.6-inch high) wide/fast-20 SCSI III SCA-type hard drives. The hard drives are accessible at the front of the system behind a secure front panel and connect to a wide LVDS hot-swap SCSI backplane.

As part of the hot-swap implementation, a drive carrier with an integral heatsink is required. The drives are mounted in the carrier with four fasteners and the carrier snaps into the chassis with a locking handle. A single metal EMI shield and plastic door cover the drive bays. A hot-swapping bay is provided for drives that are 3.5 inches wide and 1.0 or 1.6 inches high. Drives can consume up to 24 watts of power and must

be specified to run at a maximum ambient temperature of 40 ° C (104 °F).

5.25-inch Removable Media Device Bay

The peripheral bay has one 5.25-inch half-height bay that is accessible from the front of the system. This bay includes a CD-ROM drive used for software installation.

Note:

the installation of a hard disk drive is not recommended. Hard disk drives generate EMI (increasing ESD susceptibility), and this bay does not provide adequate cooling for a hard disk drive.

Hot-swap Power Supplies

The chassis can be configured with two or three 750-watt power supplies in a 2 + 1 redundancy configuration. If you have three supplies installed, you can hot-swap a failed supply without affecting system functionality. If you have two supplies installed, they must occupy the left and center bays (as you face the back of the server—see Figure 1-3). Each supply is designed to minimize EMI and RFI. This system is designed to operate at 100-120VAC or 200-240VAC.

The DC output voltages of each power supply are:

+3.3 V at 36.0 A max

+5 V at 36.0 A max (total combined output of +3.3 V and +5.5 V not to exceed

195 W)

1-8 System Overview

Boardset Description

The modular scaleable architecture of the rack server supports symmetrical multiprocessing (SMP) and a variety of operating systems. The server comes with Peripheral Component Interconnect (PCI) and Industry Standard Architecture (ISA) buses. ISA buses are used internally only. The system has no ISA slots or a way for the user to make use of the ISA bus. The server boardset consists of a set of printed circuit boards:

Profusion carrier



Processor mezzanine board(s)



Front side bus (FSB) terminator modules



Cache coherency filters

PCI hot-plug (PHP) I/O carrier



Low-voltage differential SCSI (LVDS) hot-swap disk backplane



I/O riser board

Two memory modules

Front panel controller board

Midplane

The profusion carrier is mounted horizontally toward the front of the chassis, and the PHP I/O carrier is mounted horizontally towards the rear of the chassis. The carriers plug into connectors on the midplane mounted between the two carriers. The midplane interconnects the carriers with the memory modules and power supplies. The front panel board is mounted in front of the profusion carrier in the same plane. This board provides the user interface, server management, cooling system control, and power control.

System Overview 1-11

Processor Overview

Each Intel Pentium III Xeon processor is packaged in a single edge contact (S.E.C.) cartridge. The cartridge includes:

The processor core with an integrated 32 KB primary (L1) cache

The secondary (L2) cache

A thermal plate

A back cover

Each processor implements the MMX™ technology with streaming SMID extensions and maintains full backward compatibility with the 8086, 80286, Intel386™, Intel486™, Pentium, and Pentium Pro processors. The processor's numeric coprocessor significantly increases the speed of floating-point operations and complies with ANSI/IEEE standard 754-1985.

Each S.E.C. cartridge connects to one of two processor mezzanine boards through a 330-pin Slot 2 edge connector (SC330.1). The cartridge is secured to the mezzanine carrier by a retention mechanism. Each mezzanine board connects to the profusion carrier. Depending on configuration, your system has one to eight processors.

The processor external interface is multiprocessor (MP)-ready and operates at 100 MHz. The processor contains a local APIC unit for interrupt handling in MP and uniprocessor (UP) environments.

The L2 cache is located on the same die as the processor core and L1 cache. The cache:

Is offered in 1 MB and 2 MB configurations

Is ECC protected

Operates at the full core clock rate

Memory Overview

Main memory resides on two add-in boards, called memory modules. Each memory module contains slots for 16 DIMMs and is attached to the profusion carrier through a 300-pin connector on the midplane. The memory controller supports PC 100-registered SDRAM DIMMs. Various DIMM sizes are supported, but each DIMM must be at least 128 MB. Memory amounts from 128 MB to 16 GB per module are supported. The ECC used for the memory module is capable of correcting single-bit errors (SBEs) and detecting 100% of double-bit errors over one code word. Nibble error detection is also provided.

You can install:

From 1 to 32 DIMMs (total number of DIMMs for two memory modules)

Equal number of DIMMs on each memory module (except when only one DIMM is

used)

1-12 System Overview

Note:

sizes on that module may vary, but when both memory modules are installed, the DIMM configuration on the two modules should be identical to support memory interleaving for performance gains.

When only a single memory module is installed, DIMM

Depending on how the memory modules are installed, the memory subsystem can operate in two different modes: interleaved and single-port.

Interleaved mode (two memory modules installed): The memory modules share a

common address range. One memory module responds to even-numbered cache lines, while the other responds to odd-numbered cache lines. This configuration offers the highest performance because it allows the two modules to be used in a balanced fashion, reducing address conflicts. To operate in interleaved mode, the

DIMMs must be installed in pairs (one on each module) and in the same locations on each module.

Single port mode (one memory module installed): The single memory module

responds to all memory addresses. The DIMMs on this single carrier need not be installed in pairs and can be installed one DIMM at a time.

DIMM Installation Sequence

A single carrier will support DIMM population in various configurations (empty sockets included). However, when fewer than 16 DIMMs are installed on a memory module, the preferred population order is to start from the lowest J number and populate sequentially to the highest. This recommendation helps maintain optimal signal integrity and thermal performance.

Note:

module installed. This increases to 32 GB with two modules.

Maximum capacity is limited to 16 GB with one memory

Some OSs and application programs use base memory while others use both conventional and extended memory. Examples:

Base memory: MS-DOS, OS/2, Windows NT, and UNIX

Conventional and extended memory: OS/2, Windows NT, and UNIX

MS-DOS does not use extended memory; however, some MS-DOS utility programs like RAM disks, disk caches, print spoolers, and windowing environments use extended memory for better performance.

BIOS automatically detects, sizes, and initializes the memory array, depending on the type, size, and speed of the installed DIMMs, and reports memory size and allocation to the system via configuration registers.

Peripheral Ports

Super I/O Chip

The 37C937 Super I/O device supports two serial ports, one parallel port, diskette drive, and PS/2-compatible keyboard and mouse. The system provides the connector interface for each port.

Serial Ports

Both serial ports are relocatable. By default, port A is physically the left connector (as you look at the back of the system — see Figure 1-3. Chassis Rear View), port B the right connector. Each serial port can be set to one of four different COMx ports, and each can be enabled separately. When enabled, each port can be programmed to generate edge- or level-sensitive interrupts. When disabled, serial port interrupts are available to add-in boards.

Parallel Port

The 25/15-pin connector stacks the parallel port over the VGA. The 37C937 provides one IEEE 1284-compatible 25-pin bi-directional EPP (supporting levels 1.7 and 1.9). BIOS programming of the Super I/O registers enables the parallel port and determines the port address and interrupt. When disabled, the interrupt is available to add-in boards.

Add-in Board Slots

The I/O carrier has ten 64-bit PCI buses (nine available) contained in four PCI segments. PCI slot 10 contains the system LAN controller board.

PCI-A provides for PCI slots 1 and 2 (33 MHz), dual-channel LVDS SCSI

controller, video, and PIIX4E.



The PIIX4E controls communications to IDE, onboard ISA, USB, and Super I/O

for handling the keyboard, mouse, diskette drive, parallel port, and serial ports.

PCI-B provides for PCI slots 3 through 6 (33 MHz).

PCI-C provides for slots 7 and 8 (two of the 66 MHz, 3.3 V slots).

PCI-D provides for slots 9 and 10 (the two other 66 MHz, 3.3 V slots).

Video

The onboard, integrated Cirrus Logic CL-GD5446 64-bit VGA chip contains an SVGA controller that is fully compatible with these video standards: CGA, EGA, Hercules Graphics, MDA, and VGA. The standard system configuration comes with 2 MB of 10 ns onboard video memory. The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 M colors.
