SPSH4 Server SystemTechnical Product Specification

1. Introduction

This product specification details the features of the SPSH4 server system. Low cost, time to market, modularity, and utilization for multiple configurations are primary considerations in the design. The chassis has user friendly features and is accessible and serviceable.

The SPSH4 server system also incorporates features for high availablity servers. This includes power and cooling systems with optional redundancy, hot swap or easy to replace fans hot-plug PCI slots, and a mass storage system with hot-swappable hard drives. These are the key components for increasing availability of the server. Since the fans and power supplies typically have the lowest Mean Time Between Failure (MTBF) specifications, the optional redundancy of these components will permit the system to continue to operate with a failed fan or power supply. With the use of RAID technology the system can continue to operate with hard drive failures The hot-plug hard drives allow a failed hard drive to be replaced while the system continues to operate.

This product specification details the following:

 SPSH4 chassis features.

 Power supply subsystem.

 Chassis cooling.

 Front panel.

 System boards.

 I/O and interconnects.

 System configuration.

 System Certifications.

 Environmental limits.

 Reliability, serviceability, and availability.

SPSH4 Server Chassis Feature Overview SPSH4 Server System External Product Specification

2. SPSH4 Server Chassis Feature Overview

The SPSH4 MP server Chassis is 12.22 inches wide, 18.06 inches high, and 25.25 inches deep. The chassis is designed to be modular with a base unit with two easily removable units, one to hold the front panel and drive bays (C-tilt) and one to hold the baseboard, processor board and I/O panels (E-Bay). The Base section is U shaped and holds the power supplies and power distribution board. The E-bay drops in at the rear of the base unit and the C-tilt drops in from the front. The two captive screws in the front cover fasten both the E-bay and the C-tilt to the base unit. The E-bay fans are plugged in to a hot-swap fan holder and installed above the drives and infron to the E-bay. Three bays are supplied in the back of the chassis base unit for power supplies.

Figure 1 and Figure 2 show the system front view with both rack and pedestal bezel attached. The rack bezel has the standard color specific GE Cycoloy C6600-701 black. The pedestal bezel comes in two colors and has the standard color specific of GE Cycoloy C6600-701 black or GE Cycoloy C6600-BR7026 dusty beige. Only front panel status LEDs and chassis security lock are visible without opening bezel door. Figure 3 shows the system front view with the front bezel removed. Opening the front bezel door provides access to the following:

• Front panel control buttons

• One USB and one serial port

• Three 5¼” device bays (one 5¼” CD-ROM installed)

• One 3½” bay for a 1” floppy drive

• Two SCSI bays holding up to ten 1” hard drives

The SSH4 memory subsystem consists of a single memory expansion board. This board supports up to 12 DDR registered ECC SDRAM memory modules. The SSH4 baseboard implementation in SPSH4 server supports both stacked and unstacked memory modules for up to 24 GB of system memory.

The SSH4 boardset provides the following features:

• Three interleaved memory banks.

• Four 184 pin DIMMS per bank.

• Banks must be populated in order.

• Single bit error correction – If a single-bit error is detected, the ECC logic generates a new

Qword with a pattern that corresponds to the originally received 8-bit ECC parity code and returned to the requestor (the processor or the PCI master)

• Multi Bit error detection – Additional errors within the same Qword constitute a multibit error which may be unrecoverable. In the case of a multi-bit error, a non-maskable interrupt (NMI) is issued that instructs the system to shut down to avoid data corruption. ( multibit errors are very rare ).

• Memory Scrubbing – Error correction is performed on data being read from memory. The correction is the passed to the requestor and at the same time is “scrubbed” or corrected in

main memory. Memory scrubbing prevents the accumulation of single –bit errors in main memory tha would become unrecoverable mult-bit errors.

• Chipkill* - Chipkill is the ability of the memory system to wothstand a mult-bit failure within DRAM device, including a failure that causes incorrect data on all bits of the device.

3.2 Guidelines For Installing Memory in the SSH4 Server Board.

• Install only memory modules validated with this particular board. Refer to the Tested Hardware and Operating System List and/or Http:// support.intel.com.

• Bank 1 must be populated with Dimms first. See figure 9 above.

• All four Dimms within a bank must be identical

• Baseboard Management Controller (BMC) providing monitoring, alerting, and logging of

critical system information obtained from embedded sensors on baseboard

• 8 megabit Flash device for system BIOS

• Three externally accessible USB ports; two at rear bulkhead and one at front panel

• One IDE connector, supporting up to two ATA 66 compatible devices

4. Power supply Subsystem

This section defines the features and functionality of the SSI compliant 600 watt power supply, a universal input switching power supply. The power supplies are located in the power supply bay mounted near the rear of the chassis. The system may be configured either with two 600 W power supplies in a non-redundant configuration, or three 600 W power supplies for a redundant power (2 + 1) configuration. Each power supply requires an individual power cord. When the system is configured with three power supplies the following features are supported:

• The user can replace a failed power supply without interrupting system functionality under any loading condition.

• AC power to one of the power cords can be interrupted without loss of functionality.

Power from the power supply subsystem is carried to internal system boards and peripheral devices via discrete cables. Two 600 watt power supplies are capable of handling the worst case power requirements for a fully configured SPSH4 system. This includes four 75 watt Intel Xeon – MP processors, 24 GB of memory and ten hard drives at 20 watts per drive. Figure 8 shows the SPSH4 power supply.

!WARNING!

The total power requirement for the SPSH4 server system exceeds the

240VA energy hazard limit that defines an operator accessible area. As a

result, only qualified service personnel should access the processor,

memory, and non-hot plug I/O areas on the system baseboard while the

system is energized.

The following are the main features of the power supply subsystem:

• 1140 W output capability for two or three power supplies in full AC input voltage range

• Up to three 600 watt PFC power factor correcting power supplies for 2+1 power

• Integral handle for insertion/extraction

• Separate power cords for AC redundancy

The power supplies are populated in the chassis in a specific order as viewed from the rear of the server system. See Figure 9. For a rack configuration, the power supplies are installed from left to right. In a pedestal configuration the modules are installed from the bottom to the top. All of the power supplies implement blind mating connectors for easy installation. Each power supply implements two AC input fuses rated at 250V/15A, one for line and one neutral. Power supplies are not required to be on the same AC power phase. The power supply is held to the chassis frame with four 6-32 screws. These four screws and the AC cord must be removed to hot swap the power supply.

Figure 9: Rear view of SPSH4 Power Supply Bay

The power supply has four externally enabled outputs: +12V,+5V,+3.3V,-12V, and one +5VSB (standby) output. The +5VSB standby output is present whenever AC power is applied to any single power supply. The power supply has a minimum efficiency of 60% to its DC output pins at maximum load currents at rated nominal input voltages and frequencies.

Several LEDs on each power supply can be viewed from the rear of the server system. These indicate the power state for that particular module. Looking at the system from rear of the power supply, from left to right the LEDs are power, predictive fail, and fail.

Revision 1.11 Intel reference number 10736

Power supply Subsystem SPSH4 Server System External Product Specification

• The power LED is green and blinks to indicate that AC is applied to the power supply and +5VSB standby output voltage is available. This LED will turn a solid green to indicate the power supply is on and all the power output voltages are available.

• The predictive fail LED blinks amber LED and indicates the power supply will fail in the near future due to a poorly performing fan.

• The fail LED is amber and indicates that the power supply has experienced a failure of some type.

When the power supply configuration changes, the SDR utility must be run so that server management will properly monitor the new configuration.

A power LED on the front panel, labeled PWR, is green when power is applied to the system. Table 3 describes the conditions of the LEDs for the power supply.
