System Control

Close monitoring and control of the system environment and

hardware is done by the remote management console (RMC).

This logic also allows the system operator to monitor the sys-

tem from a remote location. The RMC logic is implemented

using a PIC17C44 microprocessor on the system board. The

RCM firmware code resides on the microprocessor and in

flash memory. The RMC is powered by an auxiliary 5V sup-

ply, so even when the system is powered off at the control

panel the RMC can be accessed—so long as the system is

plugged in.

The RMC provides the following monitoring and control

functions:

•

Monitors thermal sensors on the CPUs, the PCI

backplane, and the power supplies

•

Monitors voltages, power supplies, and fans

•

Handles hot swapping of power supplies and fans

•

Controls the control panel display and writes status

messages on the display

•

Detects alert conditions such as excessive temperature, fan

failure, and power supply failure and sends an alert

•

Shuts down the system if any fatal conditions exist

•

Records error log information in nonvolatile RAM on

each failing device

Storage

Removable media in the chassis includes a CD-ROM drive,

floppy diskette drive, and two 5.25 inch half-height bays,

which can be combined for one 5.25 inch full-height bay.

A disk cage in the front of the chassis supports up to four

Ultra2 SCSI disk drives (9.1 or 18.2 GB). The Ultra2 SCSI

drives are 1.6-inch 10,000 RPM. Another disk cage can be

added so that up to eight disks can be installed. Each cage

requires its own SCSI adapter.

The pedestal system can include up to three StorageWorks

shelves, each of which holds seven disks. In the rackmount

cabinet up to six StorageWorks shelves can be installed.

The StorageWorks shelves are 16-bit (wide) UltraSCSI;

UltraSCSI disks run at 7,200 RPM.

RAID (Redundant Array of Independent Disks)

The system can be configured with optional PCI RAID

controllers to organize disk data cost-effectively, improve

performance, and provide high levels of storage integrity.

Today, RAID is only available with StorageWorks shelves.

The optional RAID controllers have the following features:

•

Support for hot-swap drives

•

Automatic rebuild after hot swap

•

Console support for booting system from RAID

•

RAID levels 0, 1, 0+1, 5

•

Optional write cache

•

Optional read cache

•

Support for command queuing

Server Management

The AlphaServer products support important operational and

platform management requirements.

Operational Management

Server/Network Management. ServerWORKS Manager soft-

ware is included with each system. This software utilizes the

Simple Network Management Protocol (SNMP) environment

to assist the network or server administrator by constantly

monitoring the network for problems, thus avoiding expensive

downtime. The software monitors vital server information,

such as CPU and file system utilization, as well as the condi-

tion of the network supported by the management console.

Remote Server Management. The integrated remote

management console (RMC) lets the operator perform several

tasks from a serial console: monitor the system power,

temperature, and fans, and reset, halt, and power the system on

or off. The monitoring can be done locally or remotely through

a modem.

Platform Management

The AlphaServer ES40 systems support platform management

tasks such as manipulating and monitoring hardware perform-

ance, configuration, and errors. For example, the operating

systems provide a number of tools to characterize system per-

formance and display errors logged in the system error log file.

In addition, system console firmware provides hardware

configuration tools and diagnostics to facilitate quick hardware

installation and troubleshooting. The system operator can use

simple console commands to show the system configuration,

devices, boot and operational flags, and recorded errors. Also,

the console provides inventory support and configuration

management by giving access to serial numbers and revisions

of hardware and firmware.

Error Reporting

Compaq Analyze, a diagnostic service tool used to determine

the cause of hardware failures, is installed with the operating

systems. It provides automatic background analysis, as it

constantly views and reads the error log file. It analyzes both

single error/fault events and multiple events. When an error

condition is detected, it collects the error information and

sends it and an analysis to the user. The tool requires a

graphics monitor for its output display.

Security

•

Front doors can be locked to prevent access to the disk

drives and the rest of the system.

•

An interlock sensor switch shuts down power if the top

cover to the CPU/memory area is removed while power is

on.

•

Password protection is offered by the SRM console,

AlphaBIOS, and RMC.
