In today's global-operation, information-driven business arena, enterprise servers are expected to
. .
be available around the clock, and the value of the data on those servers increases daily. As a
. .
. .
result, the cost of server downtime is increasingly prohibitive.
. .
. .
As a technology leader, Compaq continues to develop fault prevention, fault tolerance, and rapid
. .
recovery technologies that help make systems more reliable by eliminating single points of failure
. .
. .
and minimizing downtime when failure does occur.
. .
. .
This technology brief provides a brief overview of fault prevention, fault tolerance, and rapid
. .
recovery technologies as they are implemented in the following Compaq server subsystems:
. .
. .
Processor
. .
. .
Expansion
. .
. .
Memory
. .
Primary and secondary storage
. .
. .
Power
. .
Cooling
. .
. .
Management
. .
. .
An overview of the Compaq Pre-Failure Warranty is also included. Most sections contain
. .
. .
references to other Compaq white papers and technology briefs for more in-depth technical
. .
information about specific server subsystems.

Summary of Contents for Compaq ProLiant 1200

  • Page 1 As a result, the cost of server downtime is increasingly prohibitive. As a technology leader, Compaq continues to develop fault prevention, fault tolerance, and rapid recovery technologies that help make systems more reliable by eliminating single points of failure and minimizing downtime when failure does occur.
  • Page 2 This test is not a determination of product quality or correctness, nor does it ensure compliance with any federal state or local requirements. Change is Good, Compaq, Compaq Insight Manager and ProLiant are registered with the United States Patent and Trademark Office.
  • Page 3 Eliminating Single Points of Failure (cont.) N T R O D U C T I O N Compaq researches and develops server subsystems expressly to eliminate single points of failure and minimize downtime through fault-prevention, fault-tolerance, and rapid-recovery technologies. Compaq emphasizes reliability, along with performance and other critical characteristics, because the cost of system downtime is a pressing concern to businesses of every size and variety.
  • Page 4 Processor Without the Compaq approach to improved reliability, the server would come to an abrupt halt if a processor were to fail. To avoid this potential catastrophe, Compaq starts with top-quality components, then implements a number of redundancy schemes and addresses other factors that can cause processor failure, such as high temperature or an unstable power supply.
  • Page 5 Intel has licensed the Compaq PCI Hot Plug Controller for use on its system board products. All industry-standard PCI adapters can be used in Compaq’s hot plug environment without modification.
  • Page 6 Eliminating Single Points of Failure (cont.) All Compaq network device drivers have integrated error recovery features that allow the drivers to detect failure events and recover from these errors. The drivers can reset the NIC and continue running, usually without noticeable interruption, after the following types of errors: Adapter check interrupt: When the hardware detects a problem, a detailed console error message is generated and an immediate attempt to recover begins.
  • Page 7 Eliminating Single Points of Failure (cont.) Memory Compaq includes ECC memory in its servers to provide protection from memory errors in main system memory. The ECC memory scheme delivers superior error detection and correction capabilities, providing a greater level of data integrity for all network environments.
  • Page 8 RAID arrays connected to a single controller by mating two SMART-2 Array Controllers as a controller pair. This combination of hardware and software, developed by Compaq, sits idle in the background under Windows NT and provides failover protection for pairs of SCSI controllers. One controller is active, while the other remains in standby mode.
  • Page 9 RAID configurations). Backup applications that do not support RAIT configurations, such as Seagate Backup Exec and Legato Networker, can also be run with Compaq DLT Arrays. When used in RAIT configuration, the DLT Array stripes data across the drives and creates parity records, which can be used to rebuild data on a failed tape/drive.
  • Page 10 On the Compaq ProLiant 6000, 6500, and 7000 servers, power supplies can be arranged in an n+1 configuration, where n equals the number of power supplies required to run the system. Power supplies share the load;...
  • Page 11 Power Supply, see technology brief ECG025.0897, Intelligent Power Supply. The Compaq UPS provides temporary power to the server in the event of a power interruption and prevents the loss of critical data by allowing the server to be gracefully shut down. Its Enhanced Battery Management feature prolongs the life of the battery while monitoring the battery’s charge...

  • Page 12: Integrated Remote Console

    The Integrated Remote Console works through Compaq Insight Manager, and its capabilities can be expanded with the addition of the optional Remote Insight Board. For more information about the Integrated Remote Console, please refer to white paper 582A/1096, Remote Server Management with Integrated Remote Console.
  • Page 13 The Pre-Failure Warranty is standard on all Compaq servers using Compaq Insight Manager 2.0 or later; it applies to Error Checking and Correcting (ECC) memory, Pentium Pro and Pentium II processors, server hard drives (including the Compaq IDA, IDA-2, and SMART Wide-Ultra SCSI-3 drives) and any Compaq drives attached to array controllers, as well as SMART SCSI Array Controllers.
