Reliability, availability, and serviceability features

Three of the most important features in server design are reliability, availability, and serviceability (RAS). These RAS features help to ensure the integrity of the data that is stored in the blade server, the availability of the blade server when you need it, and the ease with which you can diagnose and correct problems.

The blade server has the following RAS features:

  • Customer upgrade of flash ROM-resident code and diagnostics
  • Power policy 24-hour support center
  • Vital product data (VPD) on memory
  • Processor presence detection
  • Advanced Configuration and Power Interface (ACPI)
  • Automatic server restart (ASR)
  • Built-in diagnostics using DSA Preboot, which is stored in integrated USB memory.
  • Built in monitoring for temperature, voltage, and hard disk drives
  • Customer support center 24 hours per day, 7 days a week.1
  • Customer-upgradeable Unified Extensible Firmware Interface (UEFI) code and diagnostics
  • ECC protection on the L2 cache
  • Error codes and messages
  • Integrated management module (IMM)
  • Light path diagnostics
  • Memory parity testing
  • Registered ECC DDR3 memory
  • Microprocessor built-in self-test (BIST) during power-on self-test (POST)
  • Microprocessor serial number access
  • PCI PMI 2.2
  • PCI Express 1.0a
  • POST
  • ROM-resident diagnostics
  • Service processor that communicates with the advanced management module to enable remote blade server management
  • System-error logging
  • Wake on LAN capability
  • Wake on PCI (PME) capability
  • Wake on USB 2.0 capability
1 Service availability varies by country. Response time varies depending on the number and nature of incoming calls.
