Reliability, availability, and serviceability

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

Your server has the following RAS features:
  • 3-year parts and 3-year labor limited warranty (Machine Type 5458)
  • Backup basic input/output system switching under the control of the Integrated Management Module II (IMM2)
  • Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy
  • Chipkill memory protection
  • Diagnostic support for ServeRAID and Ethernet adapters
  • Error codes and messages
  • Error correcting code (ECC) L3 cache and system memory
  • Cooling fans with speed-sensing capability
  • Hot-swap hard disk drives
  • Hot-swap power supplies
  • Information and light path diagnostics LED panels
  • Light path diagnostics LEDs for DIMMs, microprocessors, and power supplies
  • Memory error correcting code and parity test
  • Microprocessor built-in self-test (BIST), internal error signal monitoring, internal thermal trip signal monitoring, configuration checking, and microprocessor and voltage regulator module failure identification through light path diagnostics
  • Nonmaskable interrupt (NMI) button
  • Parity checking on the PCIe buses
  • Power management: compliance with Advanced Configuration and Power Interface (ACPI)
  • Power-on self-test (POST)
  • Redundant hot-swap power supplies
  • Serial Presence Detection (SPD) on memory, VPD on system board, power supply, and hard disk drive or solid state drive backplanes, microprocessor and memory expansion tray, and Ethernet adapters
  • Single-DIMM isolation of excessive correctable error or multi-bit error by the Unified Extensible Firmware Interface (UEFI)
  • Upgradeable POST, Unified Extensible Firmware Interface (UEFI), diagnostics, IMM2 firmware, and read-only memory (ROM) resident code, locally or over the LAN
