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 5464)
  • 24-hour support center
  • Automatic error retry and recovery
  • Automatic restart on nonmaskable interrupt (NMI)
  • Automatic restart after a power failure
  • Backup basic input/output system switching under the control of the Integrated Management Module 2.1 (IMM2.1)
  • Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy
  • Cable-presence detection on most connectors
  • Chipkill memory protection
  • Single-device data correction (SDDC) for x4 DRAM technology DIMMs (available on 16 GB DIMMs only). Ensures that data is available on a single x4 DRAM DIMM after a hard failure of up to two DRAM DIMMs. One x4 DRAM DIMM in each rank is reserved as a space device.
  • Diagnostic support for ServeRAID and Ethernet adapters
  • Error codes and messages
  • Error correcting code (ECC) L3 cache and system memory
  • Full Array Memory Mirroring (FAMM) redundancy
  • Hot-swap cooling fans with speed-sensing capability
  • Hot-swap hard disk drives
  • Hot-swap power supplies
  • Information and light path diagnostics LED panels
  • Integrated Management Module 2.1 (IMM2.1)
  • Light path diagnostics LEDs for DIMMs, microprocessors, hard disk drives, solid state drives, power supplies, and fans
  • Memory mirroring and memory sparing support
  • Memory error correcting code and parity test
  • Memory downsizing (non-mirrored memory). After a restart of the server after the memory controller detects a non-mirrored uncorrectable error and the memory controller cannot recover operationally, the IMM2.1 logs the uncorrectable error and informs POST. POST logically maps out the memory with the uncorrectable error, and the server restarts with the remaining installed memory.
  • Menu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration programs
  • 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)
  • Proactive Platform Alerts (including Predictive Failure Analysis and Self-Monitoring, Analysis and Reporting Technology alerts): microprocessors, voltage regulators, memory, internal storage (SAS/SATA hard disk drives and solid-state drives, NVMe solid-state drives, M.2 storage, flash storage adapters), fans, power supplies, RAID controllers, and server ambient and sub-component temperatures
  • Redundant Ethernet capabilities with failover support
  • Redundant hot-swap power supplies and redundant hot-swap fans
  • Redundant network interface card (NIC) support
  • Remote system problem-determination support
  • ROM-based diagnostics
  • ROM checksums
  • 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)
  • Solid-state drives
  • Standby voltage for systems-management features and monitoring
  • Startup (boot) from LAN through remote initial program load (RIPL) or dynamic host configuration protocol/boot protocol (DHCP/BOOTP)
  • System auto-configuring from the configuration menu
  • System-error logging (POST and IMM2.1)
  • Systems-management monitoring through the Inter-Integrated Circuit (I2C) protocol bus
  • Uncorrectable error (UE) detection
  • Upgradeable POST, Unified Extensible Firmware Interface (UEFI), diagnostics, IMM2.1 firmware, and read-only memory (ROM) resident code, locally or over the LAN
  • Vital product data (VPD) on microprocessors, system board, power supplies, and SAS/SATA (hot-swap hard disk drive or solid state drive) backplane
  • Wake on LAN capability
