Reliability, Availability, And Serviceability - IBM System x3550 M3 Type 4254 Installation And User Manual

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:
v 3-year parts and 3-year labor limited warranty for machine type 7944 and 4-year
v Automatic error retry and recovery
v Automatic restart on nonmaskable interrupt (NMI)
v Automatic restart after a power failure
v Backup basic input/output system switching under the control of the Integrated
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Cable-presence detection on most connectors
v Chipkill memory protection
v Diagnostic support for ServeRAID and Ethernet adapters
v Error codes and messages
v Error correcting code (ECC) L2 cache and system memory
v Hot-swap cooling fans with speed-sensing capability
v Hot-swap hard disk drives
v Information and light path diagnostics LED panels
v Integrated Management Module (IMM)
v Menu-driven setup, system configuration, and redundant array of independent
v Microprocessor built-in self-test (BIST), internal error signal monitoring,
v Memory mirroring support (memory mirroring are mutually exclusive of each
v Parity checking on the small computer system interface (SCSI) bus and PCI
v Power management: Compliance with Advanced Configuration and Power
v Power-on self-test (POST)
v Predictive Failure Analysis (PFA) alerts on memory, SAS/SATA hard disk drives,
v Redundant Ethernet capabilities with failover support
v Redundant hot-swap power supplies and redundant hot-swap fans
v Redundant Network Interface Card (NIC) support
v Remind button to temporarily turn off the system-error LED
v Remote system problem-determination support
v ROM-based diagnostics
v ROM checksums
v Serial Presence Detection (SPD) on memory, VPD, power supply, and hard disk
v Single-DIMM isolation of excessive correctable error or multi-bit error by the
v Standby voltage for system-management features and monitoring
v Startup (boot) from LAN through remote initial program load (RIPL) or dynamic
v System auto-configuring from the configuration menu
v System-error logging (POST and IMM)
