Reliability, Availability, And Serviceability Features - IBM xSeries 445 8870 User Manual

Reliability, availability, and serviceability features

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 your server, the availability of the computer when you need it, and the
ease with which you can diagnose and repair problems.
Your server has the following RAS features:
v Active Memory
v Active PCI-X (hot-plug) adapter slots
v Advanced Configuration and Power Interface (ACPI)
v Advanced Desktop Management Interface (DMI) features
v Advanced memory ECC, including Memory ProteXion, and multiple Chipkill
v Automatic error retry or recovery
v Auto-restart initial program load (IPL) power supply
v Automatic server restart
v Built-in, menu-driven Configuration/Setup Utility and diagnostic programs
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Customer-upgradable basic input/output system (BIOS) code
v Diagnostic support of Ethernet controllers
v Error codes and messages
v Error correcting code (ECC) protection on the L3 and XceL4 cache
v Failover Ethernet support
v Front-side buses (FSBs) parity protected
v Hot-add memory
v Hot-replace memory
v Hot-swap cooling with fan speed-sensing capability
v Hot-swap hard disk drives
v Light Path Diagnostics
v Memory mirroring
v Microsoft Windows Server family failover support
v Monitoring support for temperature, voltage, and fan speed
v Parity checking on the SCSI buses
v Power-on self-test (POST)
v Processor serial number access
v Read-only memory (ROM) checksums
v Redundant hot-swap
v Remote Supervisor Adapter to enable remote server management
v SDRAM with serial presence detect (SPD) and vital product data (VPD)
v Standard cable presence detection
v Standby voltage for systems-management features and monitoring
v System error logging
v Vital product data (VPD) (includes information stored in nonvolatile memory for
v Wake on LAN
