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™ capability 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 Customer-upgradable basic input/output system (BIOS) code v DDR SDRAM with serial presence detect (SPD) and vital product data (VPD) 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 and redundant cooling with fan speed-sensing capability v Hot-swap and redundant power supplies v Hot-swap hard disk drives v Light path diagnostics v Memory mirroring v Microsoft Windows Server family failover support v Monitoring support for power-supply redundancy, 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 Remote Supervisor Adapter or Remote Supervisor Adapter II-EXA to enable remote server management 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 easier remote viewing) v Wake on LAN® capability 6 xSeries 445 Type 8870: User's Guide
