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. The server has the following RAS features: v Active memory v Active™ PCI-X (hot-plug) adapter slots v Automatic BIOS recovery (ABR) v Automatic error retry and recovery v Automatic restart after a power failure v Availability of microcode and diagnostic levels v Backup basic input/output system (BIOS) switching under the control of the baseboard management controller v Baseboard management controller (service processor) v Built-in, menu-driven electrically erasable programmable ROM (EEPROM) based setup, system configuration, and diagnostic programs v Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy v Chipkill™ memory protection v Error codes and messages v Error correcting code (ECC) L2 cache and system memory v Fault-resistant startup v Hot-swap hard disk drives v IBM Director workgroup-hardware-management tool v Information and light path diagnostics LED panels v Optional service processor adapter for remote system management v Power managed and Advanced Configuration and Power Interface (ACPI) compliant v Power-on self-test (POST) v Predictive Failure Analysis® (PFA) alerts v Redundant Ethernet capabilities (requires optional Ethernet adapter) with failover support v Redundant hot-swap capability - Cooling fans with speed-sensing capability - Power supplies v Remind button to temporarily flash the attention LED v Remote system problem-determination support v ROM-based diagnostic programs v Standby voltage for systems-management features and monitoring v Startup (boot) from LAN using Preboot Execution Environment (PXE) protocol v System auto-configuring from the configuration menu v System error logging (POST and baseboard management controller when a Remote Supervisor Adapter II SlimLine is installed) v Upgradeable microcode for POST, BIOS, diagnostics, baseboard management controller, and read-only memory (ROM) resident code, locally or over the LAN v Vital product data (VPD) on microprocessors, system boards, power supplies, and SAS (hot-swap-drive) backplane v Wake on LAN® capability IBM Director With IBM Director, a network administrator can perform the following tasks: v View the hardware configuration of remote systems, in detail 6 IBM System x3800 Type 8865: User's Guide
