Reliability, Availability, And Serviceability; Ibm Director - IBM System x3800 Type 8865 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.
The server has the following RAS features:
v Active memory
v Active
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
v Baseboard management controller (service processor)
v Built-in, menu-driven electrically erasable programmable ROM (EEPROM) based
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Chipkill
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)
v Power-on self-test (POST)
v Predictive Failure Analysis
v Redundant Ethernet capabilities (requires optional Ethernet adapter) with failover
v Redundant hot-swap capability
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
v Upgradeable microcode for POST, BIOS, diagnostics, baseboard management
v Vital product data (VPD) on microprocessors, system boards, power supplies,
v Wake on LAN
