Reliability, availability, and serviceabilityThree important server design features are reliability, availability, and serviceability(RAS). The RAS features help to ensure the integrity of the data that is stored inthe server, the availability of the server when you need it, and the ease with whichyou can diagnose and correct problems.The server has the following RAS features:v Advanced memory features:– Single-bit memory error detection– Single-bit memory error hardware correction– Multi single-bit memory error recovery and corrections– Uncorrectable error (UE) detection– Full array memory mirroring (FAMM) redundancy– Automatic failover recovery for UEs when FAMM is configured– Automated logical removal of failed DIMMs on reboots prior to replacement– Automatic address parity checking during writes and readsv Automatic BIOS recovery (ABR) for UEFIv Automatic error retry and recoveryv Automatic restart after a power failurev Availability of microcode and diagnostic levelsv Integrated baseboard management controller (service processor)v Built-in, menu-driven electrically erasable programmable ROM (EEPROM) basedsetup, system configuration, and diagnostic programsv Built-in monitoring for fan, power, temperature, voltage, and power-supplyredundancyv Error codes and messagesv Error correcting code (ECC) L2 cache and system memoryv Fault-resistant startupv Hot-swap hard disk drivesv IBM Systems Director workgroup-hardware-management toolv Information and light path diagnostics LED panelsv Service processor adapter for remote systems managementv Parity checking on the SAS bus and PCI Express busesv Power managed and Advanced Configuration and Power Interface (ACPI)compliantv Power-on self-test (POST)v Predictive Failure Analysis (PFA) alertsv Redundant hot-swap capability– Cooling fans with speed-sensing capability (depending on the model)– Power suppliesv Remind button to temporarily flash the system-error LEDv Remote system problem-determination supportv ROM-based diagnostic programsv Standby voltage for systems-management features and monitoringv Startup (boot) from LAN using Preboot Execution Environment (PXE) protocolv System auto-configuring from the configuration menuv System error loggingv Upgradeable microcode for POST, iBMC, diagnostics, service processor, andread-only memory (ROM) resident code, locally or over the LANv Vital product data (VPD) on microprocessors, system boards, power supplies,and SAS (hot-swap-drive) backplanev Wake on LAN capability10 IBM System x3755 M3 Type 7164: Installation and User’s Guide
