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.
Your server has the following RAS features:
v Automatic error retry and recovery
v Automatic restart after a power failure
v Baseboard management controller (BMC) service processor
v Backup basic input/output system (BIOS) switching under the control of the BMC
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Cable-presence detection on most connectors
v Chipkill
v Error codes and messages
v Error correcting code (ECC) L2 cache and system memory
v Hot-swap hard disk drives, some drives
v Information and light path diagnostics LED panels
v Menu-driven setup, system configuration, and redundant array of independent
v Availability of microcode and diagnostic levels
v Parity checking on the small computer system interface (SCSI) bus and PCI
v Power management: Compliance with Advanced Configuration and Power
v Power-on self-test (POST)
v Predictive Failure Analysis
v Redundant Ethernet capabilities with failover support
v Hot-swap cooling fans with speed-sensing capability
v Redundant hot-swap power supplies and redundant hot-swap fans (some
v Remind button to temporarily turn off the system-error LED
v Remote system problem-determination support
v Standby voltage for system-management features and monitoring
v Startup (boot) from LAN through remote initial program load (RIPL) or dynamic
v System auto-configuring from the configuration menu
v System-error logging (POST and BMC)
v System-management monitoring through the Iner IC protocol
v Upgradeable POST, BIOS, diagnostics, BMC firmware, and read-only memory

embedded BMC. The Remote Supervisor Adapter II SlimLine, provides a
dedicated Ethernet connection at the rear of the server.
The Ethernet controllers in the server support TOE, which is a technology that
offloads the TCP/IP flow from the microprocessor and I/O subsystem to increase
the speed of the TCP/IP flow. When an operating system that supports TOE is
running on the server and TOE is enabled, the server supports TOE operation.
See the operating-system documentation for information about enabling TOE.
Note: As of the date of this document, the Linux operating system does not
support TOE.
