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 the server, the availability of the server when you need it, and the ease
with which you can diagnose and repair problems.
The server has the following RAS features:
v Automatic error retry and recovery
v Automatic restart after a power failure
v Backup basic input/output system (BIOS) switching under the control of the
v Baseboard management controller (service processor)
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Cable-presence detection on most connectors
v Chipkill memory protection
v Error codes and messages
v Error correcting code (ECC) L2 cache and system memory
v Fully-buffered DIMMs (FBD) support
v Hot-swap cooling fans with speed-sensing capability
v Hot-swap hard disk drives
v Hot-spare memory
v Information and light path diagnostics LED panels
v Memory mirroring
v Menu-driven setup, system configuration, and redundant array of independent
v Parity checking or CRC checking on the serially-attached SCSI (SAS) bus and
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 Redundant power supplies and redundant hot-swap fans (ac power supplies are
v Remind button to temporarily turn off the system-error LED
v Remote system problem-determination support
v Standby voltage for systems-management features and monitoring
The server supports an optional IBM Remote Supervisor Adapter II SlimLine.
When you use this adapter, you can manage the functions of the server locally
and remotely. The Remote Supervisor Adapter II SlimLine also provides system
monitoring, event recording, and dial-out alert capability.
The Ethernet controllers in the server support TOE, which is a technology that
offloads the TCP/IP flow from the microprocessors 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.
