Reliability, availability, and serviceability features
Three important features in server design are reliability, availability, and
serviceability (RAS). These RAS features are designed to help you protect the
integrity of the data stored on your blade server; help ensure that your blade server
is available when you want to use it; and, in the event of a failure, help you easily
diagnose and repair the failure with minimal inconvenience.
The following is a list of some of the RAS features that your blade server supports:
v Automatic error retry or recovery
v Automatic server restart
v Built-in monitoring for temperature, voltage, and hard disk drives
v Customer-upgradeable system firmware code
v Diagnostic support of Ethernet controller ports
v Error codes and messages
v Error correcting code (ECC) protection on the Level 2 (L2) cache
v ECC memory
v Service processor that communicates with the BladeCenter Management Module
v SDRAM with serial presence detect (SPD) and vital product data (VPD)
v System error logging
v VPD (includes information stored in nonvolatile memory for easier remote
