Reliability, availability, and serviceability
Three of the most important features in server design are reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on your blade server; that your blade server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.
The following is a list of some of the RAS features that your BladeCenter unit supports:
vShared key components, such as power, cooling, and I/O
vAll components serviced from the front or rear of the chassis
vAutomatic error retry and recovery
vAutomatic restart after a power failure
