Reliability, Availability, And Serviceability Features - IBM eServer 370 xSeries User Reference Manual

Reliability, availability, and serviceability features

Three of the most important factors in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored
on your server; that your server is available when you want to use it; and that
should a failure occur, it can be easily diagnosed and repaired with minimal
inconvenience.
The following is an abbreviated list of the RAS features on the IBM xSeries 370
server. Many of these features are explained in the following chapters of this book.
