+ bool "Reliability, Availability and Serviceability (RAS) features"
+ help
+ Reliability, availability and serviceability (RAS) is a computer
+ hardware engineering term. Computers designed with higher levels
+ of RAS have a multitude of features that protect data integrity
+ and help them stay available for long periods of time without
+ failure.
+
+ Reliability can be defined as the probability that the system will
+ produce correct outputs up to some given time. Reliability is
+ enhanced by features that help to avoid, detect and repair hardware
+ faults.
+
+ Availability is the probability a system is operational at a given
+ time, i.e. the amount of time a device is actually operating as the
+ percentage of total time it should be operating.
+
+ Serviceability or maintainability is the simplicity and speed with
+ which a system can be repaired or maintained; if the time to repair
+ a failed system increases, then availability will decrease.
+
+ Note that Reliability and Availability are distinct concepts:
+ Reliability is a measure of the ability of a system to function
+ correctly, including avoiding data corruption, whereas Availability
+ measures how often it is available for use, even though it may not
+ be functioning correctly. For example, a server may run forever and
+ so have ideal availability, but may be unreliable, with frequent
+ data corruption.
