Reliability, availability and serviceability

<p>Reliability, availability and serviceability (RAS), also known as reliability, availability, and maintainability (RAM), is a <a href="/facts/Computer_hardware/8jSjsCNv">computer hardware</a> engineering term involving <a href="/facts/Reliability_engineering/cd6AS5w3">reliability engineering</a>, <a href="/facts/High_availability/y3J8GnEo">high availability</a>, and <a href="/facts/Serviceability_(computer)/w9nQfmJF">serviceability</a> design. The phrase was originally used by <a href="/facts/IBM/QszA7nwd">IBM</a> as a term to describe the robustness of their <a href="/facts/Mainframe_computer/nrBR6rWa">mainframe computers</a>.
</p><p>Computers designed with higher levels of RAS have many features that protect <a href="/facts/Data_integrity/g3XGbKIH">data integrity</a> and help them stay <a href="/facts/Availability/l8SGSyyf">available</a> for long periods of time without <a href="/facts/Fault_(technology)/jeQPed50">failure</a>. This data integrity and  <a href="/facts/Uptime/7PXQlwEE">uptime</a> is a particular selling point for mainframes and <a href="/facts/Fault-tolerant_system/rasrYlJk">fault-tolerant systems</a>.
