NonStop (server computers)

NonStop is a series of <a href="/facts/Server_(computing)/dEaYFD7r">server computers</a> introduced to market in 1976 by <a href="/facts/Tandem_Computers/m8syzN1q">Tandem Computers</a> Inc., beginning with the NonStop <a href="/facts/Product_line/CXJV5fV9">product line</a>. It was followed by the Tandem Integrity NonStop line of <a href="/facts/Lockstep_(computing)/KbfWl3g4">lock-step</a> fault-tolerant computers, now defunct (not to be confused with the later and much different <a href="/facts/Hewlett-Packard/abuNSYNu">Hewlett-Packard</a> <a href="/facts/HPE_Integrity_Servers/uA4go4PG">Integrity</a> <a href="/facts/Product_line_extension/cFCRCMe2">product line extension</a>). The original NonStop product line is currently offered by <a href="/facts/Hewlett_Packard_Enterprise/d9NbClDt">Hewlett Packard Enterprise</a> since Hewlett-Packard Company's split in 2015. Because NonStop systems are based on an integrated hardware/software stack, Tandem and later HPE also developed the NonStop OS <a href="/facts/Operating_system/8XTuvMh2">operating system</a> for them.
NonStop systems are, to an extent, self-healing. To circumvent <a href="/facts/Single_point_of_failure/royNGgjd">single points of failure</a>, they are equipped with almost all <a href="/facts/Redundancy_(engineering)/odqzTmIo">redundant</a> components. When a mainline component fails, the system automatically falls back to the backup.
These systems can be used by <a href="/facts/Bank/l7VsKwas">banks</a>, <a href="/facts/Stock_exchange/lTJvjyVW">stock exchanges</a>, payment applications, retail companies, energy and utility services, healthcare organizations, manufacturers, telecommunication providers, transportation, and other enterprises requiring extremely high <a href="/facts/Uptime/7PXQlwEE">uptime</a>.
