The always-on operating system

The HPE NonStop operating system (OS) is unique. It delivers fault tolerance through a share-nothing parallel processing architecture with multiple levels of error detection. Fault isolation and workload takeover capabilities provide application and database availability on both a local and global scale. As a result, HPE NonStop has unparalleled ability to detect, isolate, and recover from hardware and software failures without affecting critical applications and their users. The NonStop OS has been protecting mission-critical processes for over 40 years.

Run fault-tolerant NonStop solutions in the cloud

Now you can run mission-critical NonStop solutions in your private cloud and get the operational flexibility and agility offered by cloud technologies. HPE NonStop brings mission-critical availability to cloud-based applications and aligns with your enterprise cloud strategy. HPE Virtualized NonStop—deployed and managed through standard OpenStack services—can be built on your choice of infrastructure and deployed in your enterprise private cloud. You can run applications built for the HPE NonStop X systems, without any modification, in your private cloud.
