The HPE NonStop OS (operating system) provides the fault-tolerant software foundation for HPE Integrity NonStop and HPE Integrity NonStop X servers. The NonStop OS delivers fault tolerance through multiple levels of error detection, fault isolation, and workload takeover capabilities for application and database survivability on both a local and global scale. As a result, HPE NonStop servers can detect, isolate, and recover from hardware and software failures without affecting critical applications and their users.
The proven reliability and virtually unlimited scalability of HPE NonStop servers are enabled by the HPE NonStop OS, which combines the scalability of shared-nothing, massively-parallel processing architecture of NonStop servers with industry-leading application availability and uncompromising data integrity. POSIX compliant NonStop OS provides industry-standard application programming interfaces (APIs) and services. Tight integration between the HPE NonStop OS and the HPE NonStop SQL database enables absolute control over concurrent mixed-workload environments.
