DYNIX/ptx is an operating system first developed by Sequent Computer Systems to run on their x86 SMP (symmetric multiprocessor) servers. Sequent Computer Systems was later acquired by IBM who made an enhanced enterprise class operating system for NUMACenter and NUMAQ series designed for the Intel environment.
DYNIX/ptx is designed for commercial DBMS environments requiring scalability, performance, high availability, and manageability. Many of the largest open systems relational database applications in the world today run DYNIX/ptx operating system. A data center operating DYNIX/ptx is ideal for demanding mission-critical business applications requiring high throughput, quick response times, and 24/7 availability.
