DYNIX/ptx is an operating system first developed by Sequent Computer Systems to run on their x86 symmetric multiprocessor (SMP) 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 and its software products are designed for high-end commercial database management system (DBMS) environments requiring scalability, performance, high availability, and manageability. The largest open systems relational database applications in the world today—supporting thousands of users and many terabytes of data—are running DYNIX/ptx. A data center operating DYNIX/ptx is ideal for demanding mission-critical business applications that require very high throughput, quick response times, and 7x24 availability.
