The IBM Power® 795 server is designed for enterprises to support large-scale transaction processing and database applications within a highly virtualized system infrastructure, enabling new levels of workload consolidation, resource utilization and efficiency. As the most powerful member of the IBM Power Systems™ family, this server provides exceptional performance, massive scalability and bandwidth to efficiently and concurrently support a full range of complex, mission-critical applications.
Equipped with up to 256 POWER7® processors the Power 795 server can scale rapidly and seamlessly to address the changing needs of today’s business climate. Equipped with industry-leading PowerVM™ virtualization, EnergyScale™ technology and affordable Capacity on Demand (CoD) options, the Power 795 helps enterprises increase their productivity and effectively consolidate multiple UNIX, IBM i and Linux® workloads onto a single system.
Extensive mainframe-inspired reliability, availability and serviceability (RAS) features in the Power 795 help ensure that mission-critical applications run reliably around the clock. IBM clients with installed Power 595 systems may leverage their current investment in Power technology by upgrading their POWER6® system to a Power 795 to increase capacity and improve performance.
With extensive scalability, a fundamentally reliable design and expansive growth potential, the Power 795 server provides a solid foundation on which to deploy the most important applications in today’s large enterprise data centers.
