In an effort to be ahead of the competition in the demanding and rapidly changing hardware market, IBM introduces its news server systems that can run power grids or process financial analytics – the Power7 server systems.
Power7 is comprised of integrated servers, software and storage and can be tailored depending on an enterprise’s requirements. Clients can choose between high-end Power 780 with TurboCore mode, Power 770 – a midrange server with up to 64 cores, the high-performance cluster Power 755 with 32 cores and the midmarket Power 750 Express.
The Power7 servers deliver twice the performance and four times the virtualization capabilities for the same price as the Power6 servers, all the while consuming half the energy, according to IBM.
Power 780′s TurboCore mode is a workload optimization feature that can have four cores running, and put the resources—including cache memory and memory bandwidth—of the other four dormant cores before those active ones. It also can increase the clock speed of those four active cores.
All Power7 systems supports MaxCore mode, which takes advantage of its increase in thread count. Other features of Power7 series include Intelligent Threads chips, a technology that can dynamically change the number of threads being run depending on the type of workloads.
Another feature is Active Memory Expansion, which utilizes memory compression technology to make the physical memory appear to be twice as large as it actually is, and can dynamically change the amount of compressed memory based on workload demands.
