The Power of Green Power Server from IBM
IBM Hardware and software giant’s has unveiled the latest version of its Power processors, which will form a foundation for companies green IT efforts. This type of Green power processors helps into new revenue streams. IBM is keen to tap into users’ energy concerns while boosting revenue.
The Power7 uses a 45 nanometer process. Each Power7 processor has up to eight cores and four threads per core. That’s four times the maximum number of cores and eight times the number of threads per chip as the Power6.
The Power7 has a TurboCore mode, which is optimized for database and other transaction-oriented workloads. This runs with four cores active and with most of the resources from the other four cores behind the eight active cores. Doing this gives the four active cores more cache memory and memory bandwidth and increases their clock speeds.
Power7 technology has “intelligent threads,” meaning the number of threads varies depending on the workload. More threads increase total capacity, and fewer threads increase individual processing tasks, such as real-time analytics and database transactions.
Active Memory Expansion, a new Power7 technology, dynamically adjusts the amount of compressed memory required based on a workload’s needs. This expands the memory capacity of Power7 systems without requiring the installation of more physical memory. A server using Active Memory Expansion can handle up to 65 percent more transactions or users than servers without this feature, according the IBM’s estimates.
Intelligent Energy technology in the Power7s lets customers power on and off various parts of the system, or dynamically increase or decrease processor clock speeds based on thermal conditions and system utilization. They can do this on a single server or across a pool of multiple servers.
