IBM shares results of its Power7 benchmarks which incorporate the energy efficiency perspective.  …

…   “IBM has achieved the industry’s highest ever TPC-C (transaction processing) benchmark using a Power Systems configuration with DB2, hitting 10,366,254 transactions per minute, which beat HP’s best result by more than 2.5 times and Oracle’s best by more than 35%.

The IBM result represents 2.7 times better performance per core than the Oracle result, 41% better price performance, and 35% better energy efficiency per transaction.

HP’s best result is over twice as expensive per transaction as the IBM result. “   …

SeaMicro low power server technology built on Atom processors

Posted in atom-cpu, datacenter-server, low-power, microprocessors, reduce-power-consumption, seamicro, servers on June 14th, 2010 by FrankM – Comments Off

SeaMicro has commercialized a low-power Internet-optimized x86-server that reduces energy consumption and space by 75 percent. The company’s SM10000 servers are setting the bar for internet workloads. The server integrates 512 Intel Atom processors with Ethernet switching, server management and application load-balancing. The server consumes one-quarter of the power and takes one-quarter of the space to match the best-in-class internet server. …

…   “Beyond the fundamental mismatch between today’s servers and the dominant workload, SeaMicro made another critical observation that set the stage for massive reductions in server power.

The CPU, usually the focus of power reduction efforts, consumes only one third of the power in a server.

This means that large improvements in the CPU have only modest impact on the total power consumed by a server. In order to achieve large-scale power reductions, SeaMicro technology focused on the two-thirds power consumed by the non-CPU components.

To this end, SeaMicro transformed the volume server into a high density, low power, single-box cluster computer, optimized for Internet traffic.

SeaMicro further improved total cost of ownership and reduced the power consumed in a data center solution by integrating the functionality traditionally found in an entire data center rack – compute, storage, networking, server management and load balancing – into a single, low-power system.

Building on the dramatic reductions in power achieved at the system level, SeaMicro was then able to leverage low power CPUs, such as Intel’s Atom processor. “   …

Juniper Networks creates data center network architecture to flatten legacy data center networks from three to two layers preparing the enterprise for future network fabric. …

… “Juniper’s 3-2-1 architecture helps customers simplify data center networks while simultaneously improving the economics and experience of IT and end users. Customers can now eliminate an entire layer of switching from their networks, delivering lower latency and higher performance, smaller footprint and lower power consumption, simplified management and lower total cost of ownership. By applying Juniper’s Virtual Chassis fabric technology to the access layer, Juniper eliminates the need for aggregation — a primary source of complexity in the data center network — and can reduce the number of switch interactions by up to 99 percent compared to legacy three-layer networks. It also improves application performance by reducing latency up to 77 percent compared to legacy three-layer networks. ” …
