The servers are optimized for processing huge workloads of simultaneous transactions, data handling, and analysis. IBM said they offer "dramatic improvements" in price versus performance, energy savings, and server virtualization .

Energy Efficiency

The new systems are built around the newest generation of IBM's POWER chip, with eight processing cores, and are designed to manage millions of transactions in real time while utilizing a variety of approaches to remain highly energy-efficient. With Intelligent Energy technology, for instance, parts of the system can be turned on or off, and clock speed can be lowered or raised, on one server or a group. The company said these systems can deliver twice the performance per watt as Sun SPARC servers and eight times that of comparable Hewlett-Packard Itanium-based servers.

POWER7 systems are optimized for massive parallel processing, high-end throughput, and analytics, and the systems can be used to manage others, such as IBM mainframes and x86-based servers.

Laura DiDio, a research fellow at Information Technology Intelligence Corp., said these "turbocharged systems should really jumpstart multi-threading computing." She added that each of the eight cores can execute up to four tasks each, so "it's as if this were a virtual 32-core processor on a chip."

This capacity is four times the maximum number of cores in POWER6 systems and eight times the processing threads.

Smart Energy Grids

DiDio noted that these systems will enable a huge performance boost in the growing market of smart energy grids, allowing utility companies to go from a million meter reads a day to 85 million. In its announcement, IBM noted that "a major U.S. utility" will be using its systems to process that amount of information and present it to about five million customers in real time, instead of the traditional overnight batch processing.

There are four new systems. The Power 780 is a new category of scalable servers that offer a modular design and up to twice the performance per core of POWER6 processor-based systems.

The Power 770 is also modular and uses as much as 70 percent less energy per core as the previous Power 570. A high-performance computing cluster node called the Power 755 is Energy Star-qualified and designed for particularly challenging analytical tasks. And the Power 750 Express, with quadruple the processing capacity of the previous Power 550 Express, is also targeted at mid-market clients.

New management capabilities are offered through the updated Director Express management software, in both standard and enterprise editions.
