Companies around the world have saved money by migrating from competitive UNIX servers and consolidating on IBM Power Systems. For instance, Energen, one of the top 20 independent oil and gas exploration and production companies in the United States, was able to save more than $500,000 annually by consolidating 20 Sun servers onto two System p 570 servers. The project accelerated new server deployment from one month to two days.

"The server consolidation project was hugely successful," said Brunson White, vice president and CIO of Energen. "We have never completed a project that has so quickly generated as much return on investment as this one. And we achieved increased system performance as well."

"Today's announcement of incredibly high-value UNIX and supercomputer solutions, coupled with last week's announcement of the first of a new generation of servers that takes our System i clients forward on a mainstream platform, opens up a whole new world of possibilities for our Power Systems clients," said Ross Mauri, general manager, IBM Power Systems. "The world's most powerful enterprise UNIX server with superior virtualization for workload balancing across UNIX, Linux and i applications and the water-cooled supercomputer represent major breakthroughs in innovation and energy efficiency for IBM clients and make the new enterprise data center a reality. Sun and HP UNIX customers just might discover the new Power Rewards program is the impetus to make the switch to the Power roadmap."

Leading UNIX Provider
According to IDC, IBM today ranks as the leading provider of UNIX solutions and has led for the last 10 quarters on a rolling four-quarter average of revenue. Last year, IBM gained revenue share again and maintained UNIX leadership with a 33.8 percent share and finished 3.1 points ahead of number 2 Sun and 7.7 points ahead of number 3 HP. In fact, IBM is the only major UNIX vendor to gain cumulative revenue share in the past five years (+11.3 points) while both Sun (-1.7 points) and HP (-4 points) lost share between 2003 and 2007.

IDC forecasts this market will continue to grow, with combined UNIX and Linux server spending to increase $1.2 billion between 2007 and 2011, to a total opportunity of $27.4 billion in 2011, 45 percent of all projected customer spend.

New Enterprise UNIX Server
The new 64-core, 128-thread Power 595 now ranks as the world's fastest UNIX system. Using the latest 5.0 GHz POWER6 processor chips with dual memory controllers, and leveraging a new, sophisticated symmetric multi-processor (SMP) point-to-point interconnect to communicate between its cores, the Power 595 bested the results of all competitors for running large two-tier environments running the SAP ERP application. In fact, two-tier SAP Sales and Distribution (SD) Standard Application Benchmark results showed a 32 processor/64-core/128 thread Power 595 can handle more than twice the number of users per core of a 64 processor/128-core/256 thread Itanium-based HP Superdome system.

The Power 595 SMP point-to-point interconnect starts with 8-core nodes that are built from four dual-core POWER6 chips tightly integrated into one module with direct interconnects between all four chips in the node. Then these 8-core nodes are connected into a superlinear-scaling fashion meaning each time a node is added it is connected point-to-point to all previous nodes, so that together there are actually 28 interconnects between those eight nodes. This provides massive amounts of bandwidth to gain the maximum exploitation of the total system processor, memory and cache capability.

The Power 595 supports up to 4 TB of memory per server, twice as much as the HP Superdome and Sun SPARC. Continuing the IBM tradition of innovation with the Power Architecture systems design, the Power 595 also supports four memory operations per cycle and an aggregate memory bandwidth of more than 1.3 TB/sec (terabytes per second), which is enough to transfer in each second the amount of information printed on the paper made from 50,000 trees.

With clients purchasing more and more servers, the advanced capabilities of the Power 595 are designed to help simplify the infrastructure and save enterprise data center costs through server consolidation, easier systems management and energy savings. For example, POWER6 EnergyScale technology, working in concert with IBM Systems Director Active Energy Manager, supports all Power Systems servers. It provides the capabilities for better facility planning, energy and cost savings, and peak energy usage control, and can increase energy efficiency for Power Systems users by up to 25 percent.

Virtualization for New Enterprise Data Center
Featuring up to 254 virtualized partitions, the Power 595 offers leadership virtualization technology for large-scale consolidation with optional PowerVM technology. IBM estimates more than 90 percent of Power Systems enterprise servers currently use PowerVM technology to more effectively manage their IT costs.

PowerVM Enterprise Edition offers Live Partition Mobility on the Power 595, allowing an entire AIX or Linux partition to be moved, while running, to another POWER6 processor-based system, allowing the reduction or elimination of planned downtime and increasing application availability. Live Partition Mobility is an exclusive of IBM POWER6 UNIX and Linux. HP and Sun do not have the same feature for their SPARC or Itanium technology-based systems.

Filling out the Power Systems lineup, IBM recently introduced the Power 520 Express and Power 550 Express -- i Editions for the SMB market. The new Power 570 is a unified version -- with common firmware, pricing, and a single set of feature codes -- combining the already in-market POWER6-based System p 570 and the System i 570.

The new Power 570 runs any permutation and combination of i, AIX or Linux partitions offering the ultimate in flexibility and increased asset utilization and reuse. And with PowerVM, Power servers also run many Linux x86 applications.
