The , IBM's top-selling midrange server, is now available with a 5GHz Power6 processor, which was previously available only in IBM's high-end system. The manufacturing yields for the 5GHz chip have been good enough that IBM can offer it in higher-volume systems, said Scott Handy, IBM vice president of worldwide marketing and strategy.
IBM also doubled the maximum density for the Power 570, so customers can put up to eight 4.2GHz processors in each server node, or up to four 5GHz processors. The nodes can be stacked four high for a total of 32 4.2GHz processors in a single box.
The enhancements boost the performance customers can get from each square foot of server space and from each watt of power, making the 570 well-suited for virtualization and consolidation, Handy said.
IBM is also testing a new capability for its virtualization software that allows administrators to share virtual system memory between partitions, in the same way they can share virtual processors today. Called Active Memory Sharing, the technology is in closed beta and due for general availability in the first half of next year.
Also planned is a new version of that lets administrators cap the energy being used by a pool of servers. Due later this quarter, the software will throttle down processor and fan speeds if an application tries to exceed a certain power threshold. The software will be a plug-in for . The portion for monitoring power use is free, but the tool for throttling down consumption will cost about US$275 per server for the Power 570, an IBM spokesman said.
IBM hopes the improvements will help keep it on top of the Unix server market. IBM regained its lead in Unix server revenue in the second quarter, growing its share 5 percentage points from a year earlier, according to IDC. Sun Microsystems, in second place, dropped 5.6 percent percentage points over the same period, while third-place Hewlett-Packard gained 1 point, IDC said.
"Ever since their resurgence in the Unix market, IBM has been pushing performance up and prices down when they really don't have to," said Dan Olds, principal analyst at in Beaverton, Oregon. "Right now they have the performance lead, and they are still pushing the speeds and feeds higher. They're keeping constant pressure on Sun and HP."
Among the other IBM Unix news Tuesday:
-- A new technology for ensuring high availability for applications, called hot node and repair, will be available later in the quarter for the Power 570 and 595 systems. If a server indicates it is about to fail, the software allows an administrator to shift a workload to a different server while the first server is repaired, and then move back again without losing transactions, according to IBM.
-- IBM doubled the processor cores available in its System i servers, which run its i OS, to bring them on par with its AIX and Linux offerings. The System i 550, for example, now comes with up to eight processor cores, up from four. IBM said the move completes an effort to offer a common hardware platform for its servers running Linux, AIX or i5/OS.
-- A new server for mid-size companies, the Power 560 Express, is due on Nov. 21. It uses a 3.6Ghz Power6 processor, comes in four-, eight- and 16-node configurations, and packs a hefty 384G bytes of memory. It's designed for companies looking to run multiple applications on a virtualized system. It will be offered with Linux, AIX or i. Pricing wasn't announced.
--IBM said its blade server can now be pre-installed with its i software and attached to its DS3200 storage gear to create a low-cost SAN (storage area network).
-- Handy said almost two-thirds of IBM's Unix servers shipped in the second quarter included its PowerVM virtualization software, up from 21 percent in the second quarter the year before.
