IBM released three new members of its BladeCenter family today with a focus on energy efficiency features. For the first time, IBM is also offering an optional modular 4 GB USB drive that uses Flash storage as an alternative to a traditional hard disk.
The new offerings include the BladeCenter HS21 ($3,067 or $3,189, based on choice of 1.60 or 1.86 GHz 50 watt Intel Xeon quad-core LV processor); the BladeCenter LS21 and the LS41, which run on a 68 watt dual-core AMD Opteron processor.
estimates the solid state Flash drive consumes about five percent as much energy as a spinning hard disk with mechanical parts. The Flash drive is also much faster. The average spin-up and seek time for a conventional hard disk is around 15 milliseconds while IBM said a Flash device takes only 0.1 milliseconds.
Joe Clabby, president of Clabby Analytics, said IBM’s inclusion of Flash storage, even an option, is significant. “It means you get an immediate fast boot,” Clabby told internetnews.com. “Over time there is a promise that this will be a real efficient way to do blade systems.”
At 4GB, the Flash drive has only a fraction of the capacity of a standard hard disk, but still costs about the same. But IBM sees distinct advantages. “Mechanical drives have a much higher failure rate,” Doug Balog, vice president and business line executive for IBM BladeCenter, told internetnews.com.
He also said the extra storage that comes with standard hard disks is mirrored by other storage in the data center and not really needed. “The Flash drive is a great device for booting to environments like Linux,” said Balog.
Low voltage processors reduce energy use but are not at all unique to systems from IBM. Balog noted other technology component can also be designed for greater energy efficiency. He spoke by phone from a blade customer event this week where he said there are users with as few as six and as many as 6,000 blades. “About 75 percent of them see power and cooling as one of the top issues, regardless of the size of their company,” said Balog.
The new BladeCenters and System x servers IBM also just introduced include a feature called Calibrated Vectored Cooling, which manages air intake, fan placement and zone cooling technologies. The idea is to maximize the air flow inside the blade and rack server for optimal cooling efficiency. IBM also includes its PowerExecutive software designed to help customers meter, control and cap power consumption across systems.
