IBM, Mercury team up on Cell-based blade server

IDG News Service - IBM and Mercury Computer Systems Inc. plan to ship a blade server using the multicore Cell processor designed exclusively for IBM's BladeCenter rack system, the companies announced Thursday.

Starting in the first quarter of 2006, Mercury's customers will be able to purchase the dual-cell-based Blade, said Craig Lund, Mercury's chief technology officer. The two-chip blade server will be the first product available using the Cell processor, and it's designed as a development platform for Mercury's customers that are interested in using the chip for industrial and medical applications, he said.

Cell was the result of a three-way collaboration between IBM, Sony Corp. and Toshiba Corp. It has nine separate processor cores, including one PowerPC core and eight smaller processing units called synergistic processing elements (SPE). Sony's PlayStation 3 will be the first mass-market product to use the processor starting next year, but Mercury and IBM will bring it out first in their upcoming blade server, Lund said.

Detailed specifications will be shared with early customers under a nondisclosure agreement, Mercury said in a press release. The systems will use Rambus Inc.'s extreme data rate (XDR) memory and come with two Cell processors, the company said. Presentations at the Hot Chips show in August indicated that Cell will probably debut at a clock speed of 3.2 GHz

The unique combination of Cell's multiple cores requires software that must be tweaked to fully exploit Cell's capabilities. As a result, Mercury and IBM believe that many initial customers will purchase a single dual-cell-based blade server to use as a development workstation, Lund said.

Mercury builds motherboards designed for applications that need more performance or capabilities than are available in standard servers from companies such as IBM or Dell Inc. In many cases, those boards are combined into multiprocessor systems that resemble the Cell processor on a much larger scale. This means that applications for Mercury's existing products had to be written with multiple processing units in mind, Lund said.

As a result, Mercury and its customers have already developed several software and tools that Mercury believes will help its customers get started developing applications for Cell, Lund said. It's also working with several independent software vendors to get third-party applications ready for the Cell servers, but most applications used in the medical, industrial and military markets targeted by Mercury are developed internally, he said.

The server will run a version of Linux tweaked by IBM's programmers for Cell's multiple processing engines, said Satish Gupta, general manager of IBM engineering and technology services. IBM
