Doing battle in the US$9 billion Unix server market is not for the timid. Designing a competitive microprocessor is a costly business, and with the Unix market seemingly in permanent decline it's easy to see why smaller players might drop out.
But Fujitsu says it's in it for the long haul. Despite its small market share, the company is committed to developing its Sparc64 chip, and it thinks it has a role to play in keeping IBM from becoming too powerful, said Noriyuki Toyoki, Fujitsu corporate senior vice president and the head of its server division.
IBM already has one giant "cash cow" from its dominance in mainframes, he said. If IBM came to dominate Unix in the same way — it already has more than half the market, according to IDC — the industry and its customers would be worse off, according to Toyoki.
"Two cash cows would make IBM much, much stronger. We have to stop it. That would not be good for us and it's never good for the customer. Customers need alternatives to get the best value," he said in an interview this week at Oracle OpenWorld.
Fujitsu is a close partner of Oracle. They each develop a version of the Sparc processor, and they jointly design systems and resell each other's products.
Oracle has been finding a wider role for its own Sparc designs lately, but Toyoki said the future of Fujitsu's Sparc64 is secure. The Unix market may be shrinking, but it's still large enough to support multiple RISC architectures, he said.
He brushed off a suggestion that Fujitsu could walk away from Sparc64 and use Oracle's chips instead. "Frankly, we would not use Oracle's Sparc chips in our servers," Toyoki said.
Oracle's chips perform well, he said — "they're very efficient, especially for throughput operations" — but Fujitsu's customers need the RAS (reliability, availability and serviceability) capabilities that bleed into Sparc64 from its mainframe systems.
Sparc64 is also important for Japan. A version is used in the country's massive K supercomputer, and Fujitsu is "the last Japanese company doing processor development. We'd like to keep doing it," Toyoki said.
Fujitsu released its new M10 Unix servers earlier this year, with its latest Sparc64 X processor. An upgrade to that chip, Sparc64 X Plus, should be available to customers in the first half of next year, Toyoki said.
It's a similar design to the Sparc64 X but boosts the clockspeed to a maximum 3.5GHz and adds on-chip accelerators to make tasks like encryption run faster. It also adds a Fujitsu technology called Coherent Memory Interconnect, or CMI, which Toyoki said will drastically reduce latency times for scale-out clusters.
