Security for virtualized datacentres

The Mitsubishi Electric Corporation said today it has developed synchronous SRAM which will work at 500MHz/ Further, the technology is 100 times more resistant to cosmic ray soft errors than previous chips. According to Mitsibushi, soft errors caused by cosmic rays have plagued the semiconductor business and caused problems for execs using notebooks when they're flying. The neutrons are 100 times more concentrated at 30,000 feet, said Mitsubishi. The 500MHz synchronous SRAM will be used with 800MHz processors throughout 1999 and into 2000 as second level cache, said Mitsubishi, so telling us something that Intel hasn't explained, yet. Personally, it isn't neutrons that plague us when we're flying -- it's usually lack of cigarettes, air rage and a battery life on our ThinkPads of precisely 20 minutes... ®
