NYSE places buy on Linux, hold on Unix

The New York Stock Exchange is investing heavily in x86-based Linux systems and blade servers as it builds out the NYSE Hybrid Market trading system that it launched last year. Flexibility and lower cost are among the goals. But one of the things that NYSE Euronext CIO Steve Rubinow says he most wants from the new computing architecture is technology independence.

"What we want is to be able to take advantage of technology advances when they happen," Rubinow said. "We're trying to be as independent of any technologies as we can be."

The Hybrid Market system lets NYSE traders buy and sell stocks electronically or on the exchange's trading floor. The NYSE has been turning to x86 technology to power the trading system, largely using servers from Hewlett-Packard Co., the two companies announced this week.
