Installs Sun Fire T2000 servers adding capacity and performance for Concentric web hosting customers, while reducing power consumption.

XO Communications, a provider of web hosting services, today announced that it has significantly expanded the web hosting capacity and total processing power of its Concentric Clustered web hosting services platform.

XO has deployed new servers from Sun Microsystems that lower data center power consumption while providing Concentric customers with a 100 percent increase in processing resources to support their web hosting plans.

The new Sun Fire T2000 servers featuring the UltraSPARC T1 processor with CoolThreads technology, deliver breakthrough performance with space and power efficiency. The UltraSparc T1 processor has eight cores, each with four independent threads, providing a total of 32 processing elements per processor. With the new server deployment, the pool of processing capacity is larger, giving Concentric web hosting customers increased capacity and computing power, claims the company.

"Because all of our applications are naturally distributed across our server farm, Concentric's Web Hosting technology is well suited to maximize the benefits of Sun's CoolThreads technology," said David Schairer, Vice President and CTO of XO's Hosting Business.
