SWsoft says that a series of test have shown Virtuozzo 2.5 to be the most powerful server virtualization software for Intel Xeon processor-based servers, allowing up to 64GB of RAM and 16 CPUs per virtual environment. In stress testing on IBM and Dell hardware, Virtuozzo used the full potential of the Xeon-based servers, operating 2,500 virtual environments on a single server.

The Virtuozzo platform, says SWsoft is designed for use in enterprise server consolidation, software development systems, high-security and high-availability systems and as the backbone of the company?s HSPcomplete hosting automation solution.

"The Virtuozzo 2.5 technology running on Intel Xeon processor-based systems allows SWsoft?s customers to cost effectively host and manage large networked environments," says Melissa Laird, director of Intel Developer Services. "We are pleased that SWsoft participated in Intel?s Early Access Program to optimize their Virtuozzo software."

SWsoft says Virtuozzo is used by hosting providers to power virtual private server hosting plans, which provide an increase on revenue per customer and per server. New features of the 2.5 release include improved VE migration between servers; OS template support for Linux and FreeBSD; and an open XML-based API.
