Boasts an improved OS virtualization technology that solves the common performance, density, usability and infrastructure compatibility issues.

SWsoft, a server virtualization and automation software provider, yesterday unveiled the beta version of Virtuozzo 4.0, the company's operating system virtualization software for data centers. The company will be demonstrating Virtuozzo 4.0 this week at VMworld in booth 1312 at the Moscone Convention Center in San Francisco.

The company claims that the Virtuozzo 4.0's improved OS virtualization technology solves many of the common performance, density, usability and infrastructure compatibility issues that plague traditional hardware virtualization solutions via a number of improvements and new features, including:

Enhanced Usability – A redesigned interface that offers access to centralized resources, such as easy-to-use application templates and sample containers, plus streamlined installation;

High Availability – Virtuozzo 4.0 includes several new options to drive uptime, such as Red Hat and Windows Server 2003 clustering services, as well as real-time backups across Linux and Windows platforms;

Complete Management Flexibility – Arrange and manage virtual containers and Virtuozzo servers according to either the actual hardware infrastructure, or logically group them according to user preference.

"We've used Virtuozzo since February 2006 to offer high-performance VPS solutions to thousands of customers, with only a minimal increase in real server resources. We're looking forward to implementing Virtuozzo version 4 and making use of its new features to provide our customers with an even higher level of service," said Andreas Gauger, chairman of 1&1 Internet.

"Virtuozzo 4.0 is a major step forward in our mission to provide customers with a solution that addresses multiple key barriers to service provider profitability, namely revenue per square foot, manageability and uptime. Integration with our complete line of automation, billing, and management solutions through our OPEN FUSION initiative makes Virtuozzo the most complete solution for service providers," said Serguei Beloussov, CEO of SWsoft.

Virtuozzo 4.0 will be available for public beta testing by the end of September, with general availability expected later this year. Current versions of Virtuozzo are available worldwide from SWsoft or any of its partners.
