Xen, a new open source software resource, makes it possible to run multiple operating systems on a single computer.

More accurately called a ‘virtual machine monitor’, Xen allows you to leverage your existing hardware by properly utilising the processing capabilities of your PCs and servers without having to invest in additional hardware.

Xen offers a solution that provides excellent stability, performance, security and control over resource usage. Xen enables enterprises to cut costs through server consolidation. It's fast, lean and secure.

NSP is one of the world’s leading developers of servers that incorporate Xen functionality. “We’ve harnessed the power of Xen to create a redundant ‘Shadow Server,” says Larsen, “and the benefits are immense. Customers can run File Server, Mails Server or a Remote Access Server simultaneously on the same machine. Or they may wish to fully replicate their servers on a separate machine.

With Xen and NSP Shadow Server IT managers can migrate files to another machine without down time or impact on the users. With uptime a critical issue with many Internet-based companies, this type of stability and scalability is essential.

And Xen means that it is now more affordable than ever.”
