Virtualisation firms get ready for a real battle
Published: 06 Feb 2006 09:05 GMT
Three companies selling virtualisation software will try to advance their respective fortunes on Monday with new software, a new partnership and a new promotion.
All three companies — Virtual Iron, SWsoft and VMware — sell software designed to let computers run more efficiently by providing applications a virtual foundation instead of the real one the applications think they're using. That virtual foundation means that a single server can run more jobs at the same time and that the jobs can more easily be moved from one computer to another.
As expected, market leader VMware will make its GSX Server software free — and change its name to VMware Server. The move is intended to show the company's software maturity and advantages and let many more potential customers try it out, Diane Greene, VMware's chief executive, said.
"When you have something that's free out there, people try it a lot faster," Greene said. "Once [they] use it, they say, 'This is really good stuff,' and they want to standardise on it."
VMware still charges for its higher-end ESX server product, which is responsible for the bulk of the company's revenue growth. ESX is often sold in conjunction with the company's management tools in a package called the Virtual Infrastructure Node.
A basic advantage of virtualisation is the ability to run multiple jobs gracefully on a single server, a consolidation that cuts administrative expense and electricity bills. At a higher level, it permits computer systems to become more responsive to changing work priorities or hardware problems.
VMware pioneered the technology for running multiple virtual machines, each with its own operating system, on a single computer. But the days when the EMC subsidiary had the market to itself are over. VMware Server is similar to Microsoft's Virtual Server; open source Xen, while relatively immature and not available for Windows, reproduces the basic features of ESX server.
A New York conference, IDC's Virtualisation Forum, is providing a good reason for other rivals to try to win some attention.
Among them are start-up Virtual Iron, a company whose software is designed not only to run multiple operating systems on one machine but also to let a single operating system span several machines. The company hopes its approach will lead to easily reconfigurable computing systems that fluidly respond to changing work demands. The technology has been used in mainframes for decades, but now is making its way to mainstream servers as well.
Virtual Iron's approach uses a technology called paravirtualisation that requires changes in the operating system. The company plans to announce that Novell, the number two Linux seller, now provides that support in a version of its SuSE Linux Enterprise Server product.
In addition, Virtual Iron won an endorsement from IBM, which said the software is a good fit for its BladeCentre servers.
However, Virtual Iron is still getting started. The company has six customers, a representative said, declining to reveal any names but saying they are in the industries of financial services, aerospace, distribution and Web hosting.
Another company that already has several customers in the Web hosting business is SWsoft, which sells a product called Virtuozzo that subdivides a single copy of the operating system so different applications believe they have a whole computer to themselves. Each of these partitions is called a virtual private server.
SWsoft released version 3.0 of its Linux product, which adds a feature called Zero Downtime Migration that lets a virtual private server be moved from one computer to another without shutting it down. Virtuozzo costs $1,000 per processor.
Version 3 also adds support for Red Hat Enterprise Linux 4.0. In addition, the company released version 3.5.1 of Virtuozzo for Windows, which is faster than predecessors and includes a feature that lets conventional server software be moved to the virtual private server foundation.
