Sun has upgraded one of its most popular freeware products after releasing a major new version of its open source virtualization tool xVM VirtualBox, which includes the ability to cope with demanding server workloads.
VirtualBox proved popular when it first appeared back in 2007 from Stuttgart, Germany-based Innotek. Sun later acquired Innotek in February 2008. At the time, Sun revealed that the product had been downloaded over 4 million times, but Sun now says it has surpassed 14.5 million downloads and 4 million registrations worldwide, as well as more than 25,000 downloads a day.

So what is VirtualBox? Well, it is a x86 virtualization product designed for both enterprise and home use. Essentially it is both a desktop and server-virtualization hypervisor, and is freely available as open source software under the terms of the GNU General Public License (GPL).
It runs on Windows, Linux, Macintosh, and OpenSolaris hosts, and supports a large number of guest operating systems including Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD.
Put simply, if a user downloaded and installed VirtualBox onto their laptop, they could then run most any other popular operating system on the same machine besides its native OS. Or they could run several operating systems at the same time, depending on what hardware resources are available.
This makes it an incredibly useful tool for software developers who want to target multiple operating systems in order to maximize their audience and return on investment (ROI). VirtualBox gives them the opportunity to run things such test environments etc, on a single laptop for example.
Back in September last year, Sun said it had improved VirtualBox's performance and platform support when it released VirtualBox 2.0. But now the company has released a major upgrade, version 3.0, which it says offers improved desktop and server virtualization features.
On the desktop side, it can now run Microsoft Direct3D support for Windows guests, which allows for graphically intensive Windows applications, such computer modelling, 3D design, and games software, to run in a virtual environment. Support for version 2.0 of the Open Graphics Library (OpenGL) standard has also been added, which allows for high-performance graphical applications that typically use graphical hardware acceleration. Finally, support for a wider range of USB devices, such as iPods, mobile phones, and storage devices, has also been added.
But it is on the server side, which has seen the most significant updates. With more and more multithreaded database and Web applications making use of multiple CPUs, VirtualBox 3.0 can now support virtual SMP systems with up to 32 virtual CPUs (vCPUs) in a single virtual machine. This now gives VirtualBox the ability to run "heavyweight data-processing workloads."

Server virtualization is a popular option for dealing with mounting datacenter costs. Another equally promising approach is the use of an Application Delivery Controller. Citrix NetScaler provides a low-cost way for organizations to reduce their server count and accrue cost savings from a reduction in space, cooling, power and personnel.
