VMWare has brought out the big guns this time with the release of VMware Infrastructure 3. This product is the ultimate product for companies who are looking to test their software, hardware, or any device on other systems by using virtualization. This is the description that VMware gives:
VMware Infrastructure 3 is the next generation of industry-leading infrastructure virtualization software that virtualizes servers, storage and networking, allowing multiple unmodified operating systems and their applications to run independently in virtual machines while sharing physical resources. The suite delivers comprehensive virtualization, management, resource optimization, application availability and operational automation capabilities.
The cheapest packages will cost you $1000 while the most expensive will be about $5,750. They are working on support for 64-bit operating systems but it works well with most Microsoft, Linux, and Solaris x86 operating systems.
