A thin virtualization layer partitions the physical server so you can run multiple servers simultaneously on a single server. The computing resources of the physical server are pooled and used by the virtual servers in a controlled manner. The virtual servers are isolated from the other virtual servers on the systems leaving them unaffected by the actions of the other virtual servers.

When considering server virtualization, it's important to ask the following questions:
What Comprises a Server Virtualization Solution?
An effective server virtualization solution utilizes multiple components:
The most popular server virtualization platform, Hypervisor, runs without the use of any general-purpose operating system. An alternative platform known as hosted virtualization requires an operating system underneath the server virtualization software.
While it's possible to use existing server hardware, most companies upgrade to achieve increased processing speeds and memory capacity. Server hardware choices include: rack or blade; 2-way, high-end, or 16-way servers or Intel or AMD based processors.
To gain maximum functionality of your virtualization environment, shared storage must be deployed. Storage protocols include fibre channel, iSCSI and NFS. Drive options include SATA and SAS drives as well as interconnect technology which includes SAS and fibre channel.
Understanding your network environment is key as certain server virtualization features now require Gigabit connectivity. New technologies, such as Fiber Channel over Ethernet (FCoE), can reduce the number of Ethernet connections per server.
Software licensing is often the most misunderstood component of a server virtualization deployment. Every platform licenses software and each operating system has its own licensing rules. Working with a knowledgeable licensing specialist will help you ensure compliance.
In any server virtualization solution, multiple components will need to work together. Most server virtualization platforms require a support purchase with each software license.
