977 words - 4 pages

You are a Windows 7 administrator at Contoso, a very large and international pharmaceutical company. You have 25 servers in your network running a combination of Windows Server 2000, Server 2003, SuSe Linux. As your Chief Information Officer is brainstorming with you and his/her staff, you mention that you have heard about Virtualization and it may be a very cost effective and efficient way to upgrade everything to Windows Server 2008. Your boss tells you to research the concepts and to get back to him in two weeks with a recommendation.
My solution is to use server virtualization, which would allow multiple servers to be installed on one or more existing servers. This saves floor space and money since you don’t have to purchase new servers or expand the square footage of your server room.
How Virtualization Works
Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. You probably know a little about virtualization if you have ever divided your hard drive into different partitions. A partition is the logical division of a hard disk drive to create, in effect, two separate hard drives. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. The technology got its start on mainframes decades ago, allowing administrators to avoid wasting expensive processing power. (Search server virtualization, 2013)

The other forms of Virtualization
Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. The idea is that virtualization disguises the true complexity of the network by separating it into manageable parts, much like your partitioned hard drive makes it easier to manage your files. Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization is commonly used in storage area networks (SANs). Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later. (Search server virtualization, 2013)
