Server Virtualization

What is Server Virtualization?

Server virtualization allows users to maximize physical resources in the most efficient way possible. Server virtualization functions by running multiple, independent, virtual operating systems on a single computer.

Server virtualization transforms hardware into software, creating a virtual hardware resource on an x86-based server that incorporates CPU, RAM and hard drives.

How Can I Help My Organization Embrace Server Virtualization Solutions?

When evaluating the implementation of a server virtualization solution, it's important to discuss:

• How much of your IT budget and staff is dedicated managing hardware, utilities, and real estate?
• How many physical servers are in your current environment, and how well are they utilized?
• How quickly and efficiently is your organization deploying new servers?

What Comprises a Server Virtualization Solution?

An effective server virtualization solution requires the following technology considerations:

Platform

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 virtualization software.

Server Hardware

While it's possible to use existing server hardware, most organizations upgrade to achieve increased processing speeds and memory capacity. Server hardware choices include: rack or blade; 2-way, high-end, or or 16 way servers or Intel or AMD based processors.

Shared Storage

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.

Network Hardware

Understanding your network environment is key as certain server virtualization features now require Gigabit connectivity. New technologies like Fiber Channel over Ethernet (FCoE) can reduce the number of Ethernet connections per server.

Licensing

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.

Support

In any server virtualization solution, multiple components will need to work together. Most server virtualization platforms require a support purchase with each software license.
