What

server virtualization Mean?

Server virtualization, the use of technology is to separate software, including the operating system, makes use of the hardware. This means that you can run multiple environments on the same physical server. In some systems, this may mean that several identical operating systems running on the same computer. Other shops may decide to hold a Windows platform running a Linux system and a UNIX environment on a single server.

benefits of server virtualization

offers in today’s challenging business environment, server virtualization, many different benefits. Not only is the virtualization of servers and allow data to be mobile than ever, but also provides a cost effective way to offset flat or declining budgets. The following list contains the most important benefits:

Consolidation – Most large servers run applications that only a small percentage of their computing power. Also, software packages usually employs only a small peak that use over 50% of their CPU capabilities. The rest of the time, the capacity unused. By virtualizing the servers, so that additional systems can take advantage of under-utilized resources to take, IT departments can increase their return on investment (ROI). Although some companies have a consolidation ratio as high as reported 0:01, most shops, a rate slightly showing of 3.01 bis 04.01 Clock

Reduced Footprint -. By reducing the number of physical servers, the size of the computer room and reduced operating costs should decrease

lower hardware costs. – The use of a higher percentage of the available hardware resources to reduce the total number of physical servers required. This is to save money on the upfront cost of procurement of hardware and the long-term cost of maintenance.

Flexibility – Server virtualization enables IT to store much more flexible. Instead of waiting for new hardware to before arriving to introduce a new system, a new virtual server can be created on an existing computer. This also provides a flexible method for the migration and disaster recovery

Simple test and development -. Historically, IT installations have used to separate physical servers for its development, acceptance and production environments. With virtualization it is a simple process to create either different or the same operating systems on the same server. This allows developers the power to several different environments without affecting the stability of the economy compared.

Virtualization and Disaster Recovery

The growth in both international business and major natural disasters, many organizations close analysis of their disaster recovery plans and general hardware failure process. In any case, it is important to be back and running in a very short period of time. Most modern IT organizations need consistent up-time 24-hours a day to keep their core business, or their businesses are strongly affected. Both reliability and accessibility are greatly improved when server virtualization is to use the full potential.

The reduction of the total number of servers needed to duplicate the production environment, it is much cheaper to build and test an off-disaster recovery environment. Hardware, space and backup costs are reduced dramatically. It is easy to see how would the device 30 or 40 pieces of hardware configuration easier and cheaper than the 100.

In the same vein, a hardware problem is less of a problem with server virtualization. While many other systems will run on the same hardware, where most shops, they can easily duplicate physical server for the automatic rollover in the event of a hardware error, if they virtualize.

Major Virtualization Products

There are always small player in any new technology, VMware and Microsoft Virtual Server are the largest providers of server virtualization products.

VMware offers a free VMware Server package or the more robust VMware ESX and ESXi products. Systems that are virtualized by VMware products extremely portable and can be installed on almost any complications of new piece of hardware with a low incidence. The system can be suspended on a machine that moved to another, and immediately operations at the power point when it is restarted.

Microsoft Virtual Server is a virtualization product that works best with the Windows operating systems, but can also run other systems such as the popular Linux operating system.
