The virtualization of servers transforms a set of servers, storage devices and networks into a pool of computer resources. It consists of a virtual layer, which allows that several virtual machines, with different operational systems, can be executed in isolation, side by side, on the same physical machine.
In other words, it allows a server to execute multiple operational systems or applications in different partitions, which can be configured to meet specific needs, without one interfering in the operation of the other. This technology can be used from software or hardware tools.
The process basically consists of: Survey > Dimensioning > Purchase > Migration > Operation. .
Incentives for the virtualization of your environment:
- Scalability;
- Management costs;
- Guarantee of availability an d performance;
- Increase of infrastructure control;
- Increase in the processing power of Intel and AMD processors;
- Use of processing idleness;
- Dissemination of Windows and Linux operational systems;
- Freedom to choose hardware and software;
- Reduction of equipment and electric energy costs;
Main benefits provided by this service:
- Use of machines' processing idleness;
- Reduction of the physical space needed to store them;
- Reduction of the equipment's energy consumption;
- Reduction of the dissipation of heat and consequently, the need for cooling (a major energy consumer) (The environment is grateful);
- Reduction of network cable connections. Less cables mean less switch ports;
- Reduction of electrical outlets and cables;
- Reduction of HBA's and Fiber Channel Switches for storage access/
- With all these measures, we reduce the environment's complexity and indirectly centralize management;
- And there is also restraint, which means that when a new server is needed, all that needs to be done is create a new virtual machine.
