Virtualization is a way to create systems that are less complex subsets of the division of systems into more manageable devices. In addition, this measure can give more security to the system, network and applications, as it isolates potentially vulnerable subsystems underlying systems and other virtual platforms.
The concept of virtualization includes all layers of the platform – from applications and operating systems components, processors and interconnections of the platform. But let’s stick to the storage devices and dedicated servers, because these environments are the most active market for virtualization.
An essential tool for all this virtualization work, is the Storage, which is a site designed and suitable for data storage.
Storage virtualization is the process of consolidating multiple physical devices from different manufacturers and rearrange them in clusters, virtual and logical, or storage units. These units are presented to the operating system for use by applications and end users.
Networked storage allows connectivity between all servers and storage devices, and also increases the capacity of organizations to migrate their data. Networked storage can reduce the costs of information processing, by increasing the sharing of devices and capabilities, as well as through more efficient communications.
For example, a virtual storage pool can be created by using the physical disks faster in order to optimize performance for a mission critical application, while protecting the user and the application details of hardware implementation. There are many technologies of “virtualization” of storage that have evolved, including solutions for internal and external bandwidth (in-band and out-band) based storage and hosting.
