Virtualization


Virtualization is the technique of masking or abstracting physical resources, which simplifies the infrastructure and accommodates the increasing pace of business and technological changes. It increases the utilization and capability of IT resources, such as servers, networks, or storage devices, beyond their physical limits. Virtualization simplifies resource management by pooling and sharing resources for maximum utilization and makes them appear as logical resources with enhanced capabilities.

As storage networking technology matures, larger and complex implementations are becoming more common. The heterogeneous nature of storage infrastructures has further added to the complexity of managing and utilizing storage resources effectively. Specialized technologies are required to meet stringent service level agreements and to provide an adaptable infrastructure with reduced cost of management. The virtualization technologies discussed in this module provide enhanced productivity, asset utilization, and better management of the storage infrastructure.
