A survey on design and implementation of out-of-band storage virtualization

Over the past several years, virtualization has evolved from a popular buzzword into a formidable strategic technology that many organizations have adopted and many others are strongly considering. This study paper revolves around the impact of virtualization at the various layers of storage stack. There is a rapid growth in the storage capacity, and hence the processing power in the respective enterprise's storage appliances coupled with the requirements for high availability and it needs a Storage Area Network (SAN) architecture for providing the storage and performance elements here. The Storage Virtualization provides us with a combination and management of storage resources for Storage Area Network with multiple servers as well as the storage devices. The main aim for storage virtualization is its necessity to be inexpensive and not affect the performance. This paper focus as on how virtualization helps security, Memory Management, Power Management and Disaster Recovery.
