Deep Dive Into Storage Virtualization By Shivam and Rishabh
Fig 1 So firstly the question arises what is storage virtualization? We can say that it is a group of physical storage from multiple network storage which appears to be a single storage device. Through this technique, the user does not have to be worried about the location of their data, which can be identified using a logical path Reasons which bring us to storage virtualization:- 1. Better storage utilization. 2. Managing storage becomes easier. 3. Availability of data increases. 4. Improved backup and recovery process. 5. Data replication and disaster recovery. All these features are present because storage virtualization uses the most popular technique to store data known as SAN (Storage Area Network). Storage Virtualization consists of SAN and Object storage (HTTP). Before proceeding with SAN we should take a look around other storage techniques: 1. NAS (Network Attached storage) 2. DAS (Direct Attached storage) 3. SAN (Storage Area Network)...
