 Storage Virtualization Storage virtualization basically combines/pools the storage that is available in various devices and keeps it as single storage.  Types of Storage Virtualization 1. Block Virtualization In block virtualization, we basically separate our logical storage from that of the physical so that the user/administrator can access without having to access the physical storage, basically doing this way helps the administrator in giving a lot of flexibility in managing different storage. 2. File Virtualization In File virtualization, it basically removes the dependencies caused in accessing the data at file level to that of the location where they are actually present. This basically helps in overcoming the challenges faced with network-attached storage and they also help in optimizing the storage usage and also help us to do some file migrations in a non-disruptive way. Let's create a virtual hard drive and use to share data among multiple VMs Steps:- 1. Let's creat...
