A virtual machine is a replica of a physical machine in all rights and with respect to the building components, regardless of the fact that it is emulated, resembles, and delivers the same performance as a physical machine. Every computer ought to have storage for the OS or application loading. This condition applies to virtual machines as well. If VMs are serving as independent servers for roles such as domain controller or file server, where the server needs to maintain additional storage apart from the OS, the extended storage can be extended for domain user access without any performance degradation.

Virtual machines can benefit from multiple forms of storage, namely VHD/VHDX, which are file-based storage; iSCSI LUNs; pass-through LUNs, which are raw device mappings; and of late, virtual-fibre-channel-assigned LUNs. There have been enhancements to each of these, and all of these options have a straightforward implementation procedure. However, before you make a selection...
