Virtual storage can be described as feature that allows you to configure a VM to work with physical or network-based storage as its virtual disc. You can also transform how electronic storage can be presented into a VM and adjust the information amount displayed to a VM.

Managing virtual safe-keeping requires a very careful balance of efficiency, capacity and cost. IT teams must determine the best number of SSDs, hard-drive hard disk drives or a combination of both. They must also choose types of storage technology to put into action and which storage controllers to use.

The original model of safe-keeping management is always to create and maintain disks at the RAID program level. This could involve direct attached storage (DAS) into a host or perhaps networks of disks including SANs.

A storage virtualization architecture typically replaces this kind of traditional storage area version by providing a central stage of control for the creation and maintenance of physical storage. This kind of central point of control can be executed within a safe-keeping controller or maybe a networked equipment that handles and attaches to other storage devices.

Metadata and mapping: The device or perhaps software responsible for the virtualization is responsible for preserving a consistent view of all the mapping data for the virtualized safe-keeping, which is often known as metadata. This kind of mapping details is used to translate logical block addressing (LBA) into physical access for a logical drive or LUN.

Interoperability: The capability to exchange information between diverse devices, storage and hosts is a key factor inside the operation of any virtualized environment. Host established interoperability is necessary for any storage space controller virtualization implementation, yet network structured appliances must support host depending interoperability to communicate with a wide range of devices, including various other virtualized storage devices.
