Controlling Virtual Storage space

Virtual storage area can be described as feature that allows you to configure a VM to use physical or network-based storage as the virtual hard disk drive. You can also enhance how electronic storage is presented to a VM and adjust the results amount displayed to a VM.

Managing virtual storage requires a careful balance of performance, capacity and cost. THAT teams must determine the optimum number of SSDs, hard-drive disks or a mix of both. They have to also choose types of storage technology to put into action and which usually storage remotes to use.

The traditional model of storage space management should be to create as well as disks at the RAID program level. This may involve immediate attached storage space (DAS) into a host or networks of disks such as SANs.

A storage virtualization architecture commonly replaces this traditional storage area model by providing a central stage of control for the creation and maintenance of physical storage. This central point of control can be put in place within a storage area controller or maybe a networked home appliance that deals with and attaches to other storage space devices.

Metadata and mapping: The device or software accountable for the virtualization is responsible for preserving a regular view of all mapping information for the virtualized storage, which is often known as metadata. This mapping details is used to translate reasonable block responding to (LBA) in physical gain access to for a logical hard drive or LUN.

Interoperability: A chance to exchange info between different devices, storage area and owners is a key factor inside the operation of the virtualized environment. Host founded interoperability is necessary for any storage controller virtualization implementation, yet network established appliances anonymous must support host structured interoperability to communicate with a wide range of units, including various other virtualized storage space devices.
