Controlling Virtual Storage area

Feb 12, 2023

Virtual storage space is a feature lets you configure a VM to work with physical or network-based storage as its virtual disk. You can also transform how electronic storage is certainly presented into a VM and adjust your data amount exhibited to a VM.

Managing virtual safe-keeping requires a cautious balance of performance, capacity and cost. IT teams need to determine the optimum number of SSDs, hard-drive hard disks or a combination of both. They must also decide which types of storage technology to implement and which usually storage controllers to use.

The regular model of storage area management should be to create and maintain disks on the RAID system level. This may involve immediate attached storage space (DAS) to a host or networks of disks including SANs.

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

Metadata and mapping: The device or perhaps software accountable for the virtualization is responsible for retaining a consistent view of all mapping facts for the virtualized safe-keeping, which is often known as metadata. This kind of mapping information is used to translate reasonable block dealing with (LBA) in physical gain access to for a logical disc or LUN.

Interoperability: The chance to exchange data between numerous devices, storage and hosts is a key factor inside the operation of your virtualized environment. Host based mostly interoperability is required for any storage controller virtualization implementation, yet network based mostly appliances must support host based interoperability to communicate with a wide range of units, including various other virtualized storage devices.
