Managing Virtual Safe-keeping

Virtual safe-keeping can be described as feature lets you configure a VM to use physical or network-based storage as the virtual disk. You can also transform how virtual storage is presented into a VM and adjust your data amount exhibited to a VM.

Managing virtual safe-keeping requires a careful balance of overall performance, capacity and cost. THIS teams must determine the optimum number of SSDs, hard-drive hard disks or a mix of both. They must also choose types of storage technology to put into practice and which in turn storage controllers to use.

The regular model of storage management is to create and maintain disks in the RAID system level. This may involve direct attached storage area (DAS) into a host or perhaps networks of disks including SANs.

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

Metadata and umschlüsselung: The device or software responsible for the virtualization is responsible for keeping a consistent view of all of the mapping data for the virtualized storage area, which is known as metadata. This mapping data is used to translate logical block handling (LBA) in to physical access for a logical hard drive or LUN.

Interoperability: Being able to exchange information between numerous devices, storage space and owners is a key factor in the operation of the virtualized environment. Host based mostly interoperability is necessary for any storage controller virtualization implementation, nonetheless network structured appliances must support host centered interoperability to communicate with a wide range of products, including additional virtualized storage space devices.
