Storage virtualization is the process of abstracting an actual storage device (such as disks) and turning it into accessible to multiple owners. It can be used to raise storage usage by storing data files on devices that are not being utilized, or perhaps it can increase what is a bolt-on acquisition disaster recovery.
Several forms of data storage could be virtualized: Network-based, NAS document and prevent, tape media, and other types of archival and back up targets. This may make numerous storage products available to numerous users, while making it easier to deal with those devices.
Cloud Safe-keeping
Cloud Safe-keeping is a model where info is kept on remote servers in the cloud, commonly in data centers throughout the world. It is usually provided on a membership or pay-as-you-go basis and can be very easily scaled up or down for the reason that required.
The advantages of virtualization incorporate:
Easier managementStorage administrators may monitor and observe after a pool area of multiple safe-keeping arrays with a single unit, which saves time and effort. This is particularly helpful when the storage space systems originate from different vendors.
Lower costs
The price tag on managing online storage is certainly significantly lower compared to other storage types. This is due to the less complicated architecture and fewer assets that are necessary.
Data Migration
During storage area migration, the meta-data mapping of an logical disc is updated so that it take into account a new physical location. This really is done non-disruptively while the a lot continues to operate I/O for the logical drive. The granularity of the mapping can often be critical and determines simply how much extra capacity is required during the migration, and just how quickly the previous location is normally marked when free.
