Storage virtualization is the sharing of physical storage into multiple storage devices which further appears to be a single storage device. It can be also called as a group of an available storage device which simply manages from a central console.
This virtualization provides numerous benefits such as easy backup, achieving, and recovery of the data. This whole process requires very less time and works in an efficient manner. Storage virtualization in Cloud Computing does not show the actual complexity of the Storage Area Network (SAN). This virtualization is applicable to all levels of SAN.
Why is storage virtualization needed?
Despite the drive for digital transformation, IT departments are held back by the constant need to administer, tune, and maintain storage infrastructure that supports apps and data. In fact, to achieve high storage availability, IT deals with a great deal of hardware complexity and overhead cost.
A recent survey of IT decision-makers conducted by ESG for HPE found that 93% see storage and data management complexity impeding digital transformation. And 67% of surveyed organizations see fragmented data visibility across hybrid cloud creating business risk. That means enterprises must fundamentally change the piecemeal technology used to manage data and infrastructure. They need to break down all the complexity and silos for their data and infrastructure across the hybrid cloud.
How can it help enterprises?
By including virtual storage in the infrastructure environment, IT can avoid overprovisioning, reduce infrastructure costs, and speed up response times to any business need, enabling IT to focus less on administration and more on innovation.
Additionally, enterprises that modernize and virtualize their storage gain a competitive advantage with fewer disruptions, limited unplanned downtime, no data migrations, and no complex upgrades.
How does storage virtualization work?
In storage virtualization, physical storage hardware is mirrored in a virtual volume. To construct a simple virtual storage environment, multiple physical disks are combined into a grouping that uses a single server. Virtual storage or logical storage blocks are assigned to the same server and help to redirect the input/output (I/O) traffic.
