Definition:
Storage virtualization divides physical storage into numerous devices that appear to be a single storage device. It is also a collection of available storage devices managed from a central console.
This virtualization gives several benefits, including quick data backup, achievement, and recovery. This entire process takes very little time and is quite efficient. Storage virtualization in Cloud Computing masks the true complexity of the Storage Area Network (SAN). This virtualization applies to all SAN levels.
Why is storage virtualization required?
Despite the push for digital transformation, IT departments are held back by the ongoing requirement to administer, tune, and maintain storage infrastructure that supports apps and data. To achieve high storage availability, IT must deal with hardware complexity and administrative expense.
Surveyed firms believe that fragmented data visibility across hybrid clouds creates business risk. Organizations must radically alter the piecemeal technology used to manage data and infrastructure. They must dismantle all the complexity and silos for their data and infrastructure throughout the hybrid cloud.
How can it assist enterprises?
By incorporating virtual storage into the infrastructure environment, IT can avoid overprovisioning, decrease infrastructure costs, and accelerate reaction times to any business demand. Storage virtualization allows IT to focus less on administration and more on innovation.
Furthermore, organizations that update and virtualize their storage gain a competitive advantage by reducing interruptions, limiting unexpected downtime, eliminating data migrations, and simplifying upgrades.
Various kinds of storage virtualization
Storage can deploy to a virtual environment in three ways: host-based, array-based, and network-based.
Host-based
Host-based virtualization relies on software to direct traffic, most commonly employed in HCI systems and cloud storage. This method can assign physical storage to almost any device or array. The host, a hyper-converged system made up of numerous hosts, provides virtual discs to guest machines of any configuration, such as enterprise virtual machines (VMs), PCs accessing file shares, or servers accessing data via the cloud.
Array-based
Servers are located physically in Array-based storage virtualization, and the array used is not apparent to the servers or users accessing the storage. In this case, a storage array serves as the primary storage controller, pooling storage resources from other arrays via virtualization software. Rather than a scattered collection of devices, the array can provide multiple types of physical storage as tiers. Such tiers can make up solid-state drives (SSDs) or hard disc drives (HDDs) on the various arrays.
Network-based
Network-based storage virtualization is the most popular type. A network device connects all storage devices in an FC or ISCSI SAN. Within their storage network, these networked devices appear as a single virtual pool.
Advantages to your enterprise by virtualizing your storage
Less expensive: Because virtual storage does not necessitate the normal hardware redundancy required in standard enterprise storage systems for disaster recovery, fewer appliances and software licenses are required. Virtualization saves businesses money by avoiding significant upfront financial commitments.
Time saved: Virtualized storage can reduce scheduled and unplanned downtime and make updating far less time-consuming and disruptive.
Scalability: With virtual storage, enterprises no longer need to foresee or pay for their long-term storage demands. Instead, IT can use dynamic provisioning to respond to changing demands in the market.
Easier management: Virtual storage simplifies and improves resource consumption by allowing quick storage addition/deletion without disrupting programs. It also allows for easy data movement and the implementation of additional features across the storage pool.
Reduced risk: If a disc drive, storage controller, or power supply fails, each is already replicated in the virtual array, reducing the chance of disruption. This virtual redundancy improves storage efficiency and flexibility while limiting sluggish performance.
Increased productivity: Virtual storage provides 100% availability and the potential to expedite app and service deployments, allowing for faster value realization.
Improved efficiency: The most significant advantage is faster storage with improved capacity utilization. It also improves data access and processing stability. Furthermore, virtual storage provides 100% use and little possibility of capacity exhaustion.
