Storage Virtualization Brings Efficiency, Manageability and Flexibility to the Storage Environment.
Businesses of all sizes are turning to server virtualization and many are beginning to take advantage of virtualized storage to help increase efficiency, reduce costs and make their IT organizations more manageable and flexible. A single logical resource is formed by virtualizing your storage environment. This is accomplished by allowing the storage available on multiple systems to aggregate the disk pools. This virtualized storage pool can then be provisioned for use by servers, applications or by individual users.
Storage utilization can be significantly improved, often by 80% or more, by pooling storage resources into a single source. All of the space can then be managed by server or storage administrators, utilizing a single administration console, regardless of where the servers or SANs are located.
The single administrative pane of glass allows the administrator to easily see growth patterns and utilization trends more clearly, making better storage capacity planning or upgrade decisions more manageable. The size of the LUN can now be increased or decreased as needed by thinly or dynamically provisioning the new virtualized storage environment, and not necessarily devoting a hard allocation of 500GB of storage where there’s only a need today of 200GB.
Migration or replication of data in the storage pools between geographic locations or systems is now made extremely flexible since the storage space is decoupled from the storage array or physical disk. For example, the ease of replicating a virtual LUN to another local or off-site storage location for backup or disaster recovery purposes. Data that is higher priority and get more usage can be elevated to a higher data tier, and vice versa.
By utilizing the available resources already available on multiple systems your IT department can take full advantage of disk resources rather than spending money on additional capacity. Storage Virtualization can also reduce the cost of maintenance, by helping to sweat the assets and improve ROA over time.
