Virtual data storage is now an increasingly popular option for businesses looking to cut down on IT expenses. In actual fact, since these solutions don’t require the redundant hardware that is typically required in traditional enterprise storage systems for disaster recovery, they could reduce both upfront expense and ongoing operating costs by substantial amounts.

Virtual data storage allows IT departments to pool physical storage devices, like SANs, into what appears to be an individual device or storage array. There are a variety of ways to implement this technology such as network-based storage virtualization (which brings together all of the storage devices within an FC or iSCSI storage system into a single pool that is managed via a central management console) and host-based virtualization. Host-based Virtualization can be used in HCI Systems and Cloud Storage.

Virtual storage should be compatible not just with the hardware infrastructure itself but also with servers, hypervisors, and networking components. It should also be able to support encryption of data and access controls, as well as robust backup and disaster recovery capabilities.

Virtual storage must also be able to address issues with latency and performance. This means that crucial applications run without impairing performance or adding to the latency of data retrieval. This involves evaluating the storage controller’s capabilities, network bandwidth and capacity of the disk I/O, as well as implementing caching mechanisms. It also requires installing advanced storage functions like tiering and replication at the virtualization level.
