How Virtual Data Storage Can Lower IT Costs

Virtual data storage is now an increasingly popular option for businesses who want to reduce their IT costs. These solutions can save a significant amount of money as they don’t need the hardware redundancy that is typically required in traditional enterprise storage systems to ensure disaster recovery.

Virtual data storage enables IT to pool physical storage devices, such as SANs, into what appears as an individual device or virtual storage array. There are several methods to implement this technology using network-based storage (which brings together all of the storage devices of an FC or iSCSI storage area into a single pool, which is managed by a central management console) and host-based virtualization. Host-based virtualization can be found in HCI systems and cloud storage.

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

Furthermore, virtual storage should be able to handle issues of latency and performance. This includes ensuring that critical look these up software are able to run without compromising performance or causing delays to data retrieval. This requires evaluating storage controllers, bandwidth for networks and capacity of disk I/O as well as deploying cache mechanisms. It also requires the use of advanced storage functions such as replication, tiering, and virtualization at the virtualization layer.
