How Virtual Data Storage Can Lower IT Costs

Virtual data storage is gaining popularity as an increasingly popular choice for companies looking to cut down on IT expenses. These solutions can save a lot of money because they don’t need the redundant hardware required in traditional enterprise storage systems to ensure disaster recovery.

Virtual data storage allows IT to pool physical storage devices such as SANs into what appears as a single device, or virtual storage array. There are a variety of ways to use this technology such as network-based storage virtualization (which integrates all the storage devices in an FC or iSCSI SAN into a single pool that is addressed 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 with the underlying hardware infrastructure but also with servers, hypervisors, and networking components. It must also support encryption of data, granular access and authentication controls, as well as robust backup and disaster recovery capabilities.

Furthermore, virtual storage should be able to tackle the issues of performance and latency. This includes ensuring that critical applications are able to run without impairing performance or adding to the latency of data retrieval. This requires evaluating the performance of storage controllers, network bandwidth and capacity of disk I/O as well as using cache mechanisms. It also involves the use of advanced storage functions like tiering, replication and virtualization at the virtualization layer.
