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. In reality, since these solutions do not require the redundancies in the hardware typically found in traditional enterprise storage systems for disaster recovery, they’re able to reduce upfront costs and ongoing operating costs by significantly.

Virtual data storage allows IT to pool physical storage devices like SANs into what appears to be an individual device, or virtual storage array. There are several ways to use this technology that include network-based storage virtualization (which blends all of the storage devices within an FC or iSCSI SAN into a single pool that is addressed via a central management console) and host-based virtualization. Host-based virtualization is often used in HCI Systems and Cloud Storage.

In order to work virtual storage, it must be compatible with underlying hardware infrastructure, networking components and servers, along with the most common management tools and hypervisors. It must also provide data encryption as well as granular access and authentication controls, as well as robust backup and disaster recovery capabilities.

Virtual storage should also be able address concerns about performance and latency. This includes ensuring that critical applications can function without impacting performance or increasing the delay of data retrieval. This requires evaluating storage controller capabilities, network bandwidth and disk I/O capacity as well as deploying caching mechanisms. It also means implementing advanced storage functions such as tiering and replication at the virtualization level.
