How Virtual Data Storage Can Lower IT Costs

Virtual data storage is becoming an increasingly popular option for companies who want to reduce their IT costs. In actual fact, since these Find Out More solutions don’t require the hardware redundancies typically needed in traditional enterprise storage systems for disaster recovery, they could reduce upfront costs and operating expenses over time by an impressive amount.

Virtual data storage allows IT to pool physical data storage devices like SANs into what appears as an individual device or virtual storage array. There are several ways to utilize the technology such as host-based virtualization and network-based storage (which integrates storage devices from an FC or iSCSI SAN in one pool controlled by a central management console). Host-based Virtualization is typically found in HCI Systems and Cloud Storage.

To function, virtual storage must be compatible with the hardware infrastructure including networking components, servers and other servers, along with the common management tools and hypervisors. It must also support encryption of data, granular access and authentication controls, as well as robust backup and disaster recovery capabilities.

Virtual storage must also be able to address issues with latency and performance. This includes ensuring that critical applications are able to run without hindering performance or increasing the delay of data retrieval. This involves evaluating the storage controller’s capabilities, network bandwidth, and capacity for disk I/O as much as deploying caching mechanisms. It also requires the use of advanced storage functions such as tiering, replication and virtualization at the virtualization layer.
