How Virtual Data Storage Can Lower IT Costs

Virtual data storage is becoming an increasingly popular choice for companies looking to cut down on IT expenses. These solutions can save amount of money since 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 departments to pool physical storage devices, like SANs, into what appears to be http://www.virtualdataspace.biz/box-vdr-main-features/ one device or storage array. There are many ways to utilize 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 typically found in HCI systems as well as cloud storage.

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

Virtual storage should also be able address concerns regarding latency and performance. This includes ensuring critical applications are able to run without compromising performance or causing delays to data retrieval. This includes assessing storage controllers, bandwidth for networks and capacity of disk I/O as well as using cache mechanisms. It also involves installing advanced storage features, like replication, tiering, and virtualization at the virtualization layer.
