The rise of software-defined storage and hyperconvergence technologies makes virtual data storage a viable option for businesses looking to cut costs in IT. These solutions can save a considerable amount of money because they don’t need the redundancy of hardware that’s typically required in traditional storage architectures for enterprises to ensure disaster recovery.
Virtual data storage allows IT to pool physical data storage devices, such as SANs, into what appears as one device or virtual storage array. There are many ways to use the technology that includes host-based virtualization as well as network-based storage (which connects storage devices from an FC or iSCSI the SAN into a single pool addressed by a central management console). Host-based virtualization can be used in HCI systems as well as cloud storage.
Virtual storage needs to be compatible with not just the hardware infrastructure itself but also with hypervisors, servers, and networking components. It should also provide encryption of data as well as granular authentication, access controls, as well as robust backup and disaster recovery capabilities.
Virtual storage should also be able to address issues with latency and performance. This includes ensuring critical applications can be run without compromising performance or causing delays to retrieval of data. This means evaluating storage controller capabilities, network bandwidth, and capacity of disk I/O as well as implementing caching mechanisms. It also involves installing advanced storage functions like tiering and replication at the virtualization level.
