Storage virtualization abstracts the space available in physical hardware into software-defined storage that is accessible by any end-user device. It allows multiple storage devices to appear as a single monolithic volume www.myvirtualstorage.blog/the-impact-of-the-bet-data-room-software/ and improves the management of data by removing the need to anticipate long-term storage needs and pay for additional capacity upfront.
Virtualization can be achieved in two ways: host-based or network-based. Host-based virtualization (typically employed in HCI systems and cloud storage) makes use of software to manage traffic. The host or hyper-converged systems made up of multiple hosts, offer virtual drives to guest machines of any configuration, whether they are virtual machines in enterprise environments, computers that connect to file servers, and servers that store data in cloud. The host makes use of software that converts the logical address of each block of disk data into an offset within a logical drive.
Network-based virtualization employs a different approach, transferring the complexity of a storage controller onto an upper layer over the virtualization hardware. This often requires additional components, like a network switch, in order to manage the increased I/O load. However, it is able to reduce costs while increasing performance.
The layer over the virtualization hardware also gives the capability to perform backup and recovery functions without being impacted by the virtualization. It also allows you to troubleshoot issues remotely – either by internal IT teams or managed service providers which can improve resolution speed. In addition, it helps in scalability by removing dependencies between the location of files that are accessed at the level of file and where they are physically stored on physical disks. This can help optimize storage usage, server consolidation, and conducting non-disruptive migrations of files.
