Hyperconverged infrastructure (HCI) combines common datacenter hardware using locally attached storage resources with intelligent software to create flexible building blocks that replace legacy infrastructure consisting of separate servers, storage networks, and storage arrays.
A hyper-converged system allows the integrated technologies to be managed as a single system through a common tool set. Most hyper-converged systems require a minimum of three hardware nodes for high availability and can be expanded through the addition of nodes to the base unit. A grouping of nodes is known as a cluster. Hyper-convergence began in smaller use cases, such as
virtual desktop infrastructure (VDI), but enterprises now commonly use the technology to simplify the deployment, management and scaling of IT resources and to reap Capex and Opex advantages.
