What is Hyper-Converged Infrastructure?

Hyper-Converged infrastructure 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.


Hyperconverged infrastructure (HCI) is a distributed infrastructure platform that integrates servers and storage with intelligent software to construct scalable building blocks that replace legacy infrastructure that consists of separate servers, storage networks, and storage arrays. To remove common pain points associated with legacy infrastructure, it combines commodity datacenter server hardware with locally attached storage devices (spinning disc or flash) and is operated by a distributed software layer.
