Hyperconverged Infrastructure (HCI) is a software-defined IT infrastructure server. Instead of using hardware to operate each server element (such as storage, network and compute), the infrastructure elements exist as software, which is known as virtualization.
IT administrators can easily create virtual infrastructure within HCI servers. This enables fast application and resource deployment. Since it takes up less space and is easier to cool, HCI can also reduce IT infrastructure costs.
HCI servers are built by the manufacturer, so they can’t be customized. This contrasts with converged infrastructure, which is modular in design.
