Hyperconverged infrastructure (HCI) involves using a server’s local storage, coupled with software-defined storage (SDS), to create a virtual SAN whose storage is accessible from all the nodes in an HCI cluster. Using HCI, storage and compute are managed from the same console. To add compute and storage in a HCI cluster you only need to purchase additional HCI nodes instead of, as with legacy data center topologies, having to buy storage, integrate it with servers and then manage your storage and compute using different management consoles. Despite its advantages HCI is not a cure-all for data center woes; in fact, we are seeing an over-reliance on HCI adversely affecting the data center’s economics. Enterprises are now looking at alternatives, such as HPE’s distributed HCI (dHCI) solution that incorporates HPE’s ProLiant servers, Nimble Storage and M-series network switches as an alternative to HCI as it gives the benefits of HCI while removing the drawbacks of it.

HCI involves using a server’s local storage, coupled with software-defined storage (SDS), to create a virtual SAN (vSAN) that is shareable with other HCI nodes in an HCI cluster. With HCI, you only need to purchase a single node to add compute and storage instead of the alternative: having to buy separate storage arrays and manage them from different management consoles, as well as servers and the need to deal with integrating them.
