The ubiquity of server virtualization coupled with technology advances has led to a new architecture for the Software-Defined Data Center: Hyper-Converged Infrastructure (HCI).
Hyper-Converged Infrastructure (HCI) leverages the hypervisor to deliver compute, networking and storage from a single x86 server platform, creating a tightly integrated, building block approach to IT infrastructure. HCI allows datacenters to operate with agility on a highly scalable, cost-effective infrastructure that delivers enterprise-class performance, numerous deployment choices, end-to-end integration and lower TCO.
VMware vSphere and VMware Virtual SAN are the core software technologies that constitute the foundation of VMware’s HCI solutions. vSphere and Virtual SAN are seamlessly integrated in a single layer of software that abstracts compute, storage and networking resources, delivering hyper-converged infrastructure from a single commodity x86 server hardware platform. Unique to VMware HCI is a hypervisor-centric architecture that not only converges hardware, eliminating the need for purpose-built storage appliances, but also converges the software stack in a single layer.
