This document discusses VMware's hyper-converged infrastructure (HCI) solution using VMware vSAN software-defined storage. It begins by describing the limitations of traditional 3-tier architectures and how HCI addresses these by converging compute, storage, and networking. The document then provides details on VMware vSAN, including its features, performance advantages, market adoption rates, and pricing. It positions vSAN and VMware's HCI solution as enabling data center modernization through agility, scale, simplified management, and lower costs.
