    PRODUCT OVERVIEW DELL EMC VXRACK SYSTEM 1000 SERIES Hyper-Converged Infrastructure at scale Converged infrastructure brings together the disparate infrastructure elements that power IT, including servers, data storage devices, networking functions, virtualization, management software, orchestration, and applications. The purpose: To simplify IT by breaking down the silos in the data center, reversing the status quo of static and inflexible pools of resources. Converged infrastructure solutions are proven to significantly speed deployments, make infrastructure more agile, and simplify IT operations—all of which is critical to successfully deliver IT as a service. In contrast to traditional converged infrastructure solutions, hyper-converged infrastructure (HCI) is a software-defined architecture with integrated compute, networking, software-defined storage, and virtualization. It enables compute, storage, and networking functions to be decoupled from the underlying infrastructure and run on a common set of physical resources that are based on VxRack System industry-standard x86 components. Using hyper-converged infrastructure, customers can start with 1000 Series a small deployment, and then flexibly scale out to support dynamic workloads and evolving Modular hyper-converged infrastructure business needs. system that delivers extreme scalability The VxRack System 1000 series is a hyper-converged platform that complements Dell EMC and flexibility converged infrastructure systems. These self-contained units of servers and networking are well
