What is Hyper-Converged Infrastructure (HCI)?


Hyper converged infrastructure (HCI) allows the convergence of physical storage onto industry-standard x86 servers, enabling a building block approach with scale-out capabilities. All key data center functions run as software on the hypervisor in a tightly integrated software layer – delivering services that were previously provided via hardware through software.


Introduction to Hyper-Converged Infrastructure

What is VMware’s Industry-Leading Software for Hyper-Converged Infrastructure (HCI)?

VMware provides a unique, software-defined approach to hyper convergence, leveraging the hypervisor to deliver compute, storage and management in a tightly integrated software stack. 

HCI powered by vSAN consists of:

  • vSphere: our industry-leading virtualization platform that provides server virtualization.
  • vSAN: the only vSphere-embedded storage solution that delivers flash-optimized, high-performance, hyper-converged storage for virtual machines.
  • vCenter Server: the unified and extensible management solution for vSphere environments.

HCI powered by vSAN gives you the broadest choice of hardware deployment options. The vSAN ReadyNode program includes more than 150 certified x86 systems available from all the major server vendors. Dell EMC VxRail is a turnkey hyper-converged infrastructure appliance, jointly engineered by VMware and Dell EMC, which offers the most streamlined deployment experience.

Hyper-Converged Infrastructure powered by vSAN: Deployment Options 

Dell EMC VxRail

The Dell EMC VxRail appliance, exclusively available from Dell EMC and VMware, is the easiest and fastest way to implement a VMware powered HCI solution. With the power of a whole SAN in just 2 rack units, it provides a simple, cost effective hyper-converged solution for a wide variety of applications and workloads. With VxRail, IT organizations can start small and easily scale capacity and performance by non-disruptively adding appliances to the cluster without the investment or up-front planning required with traditional infrastructure.

vSAN ReadyNode

vSAN ReadyNode are the most flexible x86 building blocks on which to deploy VMware hyper-converged infrastructure software. We have partnered with all the leading x86 server vendors to provide a broad choice of pre-certified hardware, enabling you to deploy hyper-converged infrastructure with maximum flexibility of hardware, software, licenses and support.
