StarWind Virtual SAN® Hyperconverged 2-Node Scenario with Hyper-V Server 2016

Published: May 25, 2018

INTRODUCTION

StarWind Virtual SAN® is a native Windows hypervisor-centric hardware-less VM storage solution. It creates a fully fault-tolerant and high-performing storage pool built for the virtualization workloads by mirroring existing server’s storage and RAM between the participating storage cluster nodes. The mirrored storage resource is then connected to all the cluster nodes and treated just as a local storage by all hypervisors and clustered applications. High Availability is achieved by providing the multipath access to all storage nodes. StarWind Virtual SAN delivers supreme performance compared to any dedicated SAN solution since it runs locally on the hypervisor and all I/O are processed by local RAM, SSD cache, and disks. This way it never gets bottlenecked by storage fabric.

This guide is intended for experienced Windows Server users or system administrators. It provides the detailed instructions on how to setup a 2-node hyperconverged Hyper-V 2016 cluster with StarWind Virtual SAN as a storage provider.

NOTE: StarWind does not recommend repeating the steps below as this process violates the Microsoft license agreement.

A full set of up-to-date technical documentation can always be found here, or by pressing the Help button in the StarWind Management Console.
