StarWind Virtual SAN Compute and Storage Separated 3 nodes with VMware vSphere

Published: August 29, 2014

INTRODUCTION

Traditionally VMware requires having some sort of the shared storage to guarantee the data safety, allow the virtual machines migration, enables continuous application availability and eliminates any single point of failure within IT environment. VMware users have to choose between two options when choosing the shared storage:

• Hyper-Converged solutions, that allows sharing the same hardware resources for the application (i.e. hypervisor, database) and the shares storage, thus decreasing the TCO and achieving the outstanding performance results

• Compute and Storage separated solutions that keeps the compute and storage layers separately from each other, thus making the maintenance easier, increasing the hardware usage efficiency and allows building the system accurately for solving the task

This guide is intended for experienced StarWind users, VMware and Windows system administrators and IT professionals who would like to configure StarWind Virtual SAN solution. It provides a step-by-step guidance on configuring a vSphere cluster using StarWind Virtual SAN to convert storage resources of the three separated general purpose servers into a fault tolerant shared storage resource for ESX.

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.
