StarWind Virtual SAN Compute and Storage Separated Multi-Node Cluster Scale-Out Existing Deployments for VMware vSphere

Published: August 3, 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 add the Scale-Out node to the StarWind Virtual SAN® cluster. It provides a step-by-step guidance on scaling out the hyper-converged 2-node StarWind Virtual SAN that converts the storage resources of the separated general purpose servers into a fault tolerant shared storage resource for ESXi.
