StarWind Virtual SAN® Scale-Out Architecture

Published: September 2015

Scale-out by StarWind Virtual SAN is the approach with the modern virtualization trend in mind. It is a much more efficient and cost-effective alternative to scale-up. The idea behind scale-out is to grow both storage and compute power by adding additional nodes instead of adding disks, CPUs, NICs or RAM to individual systems. Increasing the number of nodes increases reliability by eliminating single points of failure. It also gives customers a more flexible computing environment by treating all servers as a unified compute and storage resource pool. Adding nodes with the same hardware configuration isn’t necessary. Customers can add performance-tuned or capacity-tuned nodes depending on their IT environment requirements.
