Johnson’s Construction Limited completely eliminates downtime thanks to highly available failover cluster organized with StarWind Virtual SAN

Published: December 17, 2018

Does StarWind satisfy all the requirements? Absolutely. It has been tested several times with power failures and server crashes and has successfully rolled over to the operating server to avoid any downtime.

Originally, the company’s infrastructure included 5 physical servers, 3 of which were running 11 Hyper-V Virtual Machines. Aiming to eliminate downtime, Johnson’s Construction Ltd. decided to create a highly available failover Hyper-V cluster and storage. Although Microsoft Server 2012 R2 allowed to have failover cluster for the Hyper-V machines, it did not support failover for the file server which hosted the Hyper-V disks. This meant the company had a single point of failure which could be catastrophic.


After researching many sites and discussing with other IT professionals, Johnson’s Construction Ltd. opted for StarWind Virtual SAN for its reputation and reliability. The product was the perfect fit for what the company was trying to accomplish. StarWind VSAN did exactly what Johnson’s Construction Ltd. had hoped for – to have a 2-node cluster for a highly available failover file server and Hyper-V cluster. Basically, eliminating downtime. Now, the company also considers purchasing StarWind HyperConverged Appliance (HCA) and adding pre-configured hardware into the existing infrastructure.
