Slovenian Sovereign Holding (SSH) gets a highly available and fault-tolerant clustered environment with StarWind Virtual SAN (VSAN)

Published: December 5, 2019

StarWind ended as the best overall solution, feature-wise and price-performance value. Out-of-the-box product worked as specified by the vendor.

Before StarWind Virtual SAN (VSAN) deployment, SSH had a non-clustered environment with 3 physical servers and 20 virtual servers and VMware vSphere on top. With a missing stretched cluster, protecting physical machines from any hardware and software failures, achieving high availability (HA) was not possible. In addition, relying just on backup software and operating system scripts for cloning or copying virtual machines (VMs) presented too much operational risk and a lot of painstaking small jobs. Given the ever-present risk of IT infrastructure disruptions, providing data protection and meeting Recovery Point Objective (RPO) and Recovery Time Objective (RTO) requirements were open to question, not to mention the possibility of business contingency planning. Introducing shared storage into the IT environment and moving to hyperconvergence would make it possible to resolve all the company’s problems. SSH evaluated all major vendors in the market and compared the price-performance part of each solution. StarWind was the only vendor in the market who offered more for less.


SSH has chosen StarWind VSAN because it allowed creating a hyperconverged environment in one part of production in the primary data center with synchronous replication to a disaster recovery center. Thanks to StarWind synchronous failover clustering, now the company’s data and applications are running 24/7 and high availability is in place. Building a stretched cluster prevented any downtime in case of hardware failure or power outage. Delivering active-active Stretched Clustering support and VM Live Migration, StarWind VSAN ensures constant uptime for mission-critical applications. Needless to say, such a fault tolerant and highly available IT environment was built without making any changes in existing hardware resources. But more importantly, with StarWind VSAN RPO and RTO actually equal to zero since a 2-node system tolerates one disk and one node failure and keeps on operating without impacting production. Thanks to VSAN, even after six months, the IT infrastructure of SSH runs like clockwork.
