Modern world business success directly depends on its applications and services availability. These should run 24/7/365 and the storage backend should be able to support this by providing High Availability. This means not just being able to withstand a component failure but also to resume full operation as soon as possible.
StarWind ensures High Availability for applications and services by performing storage synchronous replication between the nodes. However, it is also ultimately important for the synchronization process to complete as fast as possible, in case it was disrupted for any reason. Synchronization of large storage volumes can take a long time, making applications more vulnerable to additional failures, which can lead to downtime.
