High available Cluster Solution

Nexenta certified logo

The Zstor HA cluster is a high-availability solution that combines shared storage, clustering and synchronous data mirroring and allows such continuous data availability and avoiding data loss at a reasonable price. As a stand-alone solution, they consist of cluster heads and disk JBODs and can afford so transparent recovery during outages so that mission-critical applications without interruption can be used further.
