Optional Solutions


  • Nexenta MetroHA™ delivers a high availability cluster configuration of NexentaStor and provides storage redundancy, high availability, and disaster recovery over campus and metro-wide distances (up to 30 miles/50 kilometers).
  • This software-based product enables IT organizations to protect business critical data easily and cost effectively. Nexenta MetroHA configurations contain at least two complete copies of specified file systems or data volumes separated by geographical distance. Copies can be synchronously updated for full redundancy and fail-over.
  • Because this is a true clustered storage solution, the active-active pair is managed from a single location. In addition, administration, configuration, and maintenance for the primary and secondary site are simplified. This reduces overhead, personnel costs, and the risk of configuration inconsistencies that can arise between two or more arrays.
