Enterprise Storage OS for High Availability 

Open-E JovianDSS Advanced Metro High Availability Cluster Feature Pack

Advanced Metro HA Cluster – Benefits

  • 1Gbps, 10Gbps, 40Gbps, 100Gbps Ethernet support for maximum speed
  • Perfect for both rack (from 12" / 30cm) and metro (up to 50 miles / 80km) clusters
  • Allows use of less expensive SATA drives
  • Easy to configure and manage
  • Compared to SAS or FibreChannel, JBODs are not required for Ethernet clusters
  • Optional use of RAID controllers

Advanced Metro High Availability cluster for SMB, NFS and iSCSI

Open-E JovianDSS includes failover functionality for SMB, NFS and iSCSI, enabling you to set up High Availability Load-Balanced Storage Clusters that ensure reliability and redundancy through failover in case of a server crash. By using the Open-E JovianDSS Advanced Metro High Availability Cluster Feature Pack, you can create High Availability for two server nodes with storage mirror over Ethernet using a storage at each location (Dual Storage).

Since the connection of cluster communication and data mirroring between nodes works over Ethernet, the nodes might be located far from each other as a (stretched) metro storage cluster. It can be 50 miles (80 km) in case of point to point fibre optic connection, or even more when using an additional switch between nodes - provided that network latency will not exceed 5 ms. The Feature Pack also supports configurations of the Open-E JovianDSS Standard HA Cluster Feature Pack.
