Four 10GbE SFP+ ports accelerate virtualization, large file sharing, and intensive data transfer.

Real-time SnapSync

Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.

Virtualization applications

Supports VMware® vSphere® 6.5, Windows Server® 2016 and Citrix® XenServer® 7.0 for storage virtualization. Compatible with OpenStack® cloud environments.

Active-Active high availability with optimal storage efficiency

In Active-Active storage system architecture, both controllers are able to provide a complete range of services, which is different from the Active-Standby architecture of single-controller systems. The Active-Active architecture does not have the disadvantage of idle computing resources. To leverage the strengths of the ES1686dc Active-Active controller architecture, it is recommended to create multiple storage pools and distribute their ownership between both controllers. This allows simultaneous output from both controllers for better load balancing.

Active-Standby single-controller system

With two HA systems you are paying twice the price and causing a load imbalance as workloads are only processed on the active system. A power outage could cause data loss, and the disconnected network invalidates the HA architecture.
