Four 10GbE SFP+ ports accelerate virtualization, large file sharing, and intensive data transfer.
Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.
Supports VMware® vSphere® 6.5, Windows Server® 2016 and Citrix® XenServer® 7.0 for storage virtualization. Compatible with OpenStack® cloud environments.
- Available with 64GB, 96GB or 128GB memory.
Active-Active high availability with optimal storage efficiency
In Active-Active storage system architecture, both controllers can provide a comprehensive range of services, which is different from the Active-Standby architecture of single-controller systems. An advantage of Active-Active architecture is the lack of idle computing resources. To leverage the strengths of the QNAP ES1686dc-2142IT-128G Active-Active controller architecture, QNAP recommends creating multiple storage pools and distributing ownership between both controllers to enable simultaneous output from both controllers for improved load balancing.
With two HA systems you are paying twice the price, and the HA system can cause load imbalances because workloads are only processed on the active system. Moreover, a power outage can cause data loss, while network disconnections will invalidate the HA architecture.
Both controllers of the ES1686dc can carry traffic, along with Copy-To-Flash protection against power failure and the dual-path SAS interface. Besides conserving computing resources, a high-speed, uninterrupted, and high-availability storage service is also provided through communication protocols such as SMB, NFS and iSCSI.
