• 4 x 10GbE SFP+ ports

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

• Reliable & High-performance

  Battery-protected DRAM write to cache data protection and Flash read acceleration provides industry-leading random access performance.

• 2 x PCIe Gen 3 slots

  PCIe expandability allows for 10GbE/25GbE adapters to increase application performance.

• 4 x 10GbE SFP+ ports

  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.

• Dual controller NAS: High reliability and high availability

  Intel® Xeon® D dual active-active controllers provide supreme uptime and redundancy to ensure high availability.

• Multi-level cache technology with both read and write

  The ES1686dc simultaneously supports main memory read cache (L1 ARC), SSD secondary read cache (L2 ARC), and memory write cache (ZFS Intent Log) to meet performance demands for various enterprise applications.

  • Up to 512 GB main memory

    Each controller has eight RDIMM slots, allowing for up to 512 GB memory.

    Note: The main memory will retain 8GB for use by the write cache.

  • NVRAM cache reduces the risk of losing write cache data

    If unplanned power outages occur, the system can write cache data from the battery-protected DRAM to M.2 SSD through Copy To Flash (C2F) to ensure that data is not lost.
