Ensure uninterrupted mission-critical business operations with the high-availability ES1686dc R2 NAS. With redundant controllers and power supplies, it minimizes downtime, allowing seamless component replacement without disruption, ensuring reliability and continuity for enterprises.

 

  • Dual active-active controllers

    Dual active-active controllers provide supreme uptime and redundancy to ensure high availability.

  • NVRAM module

    NVRAM reduces the risk of losing write cache data if unexpected power failure occurs.

  • QES operating system

    Supports ZFS near-limitless snapshots, SnapSync, block-level data deduplication, and inline data compression.

  • Storage for virtualization

    Supports VMware® vSphere®, Windows Server® and Citrix® XenServer® for storage virtualization.

  • 10GbE SFP+ ports

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

  • PCIe Gen 3 slots

    Two PCIe slots (per controller) allow for adding 10GbE/25GbE networking cards to increase application performance.
