Key Features

• QES Operating System v2.2 Support: The ES1686dc R2 supports the upgraded QES OS, adding support for Fibre Channel SAN and NFS 4.1 for increased reliability, scalability and performance.
• Advanced Data Protection & Storage Efficiency: Powered by the ZFS-based QES OS, the ES1686dc R2 offers inline data deduplication and compression for maximum storage efficiency. Self-healing mechanisms prevent silent data corruption, and users can benefit from near-unlimited snapshots for iSCSI LUNs and shared folders, plus SnapSync for accelerated remote backups.
• High Availability & Performance: Dual active-active controllers ensure near-zero downtime, while an NVRAM module enhances data protection during power failure.
• High-Speed Networking: Each controller features four 10GbE SFP+ ports, plus two PCIe slots for adding 10GbE/25GbE network cards to boost virtualization, media file transfer, and other bandwidth-demanding applications.
• Optimized for Virtualization: Compatible with VMware®, Microsoft®, and Citrix® virtualization platforms. SnapSync integrates with VMware Site Recovery Manager (SRM) for enterprise-class remote backup and disaster recovery. iSER protocol support enhances VMware performance.
• Storage Pool Expansion: Users can expand storage pool capacity by replacing the disks and clicking a few buttons in the Storage Pool Management interface. The UI displays the approximate capacity expansion, allowing businesses to prepare for growing data.
• Petabyte-scale, Dual-controller SAS Storage Expansion: Scale up to petabytes by connecting up to sixteen 16-bay QNAP SAS expansion enclosures. Dual-channel (dual-path) connections ensure uninterrupted service even during a node failure.
