Features
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.
