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.
Active-Active architecture: 2 units in a single chassis | Active-Standby Architecture
If the active system fails, the standby system starts up and takes over processing.
- Requires purchasing two systems for HA, doubling the cost.
- Causes load imbalance as only the active system processes workloads.
- A power outage may lead to data loss.
- Network disconnection invalidates the HA architecture, rendering it ineffective.
Active-Active Architecture
Both systems are active simultaneously.
- Both controllers handle traffic, optimizing workload distribution.
- Copy-To-Flash protection safeguards data against power failure.
- Dual-path SAS interface ensures seamless connectivity.
- Efficient resource utilization, reducing computational waste.
- High-speed, uninterrupted, and high-availability storage service.
- Supports multiple communication protocols: SMB, NFS, and iSCSI.
