Synology Dual-Port 10GbE Adapter

The Synology Dual-Port 10GbE Adapter is the essential upgrade for businesses that demand scalable, high-speed networking for their Synology NAS or DiskStation systems. Built to deliver reliable 10 Gigabit Ethernet performance, this dual-port SFP+ network adapter accelerates data-intensive workloads—from large backups and virtual machine migrations to media editing pipelines and multi-user file sharing. With two independent 10GbE interfaces, you can implement link aggregation for maximum throughput, enable fault tolerance, and simplify network topology by consolidating multiple servers or workstations onto a single storage infrastructure. This adapter is designed for enterprise-grade reliability and seamless DSM (DiskStation Manager) compatibility, ensuring a smooth, high-performance upgrade path for growing networks.

• Powerful dual-port 10GbE SFP+ connectivity: Experience blistering data transfer speeds with two dedicated 10GbE ports that can operate independently or in tandem for aggregated bandwidth. This enables large-scale backups, fast VM migrations, and rapid data transfers across your network.
• Seamless Synology DSM integration: Engineered to work flawlessly with Synology NAS and DiskStation devices, providing automatic detection and configuration within DSM 7.x and beyond. Enjoy a streamlined setup experience and centralized management through your existing Synology ecosystem.
• Advanced networking features: Supports link aggregation (LACP) and failover, helping you maximize throughput while maintaining continuous access during switch or link failures. Perfect for high-availability deployments and busy data centers.
• Flexible cabling options: Use SFP+ fiber modules or Direct Attach Copper (DAC) cables to match your existing data center cabling strategy and equipment. This flexibility makes it easy to integrate into a range of network architectures, from small offices to enterprise campuses.
• Scalable for growth: Ideal for virtualization, backups, remote site replication, and large-scale file transfers, making it a future-ready upgrade as your network demands rise. As your workload expands, you can leverage the two ports to balance traffic, reduce bottlenecks, and optimize storage performance.

How to Install Synology Dual-Port 10GbE Adapter

• Power down your NAS, unplug all cables, and remove the chassis cover to access PCIe slots. Ensure you’re grounded to prevent static damage.
• Locate an available PCIe slot that fits the adapter. Remove the slot cover if necessary and prepare the slot for installation.
• Insert the Synology Dual-Port 10GbE Adapter firmly into the PCIe slot and secure it with a mounting screw if required. Make sure the card is seated evenly and fully.
• Replace the chassis cover, reconnect power, and boot the NAS. Allow the system to initialize hardware and detect the new PCIe device.
• Open DSM (DiskStation Manager). The adapter should be detected automatically; if prompted, install any recommended firmware or driver updates. Configure the NICs as needed in Network settings.
• Connect two 10GbE cables (SFP+ modules or DAC) from the adapter’s ports to your switches or servers. In DSM, set up Link Aggregation if you plan to use NIC teaming, and ensure the corresponding switch configuration (LACP) matches for optimal throughput and fault tolerance.

Frequently Asked Questions
