Unlock enterprise-grade networking performance with the Synology E25G30-F2. This dual-port 25GbE SFP28 add-in card is purpose-built to turbocharge Synology systems, delivering blazing-fast data transfers, scalable bandwidth, and versatile connectivity options for modern data centers, virtualization environments, backups, and heavy workloads. Engineered to integrate seamlessly with Synology NAS and appliances, the E25G30-F2 combines high-throughput 25GbE networking with flexible optics and copper connections, enabling you to optimize your SAN, VM storage, and file-sharing workflows with minimal latency and maximum reliability. Whether you’re expanding an existing storage pool, migrating data between servers, or provisioning high-speed backups, this add-in card provides the performance and flexibility you need to keep your business moving.

• High-speed 25GbE connectivity: Dual 25GbE SFP28 ports deliver exceptional throughput for large datasets, virtual machines, and close-to-line storage operations, enabling faster backups, faster restores, and smoother data replication across your network. The dual-port design lets you scale bandwidth as needs grow while maintaining low latency for critical I/O activities.
• Flexible optical and copper options: Supports Optical SR, Optical LR, and DAC (direct attach cable) connectivity, giving you the flexibility to match your data center topology—from short, copper-only rack deployments to long-range, fiber-based links. This adaptability helps you minimize cabling costs and maximize network reach without changing your upgrade path.
• Designed for Synology systems: Specifically engineered for maximum performance and reliability within Synology NAS and server ecosystems. The E25G30-F2 integrates with DSM and Synology hardware to deliver streamlined configuration, efficient management, and consistent throughput across mixed workloads including virtualization, media streaming, and large-scale backups.
• Seamless scalability and reliability: Expand your network capacity with dual 25GbE ports that support link aggregation (LACP) for increased throughput and fault tolerance. Built with enterprise-grade components and thermal aware design, the card maintains performance under sustained load while fitting into standard server chassis alongside other expansion cards.
• Easy deployment with plug-and-play practicality: Designed for straightforward installation into compatible Synology systems. Once installed, you can quickly configure network interfaces, set up VLANs, QoS, and bonding/teaming policies in DSM to align with your data strategy, reducing downtime and accelerating deployment cycles.
