Synology E25G30-F2 2-Port 25GbE SFP28 PCIe Network Adapter

The Synology E25G30-F2 is a dual-port 25GbE SFP28 PCIe network adapter designed to bring high-speed networking to compatible Synology NAS and storage systems. With two 25GbE ports, it supports simultaneous high-throughput data transfers that are essential for environments running virtualization, large-scale file serving, or intensive backup operations. The dual-port configuration also enables link aggregation for increased bandwidth, port failover for uninterrupted connectivity, and load balancing to distribute network traffic efficiently across both interfaces.

As a purpose-built Synology accessory, the E25G30-F2 is engineered for seamless integration with supported Synology hardware running DSM 7.1.1-42962 Update 5 or later. This tight integration simplifies deployment — there are no third-party driver concerns or compatibility guesswork — but it does restrict the adapter to Synology environments exclusively. The 5-year warranty provides long-term assurance for an infrastructure component that is expected to remain in service for the life of the NAS. Users planning deployment should consult Synology's compatibility list to confirm support for their specific model and budget for SFP28 transceivers and appropriate cabling, which are not included.
