Product Description
The Synology E25G30-F2 is a dual-port 25GbE SFP28 add-in card developed for compatible Synology systems.
It uses a PCIe 3.0 x8 host interface and supports either 25Gbps or 10Gbps network operation.
Its two ports can be combined into a Link Aggregation Group to provide aggregate throughput of up to 50Gbps while supporting port failover and load balancing.
The E25G30-F2 supports short-range optical, long-range optical and direct attach copper connectivity.
Network processing technologies include TCP Segmentation Offload, Receive Side Scaling, Generic Segmentation Offload, TCP/UDP checksum offload, Transmit Side Scaling, SR-IOV and Large Receive Offload.
Both network ports must operate at the same link speed. Mixed 25GbE and 10GbE operation across the two ports is not supported.

Network Configuration Note
Both E25G30-F2 network ports must be configured at the same link speed.
Mixed 25GbE and 10GbE operation across the two ports is not supported.
Link Aggregation can increase aggregate network throughput across multiple connections but does not increase the maximum speed of an individual transfer.
