The Synology E25G30-F2 in depth

25GbE for Synology systems

The E25G30-F2 adds two 25GbE SFP28 ports to compatible Synology systems through a PCIe 3.0 x8 slot, removing network bandwidth limits for demanding storage workloads. It works with SR and LR transceivers or DAC cables, and backward compatibility with 10GbE SFP+ gear means you can move to 25GbE at your own pace.

Offloads that free up the CPU

Checksum, segmentation and receive offloads (TSO, GSO, LRO), receive and transmit side scaling and SR-IOV reduce network overhead on the host processor, while IEEE 802.3ad link aggregation adds failover and load balancing across both ports.
