SYNOLOGY E25g30-f2 - Dual Port 25gbe Sfp28 Add-in Card For Synology Systems

The Synology E25G30-F2 is an internal wired network card that provides 25GbE connectivity for modern enterprise networks. Installed via a PCI Express slot, the card supports a maximum data transfer rate of 3125 Mbit/s and complies with IEEE 802.3ad, IEEE 802.3ae and IEEE 802.3by standards. Available in a blue housing, it is designed for systems requiring higher throughput and reliable wired Ethernet connections.

Advantages

The card supports flexible SFP28 transceiver options including short-range and long-range modules as well as direct-attach copper (DAC) cables, enabling adaptable link choices. Two 25GbE ports can be combined into a Link Aggregation Group to increase throughput up to 50 Gb/s while providing port failover and load balancing. The device also supports CPU offloading and load balancing technologies to improve overall system performance. Synology provides a 5-year limited warranty covering technical support and hardware replacement.
