Dual-port SFP28 network card with metal bracket

Synology Inc.

Synology Inc. E25G30-F2 dual-port 25GbE SFP28 network card

SKU CH-2GXM-ZGYPR MPN E25G30-F2

Dual-port 25 GbE SFP28 add-in card with PCIe 3.0 interface, link aggregation to 50 Gb/s and CPU offloading for Synology systems

Model E25G30-F2

  • Dual 25GbE ports deliver up to 50 Gb/s aggregated throughput
  • Link aggregation provides port failover and load balancing for resilience
  • CPU offloading support reduces host processor load during high-speed transfers
  • PCIe 3.0 interface ensures compatibility with modern Synology systems
  • SFP28 cages accept short-range, long-range transceivers and DAC cables

Dual-port 25GbE SFP28 add-in card

The Synology E25G30-F2 is a PCIe 3.0 network interface card with two SFP28 ports, each running at 25 Gb/s. It supports short-range, long-range and direct-attach copper transceivers for flexible link distances. The card is designed specifically for Synology systems.

Suited for high-throughput NAS links.

Administrators who need aggregated 50 Gb/s bandwidth with failover between two 25 GbE ports will benefit from Link Aggregation Group support. CPU offloading features help maintain host performance under load. Buyers using hardware outside the Synology ecosystem should verify driver and firmware compatibility before purchasing.

PCIe 3.0 interface

The card connects through a PCIe 3.0 slot, which determines the maximum host bus bandwidth available to the dual 25 GbE ports. Ensure the target system provides a compatible slot and sufficient lane allocation for the intended throughput.

Questions about this item

What is the maximum combined throughput when both 25GbE ports are aggregated?

The dual ports can be combined into a Link Aggregation Group to boost throughput up to 50 Gb/s.

How much heat or power draw should I expect from the E25G30-F2 during continuous operation?

The card uses a passive heatsink with no onboard fan, so it runs silently and adds minimal thermal load inside a Synology chassis.

Which transceiver or cable types are supported for the SFP28 ports on this card?

The SFP28 ports accept optical SR, optical LR transceivers and direct-attach copper cables for flexible reach options.
