Synology 25G PCIe 3.0 Ethernet Adapter Card | E25G21-F2
Add high-speed connectivity to your compatible Synology NAS or server with this E25G30-F2 2-Port 25G SFP28 to PCIe 3.0 Adapter Card. The two SFP28 slots work with separately purchased SR and LR transceivers, in addition to DAC alternatives, for up to 25 Gb/s fiber links to compatible devices.
This network adapter card may be installed into an available PCIe 3.0 x8 expansion slot. Built-in CPU offloading technology helps to optimize performance. This adapter is also compatible with 10 Gb/s SFP+ transceivers, allowing you to upgrade as your needs grow.
Maximize Bandwidth for Heavy-Duty Applications
The Synology E25G21-F2 dual-port 25GbE SFP28 network adapter is designed to support large-scale deployments and high-throughput applications. It lets system administrators maximize the performance potential of compatible Synology NAS and IP-SAN.1
High-performance connectivity upgrade
The E25G21-F2 adapter gives you more connectivity options with support
for SR and LR transceivers and DAC options. Dual 25GbE SFP28 ports help
remove network bandwidth limitations, while backwards compatibility
with 10GbE SFP+ equipment reduces installation and implementation
costs. CPU offloading technologies reduce network transfer overhead on
the host system's processor to boost system performance.
