Synology E25G21-F2 Dual 25G SFP+ Port PCIe 3.0 Adapter

Synology E25G21-F2 Dual 25G SFP+ Port PCIe 3.0 Adapter Boost your data throughput to support bandwidth-heavy workflows, such as high-resolution videos, with the E25G21-F2 Dual 25G SFP+ Port PCIe 3.0 Adapter from Synology. Designed specially for select Synology NAS systems, this network adapter installs into an available PCIe 3.0 x8 slot, adding two 25 Gigabit SFP28 ports. These ports also support optical SR, optical LR, and DAC transceiver modules to optimize connectivity. You can also combine both ports using link aggregation for higher simultaneous throughput, port failover, and load balancing. Additionally, built-in CPU offloading technologies help to reduce the host system’s network transfer overhead to further enhance performance. Both low and full-height brackets are included.
