Boost your data throughput to support bandwidth-heavy workflows such as high-resolution videos with the E10G21-F2 Dual Port 10G SFP+ PCIe 3.0 Ethernet Adapter from Synology. Designed especially for select Synology NAS systems, this network adapter installs into an available PCIe 3.0 x8 slot, adding two 10 Gigabit SFP+ ports. These ports 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.2.3-25426 or later is required.
