SFP28 network card with 2 25GbE ports for Synology storage systems. Two 25GbE ports for high-performance storage applications. Supports SR and LR transceivers as well as DAC options. Enables higher simultaneous throughput, port failover, and load balancing. Specifically designed for use with Synology systems. Host bus interface: PCIe 3.0 x8. Dimensions (H x W x D): 68.9 x 168 x 17.3 mm. Expand your connectivity options with the E25G30-F2 adapter, which supports SR and LR transceivers as well as DAC alternatives. Two 25GbE SFP28 ports efficiently eliminate bandwidth limitations, while backward compatibility with 10GbE SFP devices reduces implementation costs. Noticeable performance improvements thanks to CPU offloading technologies that relieve the host system's processor during network traffic. Flexible SFP28 options. Support for short-range and long-range transceivers as well as DAC options for flexible connectivity possibilities. Link Aggregation: The two 25GbE ports can be combined with Link Aggregation to increase throughput up to 50 Gb/s while providing port failover and load balancing. CPU offloading and load balancing: The support for CPU offloading and load balancing technologies enables optimal system performance.
