Connectivity Boost for Bandwidth-Heavy Workloads
The Synology E10G21-F2 dual-port 10GbE SFP+ network adapter is designed to boost the throughput of compatible Synology systems. Ideal for businesses looking to support growing numbers of users or more intensive workloads with increased bandwidth for storage operations.
Cost-effective upgrade for Synology NAS and IP-SAN
The E10G21-F2 adapter gives you more connectivity options with support for SR and LR transceivers and DAC options. Dual 10GbE ports help alleviate network bandwidth limitations and support Link Aggregation (network bonding) for increased resiliency in the face of network disruptions. CPU offloading technologies reduce network transfer overhead on the host system’s processor to boost system performance.
High Bandwidth
Two 10GbE ports support high-performance storage applications.
Flexible SFP+ Options
Supports Optical SR, Optical LR, and DAC modules to optimize connectivity for distance or TCO.
Built for Synology by Synology
Built and designed for maximum performance and reliability in Synology servers.
5-year warranty
At Synology, we are committed to product innovation and quality. Synology guarantees a robust and reliable data management experience with a 5-year limited warranty, providing responsive technical support and hardware replacement services to maximize your return on investment.
