E25G21-F2

 

The Synology E25G21-F2 dual-port 25GbE SFP28 network adapter is designed to support largescale deployments and high-throughput applications. It lets system administrators maximize the performance potential of compatible Synology NAS and IP-SAN.

 

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.

 

Highlights

  • High Bandwidth Two 25GbE SFP28 ports support highperformance storage applications

  • Flexible SFP28 Options Support for Optical SR, Optical LR, and DAC modules lets you optimize connectivity for distance or TCO

  • Built for Synology by Synology Built and designed for maximum performance and reliability in Synology servers
