The Synology E25G21-F2 is a dual-port 25GbE network interface card designed for compatible Synology systems. It provides high-speed connectivity for environments with demanding data throughput, such as production studios and research labs. Each of the two ports uses SFP28 connectors to support 25Gbps link speeds over fiber-optic cabling. By increasing network bandwidth beyond standard 10GbE options, the adapter reduces latency during intensive tasks, such as concurrent file transfers and virtualization traffic.
The circuit board and mounting hardware feature a silver, black, and blue finish. Once installed, administrators can monitor link status and performance metrics via the primary interface. This adapter allows for dedicated storage traffic for virtual machines without affecting general network access. It is compatible only with specific Synology NAS models; please verify compatibility with your host device to ensure proper installation.
Key Features:- 168 mm width fits standard internal mounting requirements.
- 69 mm depth ensures it fits within standard expansion bays.
- 17.3 mm height allows for low-profile installation in compact NAS chassis.
- Designed as a high-performance network adapter for IT infrastructure.
- Supports rapid transfer of large data volumes across a local network.
- Dual independent links enable path redundancy or increased aggregate throughput.
