Simply connect the Twin10G SFP+ adapter to your computer via the included 40Gbps Thunderbolt cable, download and install a driver, install SFP+ module(s) (sold separately), connect the adapter to the network switch or directly to 10GbE-enabled storage, and configure the adapter’s settings through the macOS Network control panel, Windows Device Manager, or Linux command line (or graphical utility).
Intelligent Operation
The Twin10G SFP+ adapter’s high throughput performance and low host-CPU utilization are attained through functions such as flow control, 64-bit address support for systems using more than 4GB of physical memory; and stateless offloads such as TCP, UDP and IPv4 checksum offloading. These operations enable your computer to perform better while large files transfers or high I/O operations take place. This Sonnet adapter’s dual 10GbE connections support transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fail. Windows and Linux also support link aggregation (teaming) for increased throughput!
