| Add-on Card |
| Add-on Card | The Supermicro is one of the most feature rich 25GbE controllers in the market. Based on the Mellanox® with features such as VXLAN and NVGRE; it provides flexible connectivity for different networking requirements. It is compatible with 10GbE networks and offers the most cost effective upgrades from 10GbE to 25GbE in Data Center and Cloud deployments. The also supports an additional 2 ports of 10GbE RJ45 connectivity, based on the controller, providing NC-SI for Remote Management. This versatile 25GbE controller is an excellent choice to enhance data center network connectivity when high speed throughput is required. To order, contact your distributor. This product is only available through Supermicro. |
