Facebook user experience. An FNA cluster consists of a Top-of-Rack (ToR) switch and from two to twenty servers. The illustrations in this guide will show a typical 4-server cache deployment, so please consider these illustrations as an example and follow the instructions taking into account the number of servers actually deployed.

Uplink capacity is selected for every order, either with 10G or 100G ports. Optical transceivers will be sent according to the port type selected. Facebook provides transceivers only for the FNA, while optics for the ISP devices must be provided by the ISP. For 10g uplink, by default FB will send as many SFP+ as servers in the order.
Page 6 LC-LC, LC-SC, (Lucent Connector – Subscriber Connector), etc. Optics for the ISP devices must be provided by the ISP. The FNA accepts 10G SR and LR, and 100G SR4 and LR4 optical transceivers. Facebook provides the most optimal optical transceiver type, corresponding to the type you currently use to connect your routers.
