Can we connect multiple File Gateways to one FSx ?

Hello,

Yes, you can use multiple FSx File Gateways and attach the single FSx Windows file server to multiple gateways. However, please note this would be a multiple writer scenario which could cause issues if a second writer (Gateway B) modifies written files than the specified gateway (Gateway A). To avoid running into issues with multiple writers, we recommend using dedicated folders for each FSx File Gateway without any overlap on the FSx file server.
