For an XtremIO cluster to use FTPS (File Transfer Protocol Secure) for the Connect Home feature, the firewall ports that need to be opened are 989 and 990. These ports are used for data connections and control connections under implicit security for FTPS1.
When using explicit security, FTPS can also use port 21, but since the question specifies FTPS for Connect Home, which typically uses implicit security, the correct ports are 989 for data transmission and 990 for the control connection1. It's important to ensure these ports are open to allow secure file transfer capabilities for the XtremIO cluster.
