Upon agreement, a VO can make use of a dedicated xrootd endpoint, whose alias is reported in the public web page https://www.cnaf.infn.it/~usersupport/XrootD_SA.html.
In this case, the user can contact directly the server or otherwise a redirector. Also, the starting part of the file system path, named local root, should be known.
For instance, the server for the AMS experiment can be contacted at the 8082 port whereas 8083 is the port to contact the redirector. The local root is /storage/gpfs_ams/xrootd.
Here are some examples using xrd clients.
