An administration host can be any workstation that is either an NFS or a CIFS client on the network.
Reasons to designate a workstation as an administrative host
You designate a workstation as an administration host to limit access to the storage system's root file system, to provide a text editor to edit configuration files, or to provide the ability to administer a storage system remotely.
Administration host privileges
After the setup procedure is completed, the storage system grants root permissions to the administration host.
