Host Agent or the Navisphere Server Utility to
register the server NICs or HBAs with the storage system. Depending on your

You cannot install both applications on the same server; however, you can install
them on different servers attached to the same storage system. Table 1 describes the
differences between the Host Agent and the Server Utility.
