Host Port

A physical connection on the host adapter that resides within a host . When the host adapter only has one physical connection (host port), the terms host port and host adapter are synonymous.

The host ports are automatically detected by the storage management software once the host operating system recognizes the host port. A host port is the actual physical connection that allows a host to gain access to the logical drives in the storage subsystem. If you want to define specific logical drive-to-LUN mappings for a particular host and create storage partitions, you must define its associated host ports.
