An HBA is a physical card. Think of it as an "optical SCSI card".
Thus, there won't be any PostgreSQL docs for it.
Tablespaces let you specify what directory you want to put an object
in. This is useful for large systems with multiple RAID sets on
different SCSI busses. It's also useful for smaller systems where
you want named subdirectories for different groups of data.

Is "common sense" really valid?
For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
