This is the Relative Name (RN) of a storage connection definition object: the single naming component that, combined with its parent's DN, distinguishes this storage connection definition from any sibling instances under the same parent. Admins rarely read the RN by itself, but UCS Manager and management tools use it to build and parse the full DN path so each instance of a storage connectivity definition specifying how UCS connects to a SAN, including its Fibre Channel zoning type and operational state can be addressed uniquely. For instance, when a SAN fabric has several storage connection definitions attached, the RN is the piece that differs between their otherwise-identical parent DNs, letting a script enumerate all of them.
