No such documenttion exists.  

The closest you will come is the PCIe adapter placement guide in 
the Knolwedge Center which will tell you the prioritization 
scheme for placement of adapters irrespective of load source.  

As far as whether a specific drive bay in an EXP24S (5887) or 
the CEC needs to be set as the load source location, thankfully 
those days went bye-bye with the death of SCSI drives and 
addressing rules.
