Thanks to Andres Moreno/SPS for providing this information:

 

 

 In the QX/QXS array logs (store.zip, storexxx.logs file) it provides midplane serial numbers for both the enclosure 0 which is typically the Raid enclosure (RBOD) with the two array controllers and enclosure 1 has the two expansion I/O Modules (JBOD)

 

Sample from one of my old logs;
