Hello Piotr, CX4-120 has only 1 Backend Bus. It's 2 BE ports per array , 1 per SP. Can you please point what document state otherwise so it can be corrected ?  Thanks,
Hello All,  I would like to raise a question about number of BUSes on CX4-120, I've found two documents at support.emc.com where one says that theres is one BUS, and second doc says that there are two BUS for DAEs.  Which one tells the truth?  Cheers, Piotr
