The VNXe supports only one backend port (SAS port 0) at this time.  Please see the "Installing an Optional Disk-Array Enclosure (DAE)" manual for expansion cable instructions.
Hi. I have VNXe 3100 with software version 2.0.2.12987. On DPE and DAE installed 24 NL SAS disks. I need to connect additional DAE with 6 SAS disks to the SAS port 1.  But can't find any docs about this. Please help.  Thanks, Zaour.
