Replying to mark TOTAL OF ALL PREVIOUS POSTS IN THIS DISCUSSION as the SOLUTION. But please continue to post any questions/comments.
We wanted to provide a point of clarification for the version of IDPA (2.4) which recently released on 5/21/19. This software version only applies to the version of the DP4400 (also released on 5/21), which now has an entry capacity starting at 8TB. The IDPA software stack delivers the same functionality as its predecessor, IDPA 2.3, but now with a new Appliance Configuration Manager (ACM) to handle the lower starting capacity for this version of the DP4400 and a licensing schema that jumps from 8TB to 24 TB in 4TB increments.  So, the net is if you are a current owner of the DP4400 shipped out prior to 5/21/19, IDPA v2.4 would not apply to your product. There will be a new software release later in 2019 that will apply to all DP4400 products. thank you, Dell EMC Support Team
