When the 3200 was announced, I asked this question (as we have a 3100 with two DAE shelves and would like to keep using these if possible). I was told they are not compatible, but would be interested in clarification.
Would adding existing DAEs (and replacing the base DPE with a 3200) work, and would it be supported by EMC? I'm not looking to migrate the existing data and would be happy to wipe the disk shelves. I'm interested in whether the DAEs are physically compatible and supported.
I am currently investigating this, however, just based on knowledge on the VNXe1 and 2 Series arrays. I do not think this is going to be supported. The differences between the VNXe1 Series to the VNXe2 Series are huge.
I will touch base when I find the definitive answer.
Thanks for following this up. I'd be interested in what's different between the DAE shelves between the two generations. Surely a DAE is just a SAS connection with a bunch of disks?
I have asked engineering on this topic and as of right now VNXe1 Series DAE will not be compatible with the VNXe2 Series DPEs.
