Will a DAE from a VNX5300 work with a VNX2 system VNX5400/5600...?
I am retiring some VNX5300s, and I also have some VNX2 arrays that are not 'fully loaded'. I know that the disks are largely interchangable between the two families, but I haven't found any documentation that suggests that either a controller swap, or an upgrade using the older DAEs is possible.
I would like to know if I can use one or more DAEs from the 5300 to augment the disk count on a VNX2.
If they are not compatible I would *guess* it would come down to something about eh LCC modules or something similar, as both are 6Gb SAS enclosures with physically identical backplanes.

From what I can find the LCC's for the 15 and 25 slot DAE's are the same for VNX1 an VNX2.
The 25 disk DAE is the same part number for VNX1 and VNX2.
It looks like the 15 disk DAE is the same also, but the part numbers are slightly off.

It appears that it should be possible to use the DAE's from the VNX1 to the VNX2. For the disks in the VNX1, you would need to check the Drive and Flare Matrices

keep in mind that if your system in under a maintenance contract then you should check with your service provider

Glen. Thanks, that is what I was thinking.
I know that many/most of my drives are part numbers that are good for either family; what I was figuring was that once the the DAEs were installed they would get/need new LCC/Power Supply code, and that USM would help me with that.
Once that was complete I'd start installing the drives.
I've added DAEs a number of times, and it isn't really difficult. Removing them is a bit quirkier; sometimes it requires a round of controller reboots (one at a time) to get the array to accept the loss...gracefully...and return to looking healthy.
Naturally I would pull a configuration report for my service provider and true-up maintenance where needed.
Thanks for your input; this is speculative at the moment, but if/when I actually do it I'll update the thread with a report on the results.
