I did a search on our internal tools and outside of Dell's internal resources just to be sure, but as far as I know, there are only 2.5 inch carriers and 3.5 in carriers (which can use an adapter to hold a 2.5 in drive). There arent nvme specific carriers for the T630/R630, they are the same carrier. The 14G and later carriers definitely dont fit any 13G or before systems. There are multiple part numbers of the 2.5 inch 13G carriers, minor changes to them, but all will work just fine in a T630, except the carriers for the 13G blades that are for the M1000e chassis, which are much shorter than the T630/R630 drive carriers. #Iwork4Dell 
Hello! Anyone knows what the Dell p/n is for the 2.5" U.2 NVMe drives that go into the 4x NVMe bay in a PowerEdge T630? I believe they are somewhat different from the 2.5" SAS/SATA drive sleds (0G176J) that have been common since the PE 11G days (IIRC the NVMe ones are silver not bronze, and there may be other differences as well)? They aren't the same as the new style sleds for the 14G servers, are they? Thanks!
PE T630: what is the P/N for the 2.5" U.2 NVMe drive sled?
