Yes, it is the same file. Same hash and both show under compatible systems. 
I will be installing ESXi 6.0 update 2 onto 3 new M630 servers.  I used the following ISO to install my m420s: VMware-VMvisor-Installer-6.0.0.update02-3620759.x86_64-Dell_Customized-A02.iso Will this ISO work for my m630s as well? These machines have been ordered and received by a re-seller and they have not given me the service tags.  Therefore I cannot add them to my products and see the downloads available.  This may become a frequent problem for me as I am in charge of deployment.  Thank you in advance for the answer to my question.
Difference between ESXi ISO for M420 and M630. Is it the same ISO?
