Correct that is what the ISO I gave does, but DevMgr is correct as well. The R510 is a release from the 11th Generation, so the Vmware 5.5 ISO should have those drivers, but the Dell 5.5 ISO will have those as well as the 12th generation servers models too. So with the Vmware 5.5 you can do 11th generation and older. With the Dell ISO you can do all of the Dell servers (that support ESXi) including 12th generation.  So both will actually work, but I would personally go with the Dell ISO as it is specific to the products. 
Hello, I have two R510 servers running Esxi 5.1.I have already upgraded the vCenter server to 5.5 and am ready to upgrade the network and storage drivers and firmware on the host. Is this image VMware-VMvisor-Installer-5.5.0-1746974.x86_64-Dell_Customized_A04.iso the one I need? It says "VMware ESXi 5.5 Image" on the title... Thanks, Avital
upgrade from ESXi 5.1 to ESXi 5.5
