Hello Ed73,   The iDRAC is out of band so it really doesn't matter that the OS is 7.0 U3. It will work.   I would recommend to get our 7.0 U3 ISO for your upgrade:   This is Dell Customized Image of VMware ESXi 7.0U3 Dell Version: A04, Build# 19482537 [URL] ISO Image Link: [URL]  
Hello, Writing this post as i'm a bit confused regarding iDrac firmware compatibility with hypervisor We have M630 servers that we are planning to upgrade to latest ESXi version 7.0u3 On VMWare compatibility guide we can see that model is supported with 7.0u3 [IMAGE]   When checking iDrac release notes of latest supported version : [URL] Supported managed server operating systems andhypervisorsVMwareESXi 6.5 U3ESXi 6.7 U2ESXi 6.7 U3ESXi 7.0 U1   Is the document not up to date or should I stay on update 1 because of iDrac ..?
