ESXi Tools

Not by default, though tools are available. The Dell custom image just includes drivers. For hardware monitoring, OpenManage Server Administrator is what you would want to look at. There is also OpenManage Enterprise that can aid in management of larger device volumes. There is also PERCCLI for interfacing with the RAID controller from the OS. 

It doesn't look like we have a 6.7 image for the Xr2, based on the support page, but if it's up and running, you should be good. To use OMSA, you need the software agent installed on the host, and then another instance installed in either a Linux (with desktop) or Windows environment. You can use this to manage the VMware server by selecting the option to manage a remote node, then entering the IP address.

You can also find all your manuals on the support page for the XR2: https://www.dell.com/support/home/us/product-support/product/oth-r440-xr/manuals
