Hello johnnydotexe We haven't validated the 860 for any version of VMware. I just searched and found posts of customers installing up to ESXi 5.0. There is not much difference between 5.0 and the latest 5.5 regarding hardware compatibility, so I don't see a reason why you can't install 5.5. I would suggest using our custom ISO. Even though we don't support VMware on the 860 a lot of drivers are used across multiple products, so there may be drivers for the 860 hardware available on our disc. Since this is not a validated configuration I would advise you to be aware there will likely be oddities, and it is not advisable to run unsupported configurations in a production environment. Thanks
Looking to switch over from my current VM setup to a baremetal VM setup and I'm trying to figure out the latest version of ESXi that will work on my PE 860, and if there is anything in particular I need to do to make it work.I found the Dell custom ESXi files but I don't know if I should use those versions or just stick to a version from VMware.Thanks.ETA:  This PE 860 has the 1 x 2.4GHz Xeon Dual Core and I am only running one SATA HDD in it on SATA_0, may add another in the neat future.
Compatible version of ESXi for PowerEdge 860?
