Hello,
beacuse of low budget, I installed ESXi 6.7 on my DL380p G8 (2x Xe2660V2,128Gb, P420i 1Gb) without problems,
the server is a cold backup in a working system.
Prior to install ESXi I installed Server2016 and updated BIOS and controller firmware.
I simulated the disaster recovery (restore os the VMs and all) and the domain was functional!
