What is ESXi?
In simple term (Not Technical), ESXi is an Operating system just like Microsoft Windows or Linux but it allows you to create Mini Servers on a Physical Host.
“VMware ESXi is a purpose-built bare-metal hypervisor that installs directly onto a physical server. With direct access to and control of underlying resources, ESXi is more efficient than hosted architectures and can effectively partition hardware to increase consolidation ratios and cut costs for our customers.”
“VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.”

- ILO or iDRAC
- VNC/KVM or console access is working
- Virtual Media’s can be attached via Console
Server: CISCO UCS B200M4
CPU: Intel Xeon E5-2699 v4 @2.40 GHz

d. DNS Suffix:
e. Disable IPv6:
19) Disabling IPv6 will initiate server reboot. Wait for the server to be rebooted.
Once the server is rebooted you can add it in vCenter to manage or browse the host IP to manage is using Host manager.
