Many technical consultants don't pay attention to considering the design scheme to a hostname, but the hostname is very important for operational management. So you should name the host according to the following rules.
Use simple, descriptive, and easy-to-understand hostnames. A standardized naming convention results in easier management, troubleshooting, and use, all of which reduce operational expenses. An example is esxi-<locationcode-##>.<domain.name>, esxi-shanghai02.test.com
