Consider using VMware Capacity Planner to investigate the performance and usage of prevailing servers; this will help you to identity the requirements for planning.

Consider eliminating inconsistency and achieving a controllable and manageable infrastructure by homogenizing the physical alignment of the ESXi hosts.

Never design ESXi without a remote management console such as DRAC and ILO.

Ensure that syslog is properly set up for your virtual infrastructure and log files are offloaded to non-virtual infrastructures.

Consult your server vendor on proper memory DIMM size, placement, and type to get optimal performance. While other configurations may work, they can greatly impact memory performance.

Ensure you choose the right hardware for the ESXi host, while aligning the functional requirements with a workload that has a baseline and performance that has a benchmark...
