Key design considerations for ESXi

In this section, the following are the most important considerations for your VMware ESXi design:

• 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...
