The fact is, great experience with a powerful set of tools will make you a force to be reckoned with. This chapter will cover various tools that you can use for monitoring utilization, measuring performance, and simulating load. In this chapter we look at: ◆ Capacity planning tools ◆ Performance analysis tools ◆ Performance benchmarking tools ◆ Performance simulation tools Capacity Planning Tools Capacity planning is multifaceted, comprising planning for what to provision in your environment, analyzing what already exists as your environment grows, and scaling your capacity to meet changing demands.
This is a smart question to ask, and one that VMware prepared for when it revealed the HA, or High Availability, feature of VMware Infrastructure 3. A virtual infrastructure is managed by vCenter, which is aware of all of the hosts that are in its control and all the VMs that are on those hosts. vCenter installs and configures HA, but at that point, the ESXi hosts monitor heartbeats and initiate failovers and VM startup. This is fundamentally important to understand because vCenter can be one of the VMs that has gone down in an outage and HA will still function, providing a master HA host, aka failover coordinator, is still available.
Keeping your CPU family the same will enable you to have VMs vMotion throughout the cluster without any complication or efforts on your part. By reusing older hardware, which may require EVC, you may be introducing more problems and need to troubleshoot more issues in your environment than if you had a more uniform virtual infrastructure. There is by no means anything wrong with reusing older hardware; you just need to consider whether the benefit of repurposing outweighs that of replacing it in power, cooling, performance, and space.
