The methodology previously presented for VMware capacity/performance analysis is extended to I/O analysis (memory analysis, 2013, and CPU analysis, 2019). The methodology demonstrates a holistic approach which analyzes groups of metrics from each layer of the virtualization, i.e. ESX datastore, VM, the VM’s operating system (Linux or Windows), and the application in order to determine if the application I/O demand has changed or downgraded performance from the storage appliance has occurred.
