The Virtual Machine Compute Optimizer (VMCO) is a Powershell script that uses the PowerCLI module to capture information about the hosts and VMS running in your vSphere environment, and reports back on whether the VMs are configured optimally based on the Host CPU and memory. It will flag a VM as “YES” if it is optimized and “NO” if it is not. For non-optimized VMs, a recommendation is made that will keep the same number of vCPUs currently configured, with the optimal number of virtual cores and sockets. Note that the VMCO will not analyze whether your VMs are configured with the correct number of vCPUs based on the VM’s workload. A more in-depth analysis tool such as VMware vRealize Operations Manager can make right-sizing determinations based on workload and actual performance. Changes in Version 2.0.0 Priority of the findings are captured Details on the findings are included Cluster information is captured to determine if Host HW is not consistent across the cluster Report if a VM spanning pNUMA nodes actually has the pNUMA exposed to the guest OS Report if advanced settings have been changed on the VM or host level to expose pNUMA to the guest OS Reports...
