In this post I share a small PowerShell/PowerCLI script to check if VMs get backed up by Veeam B&R. If you do not run VeeamONE, it can be challenging to check if every VM that should be backed up, is really backed up. For checking this, this script should be helpful.
Slow VM snapshot deletion on NFS volumes on ESXi hosts
These days I had to troubleshoot a problem with system time within a VMware vSphere VM. During backup VM freezes for more than 30 seconds. When this happens, system time in VM also stops and resets to current time after the freeze. And this behavior causes massive problems in the application-layer. During troubleshooting we found a very slow VM snapshot deletion on NFS volumes on […]
PowerCLI script to count paths to VMFS volumes
When implementing new storages or configure existing ones it is a good idea to check paths (state and amount) to volumes. When operating a few hosts using a few datastores this can be a very time-consuming task when using the GUI. Therefore I wrote the following function.

In this blog post you can see how to configure IO limit for VM at VMDK level and how ESXi hosts executes these limits. Furthermore you will see differences between SIOC (Storage IO Control) v1 and v2 and how IO size matters.
