Recently, I was dealing with an HCI cluster and I needed to see how the slabs (or extents, if you prefer) are placed on each disk. Since there is no such direct PowerShell command to visualize this information, I ended up writing a small function that serves this purpose. The function performs some queries on the virtual disk to find the slubs, calculate the statistics and correlate with the hosts that hold each disk. In the end, it groups the results and returns them in a single table.
