How to monitor / report UNMAP bandwidth for particular datastore

The following command brings the correct information by using UnmapBandwidthSpec instead of UnmapGranularity.

What are the available pciSlotNumbers for RHEL8 VMs?

 

Summary

What are the available pciSlotNumbers for RHEL8 VMs?

Cause

All normally created Virtual Machines with Virtual Hardware version 7 to 19 will have the same configuration:

pciBridge0: pciBridge, 1 function

pciBridge4: pcieRootPort, 8 functions

pciBridge5: pcieRootPort, 8 functions

pciBridge6: pcieRootPort, 8 functions

pciBridge7: pcieRootPort, 8 functions

VMs with this configuration can have up to 32 PCIe devices with the slot number sequence.

 160, 192, 224, 256,

1184, 1216, 1248, 1280,

2208, 2240, 2272, 2304,

3232, 3264, 3296, 3328,

4256, 4288, 4320, 4352,

5280, 5312, 5344, 5376,

6304, 6336, 6368, 6400,

7328, 7360, 7392, 7424,

Resolution

It is possible to manually configure a VM to have a different pciBridge configuration, and therefore different pciSlotNumbers but this should only be performed in cooperation with VMware Engineering.
