Hi,

In my company, we do have a "booking" process. The only way we found to follow these requirement is to manage them out of vCenter.

In fact, we use 2 differents sources :

1. Health check report, to follow actual resources demands
2. An excel file, where every request that "may soon or not" be activated is listed

Using these 2 files, we made a small program that is able to tell us some key informations:

1. How many vCPU are actually declared on the hosts and the ratio with the physical cores
2. Same for vRAM and RAM
3. How many vCPU will be declared if every request are activated
4. Same for vRAM and RAM

This enables us to know when new hosts are required (we do not require project to fund them).

We also combined this analysis with vCenter Operations Manager dashboards on every clusters to know the actual resource demand (instead of the "declared" part as stated above).

Hope it helps.

Ludovic
