In vCenter Server Appliance 7.0, there are 16 VMDKs now. In vCenter Server Appliance 6.7 version it was 13 disks. Additional 3 new disks in this release are as follow:
- vTSDB Service Repository for stats

There are multiple ways in which we can access information about disks. Below are some of the examples.
- We can check usage from vimtop about disks, however vimtop does not show all disks.
- Complete list of disks can be seen in Appliance VM edit settings as well.
