List of VMDKs in vCenter Server 7.0 Appliance

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
  • vTSDB Service Repository for logs
  • Lifecycle for binaries (install, update and upgrade).
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.
  • You can check these disks from VAMI as shown in below screenshot.
  • We can use df -h command to retrieve disk information as shown below.
  • Another way to access this information is lsblk command on vCenter shell as shown below.

Below is the complete list of VMDKs along with their usages and mount points.
