Up to 2000 instances –

Standard_D8s_v3, Standard_D8ds_v4, Standard_F8s_v2, Standard_E8s_v3 1, Standard_E8ds_v4, Standard_E8s_v3, Standard_D8ds_v5

Up to 4000 instances –

Standard_D16s_v3, Standard_D16ds_v4, Standard_F16s_v2, Standard_E32s_v3 , Standard_E16ds_v4, Standard_E16s_v3, Standard_D16ds_v5

Over 4000 instances –

Please move additional instances to a new CPM Server


Please note:

- CPM is more IO-intensive than CPU-intensive, improving IO performance will usually gain better results than improving CPU performance.

- The above recommendations are based on the following assumptions:

  1. Instances have 3 volumes on average.
  2. No more than 20% of VM's have Agents performing VSS/scripts.
  3. No more than 20% of VM's are being backed up simultaneously (within 60 minutes from each other).
- Exceeding these assumptions may require larger instance sizes.

- For over 200 VM's or 600 volumes, you may need to increase IOPS - we recommend that you add another 500 IOPS per each 100 VM's or 300 volumes above this limit.
