Info

Please note:

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

N2WS recommends the following regarding volumes:
  1.  Volumes that are at least 10 GB in size.
  2. Volumes types should be at least Premium SSD V2.

- 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.
