This report calculates the number of additional VMs that your existing infrastructure can support before the resource utilization reaches the specified threshold value.
The report evaluates total capacity of your infrastructure and provides estimation of how many sample VMs of a certain profile can be added without causing the specified resource utilization threshold to be breached. Calculation of additional VM sets is based on the predicted future performance of the sample VM and the predicted virtual infrastructure capacities.
For each host, cluster and datastore included in the report, the Constraining Resource Per Each Object table displays the constraining resource, that is the resource for which the specified threshold will be breached first.
Click a host, cluster or datastore name in the Details table to drill down to in-depth forecast information for the host, cluster or datastore.
This report helps administrators to discover how many additional VMs can be deployed without affecting infrastructure performance.
Scope: defines a virtual infrastructure level and its sub-components to analyze in the report.
Business View object(s): defines Veeam ONE Business View groups to analyze in the report. The parameter options are limited to objects of the Host type.
Datastores: defines a list of datastores to analyze in the report.
VM profile: defines a VM profile that will be used as a sample for calculating the number of VM sets:
- If you choose a specific VM, the report will calculate how many similar VMs can be added.
- If you choose Average VM configuration, the report will assess average configuration across all your VMs, and calculate how many VM of this configuration can be added.
Note that VM(s) in the profile must be currently in the powered on state, and that performance data collection must be completed for the given VM(s).
Account VM CPU and memory reservations: defines whether CPU and memory reservations should be taken into account when calculating the number of VMs to be added.
CPU utilization limit (%): defines the CPU usage threshold as a percentage of total cluster CPU resources.
Memory utilization limit (%): defines the used memory threshold as a percentage of total cluster memory resources.
Max utilization per datastore (%): defines the threshold for the maximum amount of space in use on a datastore.
Min free space per datastore (GB): defines the threshold for the minimum amount of free space left on a datastore.
Datastore Read Rate (MBps): defines the threshold for read rate per second for datastores.
Datastore Write Rate (MBps): defines the threshold for write rate per second for datastores.
Max vCPU per host CPU core ratio: defines the threshold for the maximum number of vCPU cores per a single instance of the physical CPU core.
Put 1 host into maintenance mode: defines whether to simulate putting one host into maintenance mode when calculating the number of VMs to be added.
