The Cluster Capacity Report indicates how many more VM workloads can be added to clusters based on CPU, memory and storage resources, indicating where and how the clusters are constrained for growth. This report also provide details about each host contained in a cluster.
|Embotics® vCommander® takes VMware's HA Reserve and the Additional Reserve settings into account when performing a capacity check. See About capacity reserved for high availability failover and Setting the default reserved capacity for performance and growth for more information.|
Use the Cluster Capacity Report to:
•view the remaining capacity available for deploying additional VM workloads to clusters in a specific location
•view which resources (CPU, memory or storage) are constraining the addition of VM workloads in a cluster
•help you determine when you will need more CPU, memory or storage based on trends
•help you determine when a cluster is becoming constrained, based on a threshold that you set
For more information on capacity calculations, see Managing Host and Cluster Capacity.
For general information about running reports, see Running and Scheduling Reports.
1.Select one of the two available reporting methods from the Calculate Using drop-down menu: Average weekly CPU & Memory values or Peak weekly CPU & Memory values (for more information about average and peak values, see Managing Host and Cluster Capacity).
2.Expand the tree in the Location drop-down menu to select the location of the cluster(s).
3.Select a period of time from the Period drop-down menu. See Using Date Filters for Reporting and Searching for details on each option.
4.To set a threshold to help you determine when your clusters are becoming constrained, select a value from the Threshold drop-down menu.
5.Select "Yes" or "No" from the Trend drop-down menu depending on whether or not you want projected trends to be displayed.
6.Enter a comment if desired.
The Cluster Capacity Report displays a Capacity Summary chart for the location(s) you selected. This chart indicates the capacity remaining now and the projected capacity available in the future for all clusters in the location you selected. If the chart is trending downward, your environment is running out of space to deploy additional VM workloads. If the chart is trending upward, your environment has the capacity to handle additional VM workloads.
The following sample report was generated for two clusters. It displays average weekly CPU and memory values for a period of 30 days.
Cluster Capacity Report - Part 1
For each individual cluster in the location you selected, the Cluster Capacity Report displays four charts as shown in part 2 of the example:
•VM Capacity Remaining that displays the remaining capacity for VM workloads
•CPU Capacity that displays capacity based on CPU constraints, assuming that memory and storage are unlimited
•Memory Capacity that displays capacity based on memory constraints, assuming that CPU and storage are unlimited
•Storage Capacity that displays storage constraints, assuming that CPU and memory capacity are unlimited
Each chart (with the exception of VM Capacity Remaining) displays the maximum available capacity for each resource using a red line and your actual usage using a blue line. A yellow line indicates the threshold you configured.
The final section of the report for each cluster lists details about the constraining resources for the Compute Capacity and about the available storage.
