Measures reported by VsanOverviewTest

A VMware vCenter server can manage more than one vSAN cluster. A single vSAN cluster consists of any number of physical server hosts from two to 64. Additional hosts can easily be added to an existing cluster in a matter of minutes for additional compute and storage capacity. vSAN aggregates all local capacity devices into a single datastore shared by all hosts in the vSAN cluster. The datastore can be expanded by adding capacity devices or hosts with capacity devices to the cluster.

To plan the needs of the virtual infrastructure and to determine whether/not additional capacity devices need to be added to the vSAN cluster to handle the current and anticipated load, administrators should keep track on the available resources on the vSAN clusters that are managed by the VMware vCenter server. This can be easily achieved using the vSAN Overview test. This test reports the count of datastores, vSAN clusters and hosts available in the VMware vCenter server.

Note:

This test is applicable only for the vSAN enabled clusters in the VMware vCenter server.

Outputs of the test : One set of results for VMware vCenter server that is being monitored.

The measures made by this test are as follows:

Numeric Value Measure Value
0 FLASH
1 HDD

Note:

By default, this measure reports the Measure Values listed in the table above. In the graph of this measure however, the drive type of an physical disk is indicated by its corresponding numeric equivalents only.
No_of_datastores Indicates the total capacity of this disk. GB  
No_of_clusters Indicates the amount of space utilized on this disk. GB  
No_of_hosts Indicates the percentage of space utilized on this disk. Percentage
