You can monitor the capacity of the Virtual SAN datastore, deduplication and compression efficiency, and a breakdown of capacity usage.
About this task
The vSphere Web Client cluster Summary tab includes a summary of Virtual SAN capacity. You also can view more detailed information in the Capacity monitor.
- Navigate to the Virtual SAN cluster in the vSphere Web Client.
- Click the Monitor tab and click Virtual SAN.
- Select Capacity to view Virtual SAN capacity information.
The Capacity Overview displays the storage capacity of the Virtual SAN datastore, including used space and free space. The Used Capacity Breakdown displays the percentage of capacity used by different object types or data types. If you select Data types, Virtual SAN displays the percentage of capacity used by primary VM data, Virtual SAN overhead, and temporary overhead. If you select Object types, Virtual SAN displays the percentage of capacity used by the following object types:
VM home objects
Performance management objects
File system overhead
Deduplication and compression overhead
Other, such as user-created files, VM templates, and so on
If you enable deduplication and compression on the cluster, the Deduplication and Compression Overview displays capacity information related to that feature. When deduplication and compression are enabled, it might take several minutes for capacity updates to be reflected in the Capacity monitor as disk space is reclaimed and reallocated. For more information about deduplication and compression, see Using Deduplication and Compression.
