The correct answer is A. There is a network problem with the Virtual SAN vmkernel ports. A Virtual SAN datastore showing only 100GB out of an expected 300GB typically indicates a network problem preventing the other two hosts from contributing their storage.
Question
After configuring a Virtual SAN cluster, an administrator using the vSphere Web Client notices that the Virtual SAN datastore is smaller than expected. The cluster contains:
-Three ESXi hosts -Each host has one 10GB SDD -Each host has one 100GB HDD Why would the Virtual SAN datastore show as 100GB instead of 300GB?
Options
- AThere is a network problem with the Virtual SAN vmkernel ports.
- BThe Virtual SAN VASA provider is disabled.
- CvSphere High Availability is enabled on the Virtual SAN cluster.
- DThe Virtual SAN cluster must be managed using the vSphere Web Client.

Why each option
A Virtual SAN datastore showing only 100GB out of an expected 300GB typically indicates a network problem preventing the other two hosts from contributing their storage.
Virtual SAN requires fully functional vmkernel network ports with VSAN traffic enabled on all participating hosts. A network misconfiguration or connectivity failure prevents one or more hosts from joining the VSAN cluster, meaning their disks are not included in the datastore - resulting in only one host's 100GB HDD being visible instead of all three hosts' combined 300GB.
The VASA provider affects storage policy reporting and VM storage profiles, but disabling it does not reduce the usable capacity shown for the VSAN datastore.
Enabling vSphere High Availability on a VSAN cluster does not reduce datastore capacity; HA and VSAN coexist and HA does not consume or hide raw storage.
The management interface used (Web Client vs. other tools) has no effect on the physical capacity contributed to or displayed by a VSAN datastore.
