Hi vsan Team,

could someone suggest me on the folowing .

below vm is configured on vsan datastore with default storage policy .

also there are three objects vmnamespace,vdisk,vmswap .

i am seing 58.10 GB is the the provisioned space .

since vsan default policy is unisng raid 1 as fault tolerence .

i was expecting 2 times the size of vmdk+plus some overhead as the provisioned size (ie close to 112GB) .

can someone expain above.

Hello jvm2016​

Default SP is thin-provisioned and FTT=1 with FTM=RAID1, so a vmdk used space will be 2x the used space, not the provisioned space.

Validate you get similar values in the UI e.g. on the summary tab of the VM, the 'Storage Usage' should be the cumulative value of all vmdk disks (including replicase) + .vswp + any usage in namespace.

thnaks bob .as yu mentioned used space is cumullative so it has already taken into account the  space for replica and overhead .
