Products

• VMware vSAN

Issue/Introduction

• In vCenter UI, vSAN Datastore > Configure tab shows the Capacity utilization of the vSAN cluster, including the provisioned space.

Environment

Resolution

Provisioned Space is the total size allocated to the VMs.

In vSAN Cluster, the provisioned space also include the space consumed by the RAID in the Storage policy used.

RAID-5 -- 1.33x
RAID-6 -- 1.5x

Provisioned space in the cluster will be increased if we add more VMs or add disks to existing VMs.
