Discrepancy between the free storage capacity confirmed on the vSphere Client and the PureStorage management dashboard.

Products

• VMware vSphere ESXi

Issue/Introduction

VMFS does not report the same used capacity as the FlashArray for the underlying volume.

Environment

ESXi 7.0
ESXi 8.0

Resolution

The "used" value for a VMFS datastore displayed in the vSphere Client is an independent metric from the "volume usage" reported by PureStorage. It is expected that the two figures may differ.
