How to run VAAI UNMAP and return capacity to Element
Applies to
- NetApp Element software
- ESXi 5.5, 6.0 & 6.5
- VMware Virtual Machine File System (VMFS) 5
- VCP 4.x
Description
- UNMAP allows the ESXi host to inform the storage array that files or VMs have been moved or deleted from a Thin-Provisioned VMFS datastore
- This allows Element software to correctly release unused blockspace and reclaim capacity
- UNMAP is beneficial to use when vCenter is reporting less used data than Element software is using
