Host support for SCSI thin provisioning


To leverage the benefits of SCSI thin provisioning, it must be supported by your host. SCSI thin provisioning uses the Logical Block Provisioning feature as defined in the SCSI SBC-3 standard. Only hosts that support this standard can use SCSI thin provisioning in ONTAP.

The following hosts currently support SCSI thin provisioning when you enable space allocation:

  • VMware ESX 5.0 and later

  • Red Hat Enterprise Linux 6.2 and later

  • Citrix XenServer 6.5 and later

  • Microsoft Windows 2012

  • Microsoft Windows 2016

When you enable the space allocation functionality in ONTAP, you turn on the following SCSI thin provisioning features:

  • Unmapping and reporting space usage for space reclamation

  • Reporting resource exhaustion errors
