This topic discusses the limitations of Virtual SAN.

When working with Virtual SAN, consider the following limitations:

  • Virtual SAN does not support hosts participating in multiple Virtual SAN clusters. However, a Virtual SAN host can access other external storage resources, but at any point, can participate in one Virtual SAN cluster.

  • Virtual SAN does not support vSphere DPM and Storage I/O Control.

  • Virtual SAN does not support SCSI reservations.

  • Virtual SAN does not support RDM, VMFS, diagnostic partition, and other device access features.
