This topic discusses the limitations of vSAN.

When working with vSAN, consider the following limitations:

  • vSAN does not support hosts participating in multiple vSAN clusters. However, a vSAN host can access other external storage resources that are shared across clusters.

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

  • vSAN does not support SCSI reservations.

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