- ELM is supported in VxRail 7.x clusters only. ELM is not supported in earlier releases of VxRail.
- ELM is not supported between a customer-supplied vCenter and a VxRail-supplied vCenter. ELM is only supported between VxRail-supplied vCenters.
- Up to 15 VxRail-supplied vCenter instances can be linked.
- VxRail clusters running v7.0.100 or later can enable ELM during the VxRail initial build process.
- VxRail clusters running v7.0.200 or later can enable ELM between VxRail-managed vCenter Servers as a Day 2 operation after VxRail initial build is completed.
- See the vCenter Enhanced Linked Mode Prerequisites section of the VMware vCenter Installation Guide for more detailed information.

- vSAN encryption is a vSphere feature to encrypt ‘data at rest’ on the vSAN datastore.
- VxRail-supplied vCenter does not support vSAN encryption in versions earlier than 4.5.200.

- vSphere also supports encryption at the virtual machine layer as an option to vSAN encryption.
- Starting with VxRail 7.0.200, the native key provider that is embedded with vCenter can be used for encryption purposes.
