Software: vSAN data encryption; HyTrust DataControl (validated)
Hardware: vSAN does no longer support self-encrypting drives (SEDs).
Software: vSAN supports native data-at-rest encryption of the vSAN datastore. When encryption is enabled, vSAN performs a rolling reformat of every disk group in the cluster. vSAN encryption requires a trusted connection between vCenter Server and a key management server (KMS). The KMS must support the Key Management Interoperability Protocol (KMIP) 1.1 standard. vSAN native data-at-rest encryption is only available in the Enterprise edition.
vSAN 6.7 encryption has been validated for the Federal Information Processing Standard (FIPS) 140-2 Level 1.
VMware has also validated the interoperability of HyTrust DataControl software encryption with its vSAN platform.
