vSphere 6.5 Virtual Machine Encryption Performance
VMware vSphere virtual machine encryption (VM encryption) is a feature introduced in vSphere 6.5 to enable the encryption of virtual machines. VM encryption provides security to VMDK data by encrypting I/Os from a virtual machine (which has the VM encryption feature enabled) before it gets stored in the VMDK.
