As shown in Figure 10, VDC EKM mapping assigns a subset of a cluster member server to a VDC so that nodes in the VDC can use them to access cryptographic keys.
For more details about how to configure the EKM mapping, see the ECS Administration Guide.
Note: At least two key servers should be added before proceeding to VDC EKM Mapping. Activation is not enabled without a minimum of two key servers. Once a key server is mapped, delete option is disabled. You must remove EKM mapping to delete the key server.
