FIGURE 274 Encryption Group Properties dialog box - HA Clusters tab HA clusters are groups of encryption engines that provide high availability features. If one of the engines in the group fails or becomes unreachable, the other cluster member takes over the encryption and decryption tasks of the failed encryption engine. An HA cluster consists of exactly two encryption engines. See "Creating high availability (HA) clusters" on page 510. For more information, refer to the following topics: "Failback option" on page 512 "Invoking failback" on page 512 Link Keys tab Connections between a switch and an NetApp LKM key vault require a shared link key. Link keys are used only with LKM key vaults. They are used to protect data encryption keys in transit to and from the key vault. There is a separate link key for each key vault for each switch. The link keys are configured for a switch but are stored in the encryption engines, and all the encryption engines in a group share the same link keys.
