FIGURE 274
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
For more information, refer to the following topics:
"Failback option"
"Invoking failback"

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.
