HP Enterprise Secure Key Manager Considerations for using an encryption key server, Licensing

KMIP-based key servers

The 1/8 G2 Tape Autoloader and the MSL2024, MSL4048, MSL6480, MSL8048, and MSL8096 Tape Libraries support integration with non-HP key servers through the KMIP protocol. This requires a KMIP Encryption license for the library. For configuration information, see “KMIP-based key server integration” (page 12).

Considerations for using an encryption key server

The libraries only support the configuration of one encryption key method at a time. For example, if the library is configured to obtain encryption keys from an encryption key server, it will not also be able to obtain encryption keys from the HP MSL Encryption Kit nor from a backup application.

Licensing

The KMIP and ESKM features require that the applicable license for the library be installed before the feature can be enabled and configured.
