Library options
Redundant power supply
The MSL4048, MSL8048, and MSL8096 tape libraries have a redundant power supply option.
The redundant power supply allows the library to continue operating when one power supply fails.
With the redundant power supply system, the library can monitor the status of each power supply
and power supply fan. The redundant power supply can be installed without powering off the
library.
For instructions on installing the redundant power supply, see “Installing a redundant power
supply” (page 205).
HP StoreEver 1/8 G2 & MSL Encryption Kit
The encryption kit provides secure generation and storage of encryption keys. The encryption kit
may be used with any HP StoreEver 1/8 G2 Tape Autoloader or the MSL2024, MSL4048,
MSL8048 and MSL8096 Tape Libraries with at least one LTO-4 or later generation tape drive.
The encryption kit cannot be used with the MSL6000.
The encryption kit includes two USB key server tokens. One key server token is available for use
as backup for the other.
To use the encryption kit, a key server token is inserted in the USB port on the back of the library,
and encryption is enabled and configured from the RMI.
The encryption kit supports your manual security policies and procedures by providing secure
storage for encryption keys. Access to the key server tokens and their backup files is protected with
user-specified passwords. You will need to create processes to protect the tokens and secure the
passwords.
IMPORTANT: When encryption is enabled with the encryption kit, the library will not use encryption
keys from other sources, such as a key management system or application software. Disable
encryption in applications writing to the library when encryption is enabled with the Encryption
Kit. Applications that attempt to control encryption while encryption is enabled with the encryption
kit will not be able to do so, which can cause backups or other write operations to fail.
HP MSL Library Extender
The library extender combines two libraries to create a single extended library. Before installing
the extender, the libraries must be installed in the rack rails supplied with the libraries in adjacent
rack locations, one library above the other. See the example shown in Figure 1 (page 12).
