Figure 1: Storage slot and mailslot numbering
The robot cannot access the lowest row of storage slots in the library. If the library only has a base
module, the library will have 32 storage slots. Each expansion module adds 40 storage slots.
Figure 2: The lowest row of storage slots in the library are inaccessible to the robot.
If an expansion module is installed below the base module, the inaccessible storage slots will be in the
lowest expansion module and all of the storage slots in the base module will be accessible.
The numbers associated with the inaccessible storage slots are not used. For example, storage slots 1
and 6, and mailslot MS1 are not visible in the RMI.
IMPORTANT:
Do not install cartridges in any of the eight lowest storage slots in the library. If the library detects
cartridges in the eight lowest slots, it will mark them as inaccessible and will not use them for
backup operations.
Encryption
Encryption protects data from unauthorized access and use. The data is changed into a form that can
only be read with the key used to encrypt the data.
The LTO-4 and later generation tape drives can encrypt data while writing, and decrypt data when
reading. Hardware-based data encryption can be used with or without compression while maintaining the
full speed and capacity of the tape drive and media. LTO tape drives use the 256-bit version of the
industry-standard AES encrypting algorithm to protect your data.
To use the tape drive hardware-based encryption feature, you need all the following:
•
The "HPE 1/8 G2 Tape Autoloader and MSL Tape Libraries Encryption Kit" or a supported key server
or a backup application that supports hardware-based data encryption.
•
The KMIP feature license when using a KMIP key manager.
•
LTO-4 or later generation media. The tape drive will not encrypt data when writing to LTO-3 or earlier
generation media.
