The following components are required to use encryption:
v
Encryption-enabled tape drive
v
Keystore
v
Key manager
Prerequisites for using encryption
Certain hardware and software prerequisites must be met before using encryption
with the TS4500 tape library.
With the TS4500 tape library, encryption is managed at the logical library level. All
encryption-enabled drives that are assigned to a logical library use the same
method of encryption.
The rules for setting up encryption differ based on whether the library is installed
with 3592 or LTO tape drives, and whether you use Library-Managed Encryption
(LME) or Application-Managed Encryption (AME).
If the library contains 3592 tape drives, the following prerequisites apply:
v
IBM Security Key Lifecycle Manager (SKLM), formerly the Tivoli Key Lifecycle
Manager, must be attached to the TS4500 and configured for LME .
v
Tape drives must be enabled for encryption from the Logical Libraries page of
the TS4500 management GUI.
If the library contains LTO tape drives, the following prerequisites apply:
v
Tape drives must be enabled for encryption from the Logical Libraries page of
the TS4500 management GUI.
v
Feature code 1604, Transparent LTO Encryption, is required for LTO tape drives
if using LME.
v
SKLM is required as the key manager when using LME with LTO.
Using LTO tape drive media
The section introduces information about using LTO tape drive media.
The TS4500 tape library automates the storage and movement of IBM LTO tape
cartridges.
Overview of LTO tape drive media
Within the TS4500 tape library and subject to certain restrictions, the supported
LTO tape drives use the following cartridge types.
v
12 TB LTO 8 Data Cartridge (LTO 8 cartridge)
v
12 TB LTO 8 WORM Data Cartridge (LTO 8 cartridge)
v
9 TB LTO M8 Data Cartridge (LTO M8 cartridge)
v
6 TB LTO 7 Data Cartridge (LTO 7 cartridge)
v
6 TB LTO 7 WORM Data Cartridge (LTO 7 cartridge)
v
2.5 TB LTO 6 Data Cartridge (LTO 6 cartridge)
v
2.5 TB LTO 6 WORM Data Cartridge (LTO 6 cartridge)
v
1.5 TB LTO 5 Data Cartridge (LTO 5 cartridge)
v
1.5 TB LTO 5 WORM Data Cartridge (LTO 5 cartridge)
v
800 GB LTO 4 Data Cartridge (LTO 4 cartridge)
