Data cartridge capacity scaling
Capacity scaling enables faster random access to data.
The SET CAPACITY SCSI command enables a customer to capacity scale a data cartridge to enable faster random access. As an example, a customer can capacity scale a
data cartridge to 20% of its normal length that improves the average access time by almost a factor of 5. However, it also reduces the native capacity of the tape to 1.2 TB.
Encryption
The LTO tape drive supports host Application Managed Encryption (AME), with T10 encryption methods.
Data encryption is supported by LTO Ultrium 4 and later data cartridges only.
The encryption-enabled drive contains the necessary hardware and firmware to encrypt and decrypt host tape application data. Encryption policy and encryption keys are
provided by the host application. A drive digital certificate is installed at manufacturing time. Each drive receives a unique serial number and certificate. The T10
Application can validate each drive instance by checking the drive's digital certificate.
For details, see the IBM® Tape Device Drivers Encryption Support documentation, and the IBM LTO Ultrium Tape Drive SCSI Reference documentation.
