Dell PowerVault TL1000 - Manual (Page 24)

Bar code reader
The bar code reader is a part of the library accessor. The bar code reader reads
each cartridge bar code label that identifies the types of cartridge magazines and
tape drive that is installed in the library. It also provides inventory feedback to the
host application, Operator Panel, and Web User Interface. The library stores the
customized inventory data in memory. Library firmware supports a 6 or
8-character volume serial number (VOLSER) on the bar code label on the tape
cartridge.
SAS host interface
The Ultrium 4, Ultrium 5, and Ultrium 6 Half-High Tape Drives support the Serial
Attached SCSI (SAS) interface. The SFF-8088 SAS connector on the Ultrium 4,
Ultrium 5, and Ultrium 6 is compatible with SAS-1 or SAS-2 cables.
A drive with a SAS (Serial Attached SCSI) interface is linked directly to controllers.
SAS is a performance improvement over traditional SCSI. SAS enables multiple
devices (up to 128) of different sizes and types to connect simultaneously with
thinner and longer cables. Its full-duplex signal transmission supports 6.0 Gb/s
(S4H, S5H, and S6H). In addition, the TL1000 Tape Autoloader is hot-plugged, if
necessary. SAS drives can auto-negotiate speed.
Encryption
The LTO Ultrium 6, Ultrium 5, and Ultrium 4 Tape Drives support host
Application Managed Encryption (AME) with T10 encryption methods, for SAS
drives. Data encryption is supported by LTO Ultrium 6, Ultrium 5, and Ultrium 4
Data Cartridges only.
Note: Application Managed Encryption (AME) does not require a key.
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 or host server. A drive digital certificate
is installed at manufacturing time. Each drive receives a unique serial number and
certificate. The T10 application validates each drive instance by checking the
drive’s digital certificate.
The LTO Ultrium encryption environment is complex and requires knowledge
beyond that of product trained Service Support Representatives (SSRs). The
Encryption function on tape drives (desktop, stand-alone, and within libraries) is
configured and managed by the customer. In some instances, SSRs are required to
enable encryption at a hardware level when service access or service password
controlled access is required. Customer setup support is by Field Technical Sales
Support (FTSS), customer documentation, and software support for encryption
software problems. Customer 'how to' support is also provided by way of support
line contract.
The encryption-capable library firmware allows the user to select None or
Application Managed
encryption from the Web User Interface. The factory default
is None.
