Bar Code Reader; Sas Host Interface; Encryption; Leader Pin - IBM TS2900 Setup, Operator, And Service Manual

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 3 Half Height Tape Drives and later, support the Serial Attached SCSI (SAS) interface. They
have one Mini-SAS (SFF-8088) connector, and are connected to a Mini-SAS (SFF-8088) or SAS (SFF-8470)
at the host adapter end with the appropriate cable. The SFF-8088 SAS connectors on the Ultrium 3 and
Ultrium 4 are compatible with SAS-1 cables. The SFF-8088 SAS connector on the Ultrium 5 tape drives
and later, are 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 3.0
Gb/s (S3H and S4H) or 6.0 Gb/s for S4H and later. In addition, the TS2900 Tape Autoloader is
hot-plugged, if necessary. SAS drives can auto-negotiate speed.
Note: The Ultrium 4 Half Height tape drive in S4H libraries that are manufactured after March 2011
support 6.0 Gb/s.

Encryption

The LTO Ultrium 4 and later Tape Drives support host Application Managed Encryption (AME) and
Library Managed Encryption (LME) with T10 encryption methods, for SAS and Fibre Channel drives.
Data encryption is only supported by LTO Ultrium 4 Data Cartridges and later. Encryption is also
supported by library firmware version 4.0 or later.
Note: Application Managed Encryption (AME) does not require a key. Library Managed Encryption
(LME) requires a license key, which is available by purchasing Feature Code 5901.
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, whether it's a
desktop, a stand-alone drive, or 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.
Use the encryption-capable library firmware to select None or Application Managed encryption from the
Web User Interface. If you did not previously enter a valid Transparent Encryption license key, you can
also select Library Managed Encryption. The factory default is None.
