Bar Code Reader
The bar code reader is an integral part of the library Accessor. The bar code reader
reads each cartridge bar code label that identify the types of cartridge magazines and
tape drive installed in the library and 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 and Ultrium 4 Half-High Tape Drives support the Serial Attached SCSI
(SAS) interface. They both have one Mini-SAS (SFF-8088) connector, and can be
connected to a Mini-SAS (SFF-8088) or SAS (SFF-8470) at the host adapter end with
the appropriate cable.
A drive with a SAS (Serial Attached SCSI) interface can be linked directly to
controllers. SAS is a performance improvement over traditional SCSI because SAS
enables multiple devices (up to 128) of different sizes and types to be connected
simultaneously with thinner and longer cables; its full-duplex signal transmission
supports 3.0 Gb/s. In addition, the TS2900 Tape Autoloader can be hot-plugged. SAS
drives will auto-negotiate speed.
Encryption
The LTO Ultrium 4 Tape Drive supports host Application Managed Encryption
(AME), Library Managed Encryption (LME), and System Managed Encryption
(SME). Data encryption is supported by the LTO Ultrium 4 Tape Drive (3572-S4H)
only; the Ultrium 3 Tape Drive (3572-S3H) does not support encryption.
Note:
Application Managed Encryption (AME) does not require a key. Library
Managed Encryption (LME) and System Managed Encryption (SME) require 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.
The encryption-capable library firmware allows the user to select “None” or
“Application Managed Encryption” from the Web User Interface. If a valid
Transparent Encryption license key has been previously entered, “System Managed
Encryption” or “Library Managed Encryption” can also be selected. The factory
default is “None.”
Accessor locking screw The Accessor locking screw is used to lock the accessor in place during
transportation.
Important: Remove the Accessor locking screw before powering ON the
library.
Air vent These vents allow air to escape from the power supply and tape drive
sled.
