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 and later Half Height Tape Drives support the Serial Attached SCSI (SAS) interface. 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 6.0
Gb/s (S4H and later). In addition, the TL1000 Tape Autoloader is hot-plugged, if necessary. SAS drives
can auto-negotiate speed.
Encryption
The LTO Ultrium 4 and later Tape Drives support host Application Managed Encryption (AME) with T10
encryption methods, for SAS drives. Data encryption is only supported by LTO Ultrium 4 Data
Cartridges and later.
Important: Contact your Dell technical sales representative about the availability of Library Managed
Encryption (LME).
Note: Application Managed Encryption (AME) does not require a key. Library Managed Encryption
(LME) is available only by purchasing a library with the Library Managed Encryption enabled at point of
sale.
Note: When available, library-managed encryption is only offered for purchase at point of sale on LTO-8,
LTO-6, and LTO-7 TL1000 tape libraries. Library Managed Encryption is not offered as an upgrade on
existing TL1000 tape libraries.
The library is powered ON when the power supply switch on the
rear panel is ON (|). The library has no independent power switch
on the front panel.
Serial-attached SCSI host interface cable connection. The Ultrium 4,
5, 6, and 7 SAS drives use the SFF-8088 connection at the drive end
and SFF-8088 or SFF-8470 at the host adapter end.
This port is used to connect the library to a network.
The accessor locking screw is used to lock the accessor in place
during transportation.
Important: Remove the accessor locking screw before the library is
powered ON.
Air vent
These vents allow air to escape from the power supply and tape
drive sled.
