Performance specifications
Capacity
The autoloader can accommodate as many as eight LTO tape cartridges. The
storage capacity of the autoloader depends on the type of cartridge and the type
of data being stored.
Tape drive performance
When installed in the autoloader, the tape drive performs within its
specifications. A minimum of an Ultra2 LVD-capable controller that can transfer
data at least 80 MB/second is required. For more information about tape drive
performance specifications, see “Specifications” on page 51.
Autoloader self-test times
Each time the autoloader is turned on, it performs a power-on self-test (POST).
POST includes a self-test of the control electronics, initialization of the
mechanical components, and a cartridge inventory. The POST time is measured
from the time the autoloader is turned on until the autoloader indicates Ready
status. The maximum time required for POST is 65 seconds.
The autoloader also performs a self-test when you select
Library Test from the
Operator’s Panel or in response to a SEND DIAGNOSTICS SCSI command. The
maximum time required for this self-test is nine seconds.
If the cartridges are correctly installed, the autoloader is ready for operation
after performing either a POST or a self-test. If the autoloader encounters a
problem during a POST or the self-test, it reports an error on the LCD.
Initial element status time
When an initiator sends an INITIALIZE ELEMENT STATUS (IES) command, the
autoloader checks each cartridge slot for the presence of a cartridge. The
autoloader requires 21 seconds to perform an IES command.
