OCTOBER 2006 MAGNUM 1X7 LTO AUTOLOADER
121
PERFORMANCE SPECIFICATIONS
The autoloader’s power-on sequence time is approximately:
60 seconds when the autoloader contains seven cartridges with bar code
labels.
160 seconds when the autoloader contains seven cartridges without bar
code labels.
CARTRIDGE INVENTORY TIMES
An application can issue a command to the autoloader to check all cells for
cartridges and scan bar code labels. After checking the cells, the autoloader
updates its cartridge inventory.
The average cartridge inventory time for 7 cartridges is approximately:
35 seconds when the autoloader contains seven cartridges with bar code
labels.
130 seconds when the autoloader contains seven cartridges without bar
code labels.
Whenever a cartridge is inserted or removed through the cartridge access port,
the autoloader performs a cartridge inventory on the affected cell.
The average time for an individual cartridge cell inventory is:
5 seconds when the cartridge has a bar code label.
20 seconds when the cartridge does not have a bar code label.
MOVE COMPLETE TIME
Move complete time is the time it takes the autoloader to remove a cartridge
from the tape drive, return it to its cell, position a different cell in front of the
tape drive, and load the new cartridge into the tape drive.
Move complete time is measured from the time the autoloader receives the
move command to the time the autoloader returns status to the initiator
indicating that the move is complete. The average move complete time is
approximately 26 seconds.
RELIABILITY
The mean cycles between failures (MCBF) for the autoloader is 250,000 cycles.
This value does not include failures attributable to the tape drive or cartridges.
During one full cycle, the autoloader completes the following actions:
Picks a cartridge from the tape drive
Places the cartridge in its cell
Positions a different cell in front of the tape drive
Loads the new cartridge into the tape drive
