Robotic Rail Assemblies
Figure 8
shows an example of the HandBot and rail assembly in the SL8500.
•
Each SL8500 has four separate robotic rail assemblies. These rail
assemblies provide both power and communication signals to its own
individual robotic system.
•
The robotic systems in the SL8500 are called HandBots. Each HandBot
can service up to 16 tape drives and all of the tape cartridges for that rail.
•
Spanning across the four rail assemblies are two elevators. These
elevators perform an internal pass-thru port operation that allows any tape
cartridge to have access to any tape drive in the SL8500 library and within
an SL8500 library complex.

To optimize system performance, the HandBots automatically implement the
Fast Load
capability. Once a HandBot successfully inserts a tape cartridge
into a drive, it is immediately available for the next request and does not wait
until the drive reports that the cartridge has been loaded. The SL8500 library
control electronics waits to return the response to the mount request until it
detects that the tape drive has successfully loaded the cartridge tape.
Currently, there are two HandBot configurations:
A HandBot assembly consists of:
