Tape Drives
1
M-Series tape libraries are equipped with SCSI tape drives. One SCSI bus
is provided for the library robotics and for each SCSI tape drive installed.
These SCSI buses are SCSI-2 fast/wide (8/16 bit), Ultra SCSI, Ultra 2
SCSI, Ultra 3 SCSI, or Ultra 160 SCSI, depending on the drives installed.
LVD SCSI configurations have a maximum allowable bus length of 12
meters. To determine the cable length of the bus, measure the lengths of
the SCSI cables connecting each device to that bus and add those lengths
together. To that total length, add 12.25 inches (31.10 cm) for the internal
SCSI cable length of each SCSI tape drive.
Library Scalability
1
The ATL M1500 and ATL M2500 library modules can be used as stand-
alone libraries, or can be combined with other ATL M1500 and
ATL M2500 library modules and a StackLink mechanism in a standard
19-inch rack to form a larger library system (called a multiple library
stack). The multiple library stack appears as a single large capacity library
to the host.
The StackLink mechanism connects the library modules in the multiple
library stack and transports cartridges from module to module. Each tape
drive has access to all the tape cartridges in the stack.
Once the StackLink mechanism is installed in the rack, you can add
library modules simply by sliding them into place and making the
necessary electrical connections.
lists the capacities of all the sizes of multiple library stack you can
create using ATL M1500 library modules.
lists the capacities of all
the sizes of multiple library stack you can create using ATL M2500 library
modules. You can obtain different capacities by combining ATL M1500
and ATL M2500 library modules in a multiple library stack.
