Note: The term drive cluster defines a grouping of up to six tape
drives below or above the middle X-axis rail.
Figure 18 on page 30 shows the locations of drives in the control
module. For details about the use of drives and cartridges, see

Fibre Channel LTO-1, LTO-2, LTO-3, LTO-4, LTO-5, LTO-6 and LTO-7 drives
can be connected to drive-aggregating Fibre Channel I/O blades or
directly attached to a host, so these drives do not require an external
SNC. More detailed information about LTO drives follows.
Six generations of LTO drives are supported, but they are not fully
compatible as shown in
