Chapter 3 Description
Tape Drives
Scalar i2000 User’s Guide 95
The control module and expansion modules have upper and lower drive
clusters. Each library must have at least one tape drive. Each drive cluster
can house up to six tape drives for a total of 12 drives. Additional drives
can be added to all expansion modules in the configuration. This enables
you to have a total of 96 drives.
Drives must be installed in bottom-to-top order in the control module
before any are added to the first expansion module. There are two six-
drive clusters in each of the first four modules.
Figure 17 on page 92 shows the locations of drives in the control module.
For details about the use of drives and cartridges, see Mixed Media
Support and Rules on page 97.
Fibre Channel LTO-1, LTO-2, LTO-3, LTO-4, DLT-S4, and SDLT-600
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 and SDLT drives follows.
Although the physical library can contain more
than one media domain or drive domain, you
cannot have a mix of domain types within a
partition (for example, LTO and DLT).
A single partition can have a mixture of drive
types and interface types within the same domain
(for example, LTO-1 and LTO-2 with SCSI or
Fibre Channel interfaces).
Quantum does not support mixing IBM LTO-3
and HP LTO-3 drives within a library.
When you add drives, you lose storage slots.
The term drive cluster defines a grouping of up to
six tape drives below or above the middle X-axis
rail.
