Library Scalability (Stacked Configurations)
The Scalar 50 library modules can be used as stand-alone libraries, or
combined with other Scalar 50 library modules in a standard 19-inch rack
to form a larger library system (called a multiple library stack). The
multiple library or stacked configuration appears as a single large
capacity library (or multiple libraries if partitioned) to the host (see
).
Multiple Library Stack
Requirements
1
To ensure the proper operation of your multiple library stack, review the
following list of multiple library stack requirements:
• Multiple library stacks that contain a Scalar 50 can NOT exceed two
library cabinets.
• The Scalar 50 must be the Master library in a multiple library stack
containing PX502 libraries.
• The Master library must always be in the bottom most position in the
library stack.
• If a Scalar 50 is stacked with PX502 libraries, the PX502 can NOT
contain an HP LTO-2 tape drive or a FC1202 Fibre Channel bridge.
These devices are not supported by Scalar 50.
• All Scalar 50 libraries must have full capacity enabled.
• A library that contains SAS drives cannot be shared with SCSI or
Fibre Channel libraries.
• If your Scalar 50 is not already enabled with full slot capacity, you
must initially configure the Scalar 50 libraries and enable
Full
capacity with a
Capacity Key
before configuring the cabinets as
Master and Slave libraries (see
on page 125 for more
Capacity
Key
information).
