The DS5020 does
not have the
necessary feature
options to support
the storage
expansion
enclosures.
The base DS5020 storage
subsystem supports up to 32
drives, which includes 16 drives
in the DS5020 chassis and the
16 more drives if an EXP520
storage expansion enclosure is
attached. Toattach more than 32
drives, you much purchase the
applicable feature option. For
example, to attach one or more
EXP810 storage expansion
enclosures to the EXP520
storage subsystem, you must
have the feature option for the
EXP810. Contact your IBM
marketing representative for more
information about purchasing
feature options.
