The DD9500 base (non-Extended Retention) and HA systems support six chains.
The following figures show cabling for base systems, HA systems, and systems with
the Extended Retention or DD Cloud Tier software option.
Note
The DD9500 system running DD OS 5.6 does not support any ES20 shelves.
Note
In DD OS 5.7 and later releases, ES20 shelves are supported on a DD9500 system only
during the period required for shelf migration of the data to another shelf.
Extra planning and reconfiguration may be required to add DS60 shelves to system
with ES20 shelves, ES30 SATA shelves, or a combination. ES20 shelves must be on
their own set. Minimize the ES20 set count by combining up to four ES20s per set.
