DD9300 and ES30 shelf guidelines

The system rediscovers newly configured shelves after it restarts. You can power off the system and recable shelves to any other position in a set, or to another set. To take advantage of this flexibility, you need to follow these rules before making any cabling changes:

Do not exceed the maximum shelf configuration values for your system as listed in the following table below.
Use the Installation and Setup Guide for your system to minimize the chance of a cabling mistake.
A system cannot exceed its maximum raw external shelf capacity, regardless of added shelf capacity.
DD6800 systems support ES30 SATA shelves after controller upgrades from older models.
ES30 SATA shelves must be on their own chain.
