DD6300 and DS60 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.
• For redundancy, the two connections from a system to a set of shelves must use ports on different SAS I/O modules.
• 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.
• ES30 SATA shelves must be on their own chain.
• If ES30 SAS shelves are on the same chain as a DS60, the maximum number of shelves on that chain is 5.
