For full details on the requirements for intermixing FAStT EXP500 and DS4000
EXP700 storage expansion enclosures, refer to the IBM TotalStorage DS4000
EXP700 and EXP710 Storage Expansion Enclosures Installation, User's, and
Maintenance Guide. You can also refer to the IBM TotalStorage DS4000 Hard Drive
and Storage Expansion Enclosure Installation and Migration Guide.
Intermixing DS4000 EXP710s and DS4000 EXP700s: You can intermix DS4000
EXP710s and DS4000 EXP700s in the same drive loop with a DS4500 Storage
Server, but all DS4000 EXP710s must be grouped together.
Attention:
intermixing DS4000 EXP710s and EXP700s is version 9326. Verify that the ESM
firmware for all DS4000 EXP700s is at version 9326 or higher before intermixing
DS4000 EXP700s with EXP710s.
In order to attach DS4000 EXP710 storage expansion enclosures to a DS4500
Storage Server, the DS4500 Storage Server controller firmware must be at version
06.xx.xx.xx or higher.
A fully configured DS4500 Storage Server supports a maximum of 16 IBM DS4000
EXP700 or EXP710 storage expansion enclosures (8 storage expansion enclosures
per drive-loop pair), or 224 drives, using dual pairs of redundant drive loops.

The requirements for intermixing DS4000 EXP710s and EXP700s state that all
DS4000 EXP710s in a redundant drive loop must be grouped together. IBM
does not support intermixed drive loop configurations in which all DS4000
EXP710s are not grouped together.
