be attached behind a

six, resulting in the
maximum number of
drives being less than

Note: The maximum number of supported drives varies depending on the number of EXPs
with 16 drives in the configuration versus the number of EXPs with 14 drives in the
configuration.
To attach DS4000 EXP drive expansion enclosures to a DS4300, refer to the IBM
System Storage DS4000 Hard Drive and Storage Expansion Enclosure Installation
and Migration Guide for the latest information on the required version of the
DS4300 controller firmware and the supported combination of enclosure types
intermix behind a DS4300 subsystem. In addition, you must purchase the FC/SATA
Enclosure Intermix premium option to combine SATA disk drives with fibre channel
drives in the same DS4300 Storage Subsystem configuration.
Table 4 on page 8 summarizes the features of the storage subsystem. For a list of
the operating specifications, such as weight, height, and heat output, see Table 7 on
