  disable the cache.  The result was severe performance degradation. 
  For DS4400 and DS4500, the controller firmware version was 
  05.40.11.03. 
  For the DS4300 Turbo, the new controller firmware version was 
  05.40.11.04.

Maintenance Release

Version 05.40.03.05, 9/21/2004 for the DS4300 Turbo, DS4400, and DS4500. 
 This is the initial release of the DS4000 storage subsystem controller 
 firmware for the 05.40.xx.xx code thread. A list of new features are as 
 follows:
 
 - Support for IBM TotalStorage DS4300 Turbo
 - Support for VolumeCopy copy service premium feature
 - 256 logical drives per storage mapping partition
 - Persistent reservations
 - User control of network parameters. The user can now change the 
   controller IP addresses via the Subsystem Management window interface.
 - Support for larger than 2TB arrays. The maximum logical drive size is 
   still 2 Tera bytes. 
 - Support for the creation of logical drives with a segment size of 512K
   using the script engines or SMcli
