The NVSRAM file in this directory is for the DS4300 storage subsystem 
configurations with either the DS4300 storage subsystem by itself or the 
DS4300 storage subsystem with Fibre Channel drive expansion enclosures 
(EXP700/EXP710) only attached. This is also the correct NVSRAM file to use 
for the DS4300 storage subsystems with the FC/SATA intermix premium feature 
enabled when the DS4300 storage subsystem controller firmware is of version 
06.12.xx.xx. The FC/SATA intermix premium feature enables the support of the 
EXP700/ EXP710 and the EXP100 drive expansion enclosures behind a DS4300 
storage subsystem. 


IMPORTANT:
The DS4000 storage subsystem controller firmware version 06.12.xx.xx supports 
the FC/SATA intermix premium feature via a premium feature key file instead 
of a NVSRAM file as with controller firmware version 06.10.xx.xx. A premium 
key file, instead of a NVSRAM file, is now required to enable the FC/SATA 
premium feature intermix in a DS4000 storage server. Please refer to the 
FC/SATA premium feature intermix activation card for instructions to generate 
the FC/SATA intermix premium feature key file. The CD-ROM that is shipped with 
the FC/SATA intermix entitlement kit also has the pdf version of the IBM 
TotalStorage DS4000 Fibre Channel and Serial ATA Intermix Premium Feature 
Installation Overview publication which provides useful information.



In addition, this is also not the correct NVSRAM file for the DS4300 storage 
subsystem configurations that have only (up to eight) EXP100 drive expansion 
enclosures attached. Please refer to the NVSRAM file named 
N1722F600R28enc2.dlp in the "For attachment of EXP100(SATA) enclosures only" 
directory in this CD, instead.


Please contact IBM support for more information, if required.
  
  
Note: The FC/SATA drive type intermixing behind a DS4000 storage subsystem 
requires the purchase of the FC/SATA intermix premium feature entitlement. 
Please contact your IBM resellers or representatives for more information.
