The NVSRAM in this folder is for the DS4300 dual-controller storage subsystem 
configurations with either the DS4300 storage subsystem by itself or the 
DS4300 storage subsystem with Fibre Channel drive expansion enclosures only 
attached (i.e. EXP700, EXP710 or EXP810 (with only Fibre Channel Enhance-Disk 
Drive Modules (E-DDMs) installed).) This is also the correct NVSRAM file for 
the DS4300 storage subsystems with the FC/SATA intermix premium feature, 
which will enable the intermix support of the EXP700/EXP710 or the 
EXP710/EXP810 (with either FC or SATA drives installed in the EXP810) and the 
EXP100 drive expansion enclosures behind a DS4300 storage subsystem. 

This is  not the correct NVSRAM file for the DS4300 storage subsystem 
configurations that have only (up to eight) EXP100 drive expansion enclosures 
attached or up to seven EXP810 drive expansion enclosures with ONLY SATA E-
DDMs installed attached. Please refer to the NVSRAM file in the 
For_attachment_of_SATA_enclosures_only directory for the correct 
NVSRAM file.


IMPORTANT:
The DS4000 storage subsystem controller firmware version 06.23.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.


Please contact IBM reseller or representatives 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.
