Sachin, 
if you put the DS4700 behind a SAN Volume Controller you can use TSM for 
ACS (module for SAP) to 
perform all process steps necessary to generate a complete and consistent 
FlashCopy under control
of BR*Tools. TSM for ACS is built upon the CIM interface and an implicit 
background copy option which
the DS 4700 does not provide.
To use the DS4700 for FlashCopy natively you have to write your own 
scripts for all the necessary 
process steps according to the splitint interface (SAP BC-BRS). Backup is 
initiated from an auxiliary 
server using BRBackup which will first determine all files to be backed up 
and then request a copy via
the splitint interface. Splitint finishes when the files are mounted on 
the auxiliary server, and BRBackup 
then calls TSM for ERP via the backint interface to copy the backed up 
files to TSM. 
As mentioned in an earlier reply, no SAP software needs to be installed on 
the auxiliary server. 
Executables are accessed through NFS mounts as described in this Redbook:
