From
Hemant,
are you using FC or SATA drives on the 6140 S-vols? Also assuming this is
virtualized behind the 9990V in order to use ShadowImage. I'd probably
recommend some testing independent of NetBackup to see how fast you can
pull data off these volumes. Such as use something like ufsdump, tar

Have you asked your storage admin to check what your storage array
