Hi:  We are running a 3090-400J with Ramac1 1.5GBCache 3494
     ATLw/(4)3590s via ATM.  We are flat out at 20 to 25 GB/day with ADSM
     and sharing the tape drives with DFSMS.  Of course the MF is doing
     many other things.

     Our early experience with an AIX ADSM server SSA DASD 3494 ATL
     (2)3590s via ATM is good.  It zips through 20 GB.  We rarely need the
     second drive while the MVS server could always use three.  The tape
     read/write speeds seem to make a big difference.  Also, this machine
     is almost 100% ADSM.

     We'll upgrade the MF to CMOS in Aug and high speed ESCON and are
     hopeful the faster channels will make the match more equal.

We are currently running the ADSM server on a IBM 9672-R25 under OS/390.
Our disk storage pools are on Ramac Raid-5 drives and our tapes are 3490E
housed in a ATL.  All TCP/IP traffic is being routed through a OSA 16/4
connection.  We are backing up Unix and NT applications.

I've been told that if you are backing up more than 100 gb of data in a 24
hour period then you should not run the ADSM server on a mainframe, but on a
Unix platform.  I would like to hear your (ADSM development, support, and
users) opinions/suggestions.

Best reguards.
