        Subject:        Expanding our system


            We currently have a 3494 library with two 3490E1A drives
attached to a WinNT4 box running quad Xeon 550's and a gig of RAM. TSM is
version 4.2. We have about 30-40gig of data coming in over about an eight
hour time window each evening and night. Things are fine for now. We are
looking to do some improvements in the next several months.

The 3494 can be upgraded to 3590E1A using direct Fibre Channel attach.  I
do not know if the 3490's can coexist with the Fibre Channel 3590's, but I
do have customers that have 3494's with both SCSI 3490's and SCSI 3590's
in the same library.  They can not be in the same frame, but if they are
in separate frames it works well.

            First thing we would like to do is to reload the server with
Win
2000 and TSM version 5.xx. In our shop, we can only speak MS. Other OS's
aren't an option. This we would like to do in 3-4 months. I think we can
handle this ourselves.

            Next on the agenda, we are working towards getting some kind
of
a SAN in the budget for the first of the year. I don't know all of the
details at the moment but they are talking about 3-4 terabyte capacity.
Don't know how this will impact on new data coming into TSM. But the boss
man wants to see about adding another complete library with two more tape
drives.

For 3-4 Terabytes in 8 hours you would need 10 SCSI attached 3590E1A's.
For fibre channel you might be able to use less, but realistically you are
probably running what 20 - 30 Windows servers.  You will 10 drives just to
be able to do the tape copy pools and DRM management

            The people we that installed our original system are gone so
we
can't go back to them for more hardware. Any suggestions on someone to do
this for us?
