VSE has VTAPE now.
CA has CDTAPE that works with z/VM now.
" Copyright Computer Associates International, Inc. 2003
CDTAPE simulates the CMS TAPE and VMFPLC2 commands allowing you to
run various software installation procedures like AIM or CIS using
tape image files instead of real tape volumes. Tape image files can
reside in CMS or on your TCP/IP connected workstation. You indicate
which location CDTAPE is to use by means of the CDTAPE START command."
I would think that IBM could to it right now too.

VTAPE is a Virtual Software Systems, Inc. (VSSI) commercial product and
already runs on VM. It wouldn't help in this case, because all VTAPE
does is redirect TAPE I/O to a local file, you'd still have to take that
really big file and FTP it. Now if VTAPE could redirect TAPE I/O to a
remote location "somehow" (i.e. open a TCPIP socket pointed to a Linux
server running a little VTAPE client to accept the data and write it to
a file) THAT would be sweet (and I'd bet you there is a market for such
a product.... Hint hint). :)

We could BEG IBM to add native VTAPE to z/VM .. even 'lowly VSE'
supports VTAPEs.

Hi Aria,
It's weird, sometimes it takes as little as 15 minutes to DDR2CMS a
3390-3 spindle, but most times it takes 45-50 minutes. But "all
spindles are not created equal", so you might have one that has very
little actual data on it (even if it is fully allocated for minidisks,
those minidisks might be substantially empty), and one that is full to
the gills. Likewise, some data compacts better than others (for example
one spindle contains a bunch of 'zip' files sent to us by PC users,
those files are already well compressed and further compaction isn't
likely).
Again, if I can't (quickly) find a means to read the disk and write to a
TCPIP stream directly (with a collector on the remote end, of course),
I'll probably replace DDR2CMS with PIPEDDR to create the intermediate
files before transmitting them.

I wish!!! I am on a 2066-0B1 with ESCON channels also. The DASD is an
EMC 8430 with lots of cache however.
