Thank you all for all the information.  We're not ready to start doing the 
in-depth research etc. so don't think I'm ignoring you if I don't respond 
immediately.  I'm buried in a different project now and once that is done I'll 
start researching this and will be reaching out for more information.

Subject: [EXTERNAL] Re: VTS question

Virtual tapes for mainframe:
IBM
Visara
Dell DLm 2500, 8500 (the largest IBM competitor) Interkom (AFAIK Luminex) 
Luminex MVT
Model9
ATSM zAppliance
Optica z/VT
Fujitsu Eternus
Hitachi (no details available)
Universal Software VTA (AFAIK ESCON only) Secure agent SDS CA VTape

Support for external tape library:
Fujitsu
Secureagent
Visara
IBM

Notes:
IBM VTS also support (much) smaller tape library with cheaper LTO drives. AFAIK 
it is TS4300.
TS4500 is scalable starting from single cabinet footprint.
IBM also support cloud storage (external or internal).
NO MORE REAL TAPES. The last tape connected to mainframe without "VTS 
appliance" was TS1140. Oracle/Sun/StorageTek went out of business. No plans to 
connect LTO drives.


HTH


BTW: I would like to know more about real tape attachment on the backend
- any input from vendors would be appreciated.
