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.

Hello list,

We currently have a very small TS7760 grid, one frame at our primary site 
replicating to a secondary frame at out alternate site.  The alternate site is 
a TS7760T with an old single frame TS3584 with 5 3592-E08 drives hanging off 
the back of it.  We just found out the 3584 is out of support and the 7760s are 
falling off the end of the year.  We're looking at what our options are.  
Obviously the easiest choice for the 7760 replacements are 7770s.  I know there 
are a couple competitors out there, EMC/Dell and maybe Luminex are options for 
the VTS.  Any others?

More interesting to me right now is a replacement for the 3584.  I know IBM has a TS4500 
library but that seems like overkill for a site our size.   Is there a "baby 
brother" to the 4500 or some other tape back end we could use?  I'm obviously 
looking in the wrong place because I'm not seeing anything talking about hanging tape off 
the back end of the TS7770T.
