It is what I understood from announcement, once tape drives will not connect
directly to z/OS channel but to VTS for destage.
VTS emulates 3490/3590 and can destage to any kind of tape, it is just a bunch
of bits to be recorded in tape.

Assunto: Re: RES: TS1140 tape transports
Does it mean one can replace his TS1140 drives with LTO?
I don't think so.
Correction: I don't think it is possible for z/OS or VTS clients. Note:
Windows/Unix host could use TS1140 natively.
