There are advantage and disadvantage in both LTO and 3590's.  We are sticking 
with 3590's.

        Read ALL the fine print on LTO drives & associated media !
        They are a far cry from 3590's !
                check the life expectancy in mounts, full reel reads/writes, 
etc...

        I think it is more of a question when a VTS replacement would become
        available and 3590 is significantly slower than other technologies.  
There
        is still development going on for the 3494 library itself.  There will 
be a
        replacement 3590 drive soon.  It is not clear if that drive will be in 
the
        3494 library or in a LTO type library.  My guess is both, but I have not
        seen a product direction, so anything is possible.

        At this point, I would review my data requirements, install new 
capacity in
        LTO for open systems if it is more cost effective, and seek an answer 
from
        IBM.

        Does anybody have an idea what is reasonable to expect for the lifespan 
of a
        3494 library?

        My manager wants to know when we should budget for a new one. But I've 
never
        heard of anybody replacing a 3494 because of age - just upgrading to new
        drives!
