Normally I don't like to just plug something new. However, I am willing to make an exception for something new and different. I want to do a brief foray into the world of mainframe attach virtual tape.
We danced around this a little while back when I talked about open systems virtual tape and the market share of the respective players. Specifically, about how technology and market share in open systems virtual tape, and technology and market share in mainframe attach virtual tape are two totally different things, and it is misleading at best to say that one has any genuine relevance to the other.
In that post, I don't think I made any bones about the fact that EMC is not a market leader in the mainframe virtual tape space. I think we are honest enough to admit that the two market leaders (in terms of share and units shipped) are Sun and IBM. However, we have recently introduced a new mainframe virtual tape offering--the Disk Library for Mainframe, or DLM--and it is pretty different than anything else out there.
The big difference? There is no tape.
