Tape is a very mature technology. I expect that more vendors will provide an object layer to tape, allowing tape to become a standardized data tier. Software-defined storage (SDS) is paving the way for this.
Back in December 2007, when the concept of object-based storage was first defined by IDC, tape was actually mentioned as a potential media tier.
It has certainly taken longer than many have thought, but by 2015, I believe that SDS solutions will be able to manage, provision and control on-premises disk and cloud-based capacity, along with LTO/LTFS tape. Improved algorithms will be able to better understand the patterns of access to data, allowing tape to once again become the preferred low-cost, capacity tier.
