Hi ,
Question is what do you want to use it for . As an OSD it wont cut it.
Maybe as an iscsi target and YMMV

- Ceph had to be compiled and deployed.

James Hughes talked about these at MSST last year, and some of his colleagues demonstrated the hardware: <http://storageconference.us/2014/Presentations/Hughes.pdf>
For tinkering purposes there is java based simulator: <https://developers.seagate.com/display/KV/Kinetic+Open+Storage+Documentation+Wiki>
The drives do use a key/value interface.
