Not brand-new, but I've not seen it mentioned on here so far. Seagate Kinetic essentially enables HDDs to present themselves directly over Ethernet as Swift object storage:

If the CPUs on these drives have enough oomph for Swift, what about Ceph OSDs?
Add in some DHCP option based auto-configure mechanism and a small SLC SSD in each drive (like hybrid drives; Kinetic graphics hint at this already: http://www.seagate.com/www-content/ti-dm/_shared/images/figure-3-drive-application-management-storage-software-api-732x642.png) so we could also eliminate the storage server layer, get smaller failure domains, and solve the journalling problem - and ultimately reduce cost and complexity. Basically build a rack with hundreds of hot-plug Ethernet HDD ports...
Forgive me, I'm just thinking out-loud...
Kinetic is interesting, but I think it's going to find more uptake among big Open Compute users like Facebook than in general distributed storage systems. In particular, these drives don't appear to have the CPU power required to run OSDs, and their native interfaces don't have the strength to be useful underneath.
