Linux is usually the first target for vendors with the most cutting edge types of storage and file system technologies. The community was the first to bring parallel NFS into production quality and has been at the bleeding edge of dealing with very high speed, low latency storage devices like PCI-e SSDs. This talk gives an overview of two new technologies at the opposite ends of the speed and capacity spectrum: DRAM class persistent memory and very dense "shingled" drives. The talk gives an overview of what the technologies are, what the ongoing work is in upstream and some of the choices we have in supporting these new devices. Finally, the talk will give an overview of how these new technologies are likely to be deployed both in traditional, enterprise servers and in the hardware that underpins modern cloud systems.
