Hi Jennifer,

Can you update sched with the following invite keynote for Thursday
morning?  I think a 20m slot?

BTW I think we're going to need to get creative to fit in all of the
keynote slots (sponsored and otherwise)... maybe reduce the time intervals
later in the day or something.  :/

Title: The impact of fast storage on the distributed file system

With the introduction of the SSD and its wide spread use these days, the
world of storage is changing with far reaching effect on operating
systems, computer architecture and distributed file system. While confined
within the SATA interface, the effect was minimal. However, the NVMe
interface has changed everything upside down.

Traditionally, the storage device has been a black box. The interface
cleanly separated the applications and operating systems from the inner
workings of the storage device, making everything simple and clear.
However, the sudden increase in speed and parallelism as well as the
unique physical characteristics of the storage devices make it necessary
to somehow coordinate the actions between the storage device and the
system software.

In this talk, I will look at the actual changes of the storage device
itself and its impact on the storage stack of the operating systems and
how this change would affect the distributed files systems, especially
