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. :/ Speaker: Heonyoung Yeom 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 Ceph.
