Open Source Summit North America 2017

Did you recently replace your Hard Disk by a Solid-State Drive in your servers? Are you satisfied with the speed? What if I told you that it could go even faster? This talk will look at NVM Express, an interface specification for accessing SSDs over modern buses via PCI Express (instead of the old SATA) that enables the system to capitalize on the low latency and high level of internal parallelism that SSDs have. Helen will explain the technical details around the NVMe specification, its main concepts and the mechanisms that allow it to achieve a high level of parallelism in storage devices. She will also discuss the latest performance improvements to the NVMe protocol, particularly in virtualized environments, and where its support stands within the Linux Kernel.
