Multipathed PCI-e Storage - Keith Busch, Intel

Sign up or log in to save this to your schedule and see who's attending!

NVM-Express is a standard for PCI-e attached storage, and is fast becoming mainstream with many products available from various vendors today. The next generation of products under development brings new sets of enterprise features that require some enhancements to the software to fully take advantage of its capabilities, one of which is multipathing.

Multipathing PCI-e storage can have interesting applications, especially with larger NUMA configurations. While Linux has much of the components in place already, there are some kernel and driver enhancements required to make Linux readily work with such an NVMe device. This presentation will cover these proposed enhancements from nvme driver, block-multiqueue, and device-mapper's dm-mpath, as well as some user-space tips to get the most out of your h/w, and hopefully get some feedback discussion on the proposals.
