NVM Express has brought PCIe attached storage to the mainstream, and we're seeing this fast interface replacing solid state storage on slower, albeit more mature, buses. There is a strong user expectation on maintaining feature parity with those mature interfaces, and surprise hot plug is the one feature that trips up testing most often. This is not surprising as many software and hardware components that were previously not in the storage hot plug path need to come together to harmoniously work in any given situation. This presentation will explain the most recent software and hardware enhancements to handle corner case and error conditions, as well as remaining gaps and limitations.
