In this video from the 2015 OFS Developer’s Workshop, Dave Akerson from Intel presents: NVMe Introduction and Tutorial.
NVM Express is a specification for accessing solid-state drives (SSDs) attached through the PCI Express (PCIe) bus. “NVM” stands as an acronym for non-volatile memory, which is used in SSDs. As a logical device interface, NVM Express has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and mirroring the parallelism of contemporary CPUs, platforms and applications. By allowing parallelism levels offered by SSDs to be fully utilized by host’s hardware and software, NVM Express brings various performance improvements.
