The NVM Express® (NVMe®) specifications define how host software communicates with non-volatile memory across multiple transports like PCI Express® (PCIe®), RDMA, TCP and more. It is the industry standard for solid state drives (SSDs) in all form factors (U.2, M.2, AIC, EDSFF).

2025年3月17日 · Designed from the ground up for SSDs, the NVM Express® (NVMe®) base specification was initially created to help define how host software communicates with non-volatile memory across a PCI Express® (PCIe®) bus.

NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface specification for accessing a computer's non-volatile storage media usually attached via the PCI Express bus.

2020年9月21日 · The NVM Express base specification revision 1.4 and prior revisions defined a register level interface for host software to communicate with a non-volatile memory subsystem over PCI Express (NVMeTM over PCIeTM). The NVMeTM over Fabrics specification defines a protocol interface and related extensions to the

Usage of this Specification is governed by the terms and conditions set forth in the Open Web Foundation Final Specification Agreement (“OWFa 1.0”). Note: The following clarifications, which distinguish technology licensed in the Contribution License

NVMe technology provides superior storage, superior speed and superior compatibility. Because NVMe utilizes PCIe sockets, it transfers 25x more data than the SATA equivalent. Along with more data, NVMe’s commands are 2x faster than that of AHCI drivers.

This document is to define the requirements for a cloud based NVMeTM SSD for use in data centers. This document covers PCIe-attached SSDs using NVM Express. The device shall comply with all required features of the NVMe 1.4 specification. Optional features shall be implemented per the requirements of this specifications.

NVMe (non-volatile memory express) is a transfer protocol created to accelerate the transfer speed of data in solid-state storage devices. NVMe is used in both enterprise and client systems.

2024年10月18日 · The latest NVMe specs consist of multiple documents targeted at allowing faster and simpler development of NVMe architecture. The 3 new specs are the NVMe Boot specification, the Subsystem Local Memory command …

2022年1月4日 · The NVMe 2.0 specification, published in June 2021, introduced changes to improve performance and to support new uses of NVMe. While NVMe originally supported only block storage, which was the way that storage had always worked in the past, NVMe 2.0 provides two Command Set upgrades to add Zoned Namespaces (ZNS) and Key Value support.
