NVM Express, Inc. consists of more than 60 companies from across the industry. NVM Express was formed as an industry association to define a new storage interface protocol, NVM Express, to enable the full performance potential provided by Non-Volatile Memory based storage technology, such as PCI Express® Solid State Drives in a standards based approach that enables broad ecosystem adoption and interoperability.
The NVM Express 1.0 specification was released on March 1, 2011. The NVM Express 1.0 specification provides a scalable interface that unlocks the potential of PCIe-based SSDs now and with headroom for the next decade. The interface efficiently supports multi-core architectures; ensuring thread(s) may run on each core with their own SSD queue and interrupt without any locks required. For Enterprise class solutions, NVM Express supports end-to-end data protection, security and encryption capabilities, as well as robust error reporting and management capabilities.
The NVM Express 1.1 specification was released on October 11, 2012. NVM Express 1.1 adds a new level of enterprise and client functionality. For Enterprises, the NVMe 1.1 specification adds features to enable multi-host usage models such as Multi-Path I/O and namespace sharing, enhanced reset capabilities, and a simplified reservations mechanism compatible with SCSI reservations increasing fault tolerance. For both Enterprise and Client platforms, the NVMe 1.1 specification adds autonomous transitions during idle time to reduce platform power consumption.
The NVM Express 1.2 specification was released on November 3, 2014. NVM Express1.2 adds features for both enterprise and client systems. For client systems, additions include enhanced power management and other mobile oriented capabilities, such as a feature that supports designing high performance SSDs without local DRAM. This reduces SSD costs and enables smaller BGA (Ball Grid Array) based form factors. These features allow the compelling performance of NVMe to be used in solutions like fan-less two-in-one laptops. For enterprises, there are expanded capabilities including live firmware updates and a feature that provides reduced latency when many NVMe devices are used in an environment with one or more PCIe switches.
NVM Express specifications are owned and maintained by NVM Express, Inc. NVM Express, Inc. promotes industry awareness of NVM Express as an industry-wide standard to enable broad adoption and storage device interoperability.
NVM Express, Inc. is directed by a thirteen-member Board of Directors selected from the Promoter group. The Promoter Group includes Cisco, Dell, EMC, Intel, Micron, Microsemi, Microsoft, NetApp, Oracle, Samsung, SanDisk, Seagate and Western Digital.
