By Peter Onufryk, Management Workgroup Chair and Austin Bolen, Management Workgroup Vice Chair NVM Express® is innovating to effectively and efficiently service today’s data-intensive storage demands. The NVMe open collection of standards reveal the scores of benefits of non-volatile memory in all types of computing environments from mobile to data centers. Enterprise IT, storage and [...]
By Janene Ellefson, NVM Express Marketing Workgroup Co-Chair Deemed “the new language of storage,” NVM Express® saw a year of recognition and implementation in 2018, with more than 100 companies offering NVMe™ or enabled products. Looking forward to 2019, NVMe is not expected to plateau; in fact, most analysts and industry experts anticipate this will be the year [...]
By Jonmichael Hands, NVM Express Marketing Co-Chair 2018 was a huge year for NVMe™. NVMe SSD shipments now make up the majority of SSD revenue and capacity shipments, and some analysists are showing that the industry average ASP of NVMe is now equivalent of SATA, driven by hyperscale deployments. It was also a huge year [...]
NVMe Management Interface Architectural Overview NVMeTM Management Interface (NVMe-MITM) is targeted at enterprise and hyperscale applications and currently not at client applications. The use cases include: Inventorying (Asset Management), Health Monitoring (Identify bad drives), Wear Monitoring (Replace drives nearing wear-out), Temperature Monitoring (Fan throttling), Power Monitoring and configuration, Configuring (format drives, crypto erase), Change Management (update [...]
NVMe Specification Readiness NVM Express® is an open collection of standards and information and the NVM Express organization (www.nvmexpress.org) is responsible for specifying the NVMe specifications. To date (August 2018) it has released several specifications: Base NVMe Specifications including NVMe 1.0e, 1.2.1 and 1.3 NVMeTM Over Fabric 1.0 Specification and NVMeTM Management Interface 1.0 Specification [...]
NVMe Over Fabrics Architectural Overview NVMeTM Over Fabrics replaces the PCIe transport with a fabric technology such as RDMA or Fibre Channel (FC) fabric as shown in Figure 3. Transports for RDMA fabric include Ethernet (ROCE), InfiniBand and iWARP. Native TCP (non-RDMA) transport is also possible (TCP is still Work-In-Progress as of July 2018). Figure 3: [...]
Written by Murali Rajagopal, PhD- VMware Storage Architect, Office of the CTO There is much in the way of NVMe ExpressTM (NVMeTM) literature publicly available especially surrounding SSDs – mainly originating from device manufacturers. This blog provides a grand overview of the NVM ExpressTM technology, the eco-system, NVM ExpressTM specifications, devices and interfaces. It is [...]

Authors: Sagi Grimberg, Chief SW Architect, Lightbits Labs and Dave Minturn, Intel Corp., Fabrics Linux Driver WG Chair This week the ratified NVMe™/TCP Transport Binding specification has been made available for public download. TCP is a new transport added to the family of existing NVMe™ transports; PCIe®, RDMA, and FC. NVMe/TCP defines the mapping of [...]
By Brandon Hoff I recently presented a webcast on NVM Express® over Fabrics (NVMe-oF™) and gave a rundown on what’s new for NVMe-oF in 2018. Since the NVMe-oF specification’s official release in May 2016, we have seen a lot of excitement building. In my webcast, I deliver a high-level overview of the NVMe-oF content we [...]
