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 [...]
