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 [...]

Flash storage can sure live up to its name, but there's always room for speed improvements, particularly in the data center.

A few years ago, for the readers of Storage Insiders, it became apparent that future SSDs would not end their lifecycle on a SAS, let alone a SATA interface

An optimally-running data center must have a storage protocol (a standard for storage software, features and so on) and a hardware interface that is developed and tuned for the media device.

NVMe has quickly become the storage medium of choice for high performance applications.

The first step for NVMe flash is to use them internally in servers and storage systems.

There are three points within the storage infrastructure that will use NVMe; internal to the storage system, intra-connectivity between storage systems and inter-connectivity to physical servers.
