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,… Read More

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… Read More

The NVMe protocol allows servers or storage systems to communicate to flash storage with more optimally. This PCIe-based architecture enables larger command sets and IO queue depths resulting in lower latency and greater performance. It is a wholesale replacement for SCSI. But there is another SCSI protocol lurking in the… Read More

This is another one of those geeky stories that actually has some significance. The Non-Volatile Memory (NVM) Express group has issued version 1.3 of its SSD spec, with emphasis on performance around analytics and virtualization. NVMe is a communications interface/protocol designed specifically for solid-state drives (SSDs) because the old standard,… Read More
