NVM Express protocol was designed to reduce delays in treatment, a group of companies - to improve the performance of solid state drives in particular. NVM Express protocol is naturally laid on the PCI Express bus and the corresponding SSD. Connecting via the PCI Express bus without any special tricks to maximum effect is realized only within a single rack.
Recently, the organization presented the NVM Express specification, which expand the NVM Express protocol work for popular network and server interfaces. So, we have seen the light specification NVM Express over Fabrics 1.0. Using the NVM Express over Fabrics 1.0 NVM Express protocol and all its advanced features will be available at the level of the data center, rather than individual PCs or shelving racks.
Specifications NVM Express over Fabrics 1.0 are based on the NVM Express 1.2 specifications. Underlying the NVM Express protocol layered architecture allow to transport a lot of different levels, than, in fact, used by the developers. Separately, it is reported that created software tools NVMe over Fabrics for Linux and tools for working with drivers.
It also reminded the organization that was recently published the final specification NVMe Management Interface 1.0. Using VDM or SMBus / I2C, allowed to obtain the characteristics of SSD controller, including monitoring data and firmware status.
