The NVMe-oF specification has been absorbed into the NVMe 2.0 library of specifications. It has become a part of the Base specification, TCP/IP specification and RDMA specification.
The NVMe-oF 1.1 specification included several framework improvements to make NVMe-oF implementations easier. These improvements included enhanced discovery features, officially defined in ratified Technical Proposal (TP) 8002. This TP added persistent controller support for discovery to notify hosts when the fabric configuration changes. NVMe-oF 1.0 discovery offered the following capabilities: The ability to discover a [...]
NVMe technology can be transported by all popular networks. iWarp has been optimized for WAN so NVMe can 'travel' outside of the Data Center.
The NVM Express specification is built so that it can be utilized across multiple transports beyond PCI Express architecture, including Ethernet, Fibre Channel, Infiniband and RDMA.
