NVM ExpressTM (NVMeTM) Base Specification revision 1.4 and prior revisions define a register level interface for host software to communicate with a non-volatile memory subsystem over PCI ExpressTM (NVMeTM over PCIeTM ). This specification defines extensions to NVMe that enable operation over other interconnects (NVMeTM over Fabrics). The NVM Express Base Specification revision 1.4 is referred to as the NVMe Base specification. The mapping of extensions defined in this document to a specific NVMe Transport are defined in an NVMe Transport binding specification. This document contains an NVMe Transport binding specification for RDMA and TCP. The NVMe Transport binding specification for Fibre Channel is defined in INCITS 540 Fibre Channel – Non-Volatile Memory Express (FC-NVMe), refer to http://www.incits.org.
