16G PowerEdge servers | Dell PowerEdge 16th generation servers |
Arrays | Dell PowerStore storage arrays |
BFS | Boot from SAN |
NVMe host | An entity that interfaces to an NVM subsystem through one or more controllers and submits commands to Submission Queues and retrieves command completions from Completion Queues. A server host typically is an NVMe host, in that it initiates NVMe-oF connections to make use of a disk storage resource provided by a storage array. |
NVMe Qualified Name (NQN) | NQNs are used to uniquely describe a host or NVM subsystem for the purposes of identification and authentication. |
Storage Area Network (SAN) | A network that connects storage arrays and host interfaces. A SAN often includes arrays, switches, and host interconnections as a single entity. |
NVM subsystem | An NVM subsystem includes one or more domains, one or more controllers, zero or more namespaces, and one or more ports. Typically, a PowerStore array is an NVM subsystem providing namespaces for the host to boot from. |
Controller | A controller is the interface between a host and an NVM subsystem. A discovery controller exposes capabilities that allow a host to retrieve a Discovery Log Page for I/O controllers usually. An I/O controller implements I/O queues and is intended to be used to access a nonvolatile memory storage medium. |
