Local Management

  • The Discovery Controller (DEM) does not configure individual Targets/Subsystems – Individual Targets must be locally configured.
  • The DEM must be informed about Target Interfaces to connect to in order to query log-pages.
  • Subsystems must be defined to associate log-pages for distribution.

In-band Management

  • The DEM uses a designated NVMe-oF fabric interface to talk with Targets.
  • The DEM is configured with all Individual Target Endpoint Manager (DEM-EM) interfaces to connect to.
  • The DEM will then query Individual SC for physical fabric interface and NVMe device resources.
  • The DEM Administrator has the ability to assign individual Target resources to NVMe-oF Port ID and Subsystems/Namespaces.

Out-of-Band Management

  • The Out-of-Band management mode operates the same as In-band management mode however uses a RESTful interface to communicate with the DEM-EM.
