When a compute node is connected to the storage via NVMe/TCP, VSP One SDS Block automatically creates NVM device control information (NVM subsystems and namespaces) for the storage (target) side.
The following shows an example of system configuration when NVMe/TCP connection is used.
One NVM subsystem is created in the VPS. The NVM subsystem is automatically created when the first compute node is registered in the VPS, and is automatically deleted when the last compute node in the VPS is deleted.
For details about registering and deleting compute nodes, see Registering information about compute nodes and Deleting information about compute nodes.
One namespace is created for each volume in the NVM subsystem. The namespace is automatically created when the first volume path for a volume is set, and is automatically deleted when the last volume path for the volume is deleted.
For details about setting and deleting volume paths, see Allocating volumes to compute nodes and Canceling allocation of volumes to compute nodes.
