NVMe protocol

You can use Storage Manager to configure the NVMe protocol. The NVMe is a transport protocol that provides high speed access to flash-based network storage. Systems that use NVMe protocol have a subsystem consisting of specific NVME controllers, namespaces, nonvolatile storage medium, hosts, ports and and interface between the controller and storage medium.

  • Setting up NVMe
    You can set up the NVMe protocol for an SVM using Storage Manager . When the NVMe protocol is enabled on the SVM, you can then provision a namespace or namespaces and assign them to a host and a subsystem.
  • Creating an NVMe namespace
    You can use Storage Manager to create one or more NVMe namespaces and connect each to a host or set of hosts in a storage virtual machine (SVM). The NVMe namespace is a quantity of memory that can be formatted into logical blocks. Each namespace can be mapped to an NVMe subsystem.
  • Editing an NVMe namespace
    You can use Storage Manager to edit the namespace by changing the subsystem that the namespace is mapped to.
  • Cloning an NVMe namespace
    You can use Storage Manager to quickly create another namespace of the same configuration by choosing to clone a namespace. You can map the newly cloned namespace to another host NQN.
  • Starting and stopping the NVMe service
    The NVMe service enables you to manage NVMe adapters for use with namespaces. You can use Storage Manager to start the NVMe service to bring the adapters online. You can stop the NVMe service to take the NVMe adapters offline and to disable access to the namespaces.
  • What NVMe is
    The nonvolatile memory express (NVMe) protocol is a transport protocol used for accessing nonvolatile storage media.
  • NVMe namespaces
    An NVMe namespace is a quantity of non-volatile memory (NVM) that can be formatted into logical blocks. Namespaces are used when a storage virtual machine is configured with the NVMe protocol and are the equivalent of LUNs for FC and iSCSI protocols.
  • What an NVMe subsystem is
    An NVMe subsystem includes one or more controllers, one or more namespaces, one or more non-volatile memory (NVM) subsystem ports (FC-NVMe or RDMA transport ports), an NVM storage medium, and an interface between the controllers and the NVM storage medium. For controller mapping and management, an NVM subsystem maps to a vserver in ONTAP.
  • NVMe namespaces
    An NVMe namespace is a quantity of non-volatile memory (NVM) that can be formatted into logical blocks. Namespaces are used when a storage virtual machine is configured with the NVMe protocol and are the equivalent of LUNs for FC and iSCSI protocols.
  • NVMe namespaces window
    You can use the NVMe namepaces window to set up and manage your namespaces and associated subsytems for the NVMe protocol. You can search for an existing namespace using the namespace path.
