Abstract: An apparatus in an illustrative embodiment comprises at least one processing device that includes a processor coupled to a memory. The at least one processing device is configured to associate a logical storage volume with at least one path between a host and at least a given one of a plurality of storage nodes of a distributed storage system, and to associate a proxy volume with respective sets of one or more paths from the host to each of the plurality of storage nodes of the distributed storage system. The at least one processing device is further configured to obtain an input-output operation directed to the logical storage volume, and to redirect the input-output operation to the proxy volume over a selected one of the paths associated with the proxy volume. Such an arrangement can avoid one or more host-side restrictions, thereby enhancing scalability of the distributed storage system.

Abstract: A method is disclosed of copy-free, non-disruptive conversion of a storage volume from a first access protocol to a distinct second access protocol. In a preparatory step a destination volume accessible according to the second access protocol is created. A pairing of a token and a handle is created, the token representing data content of the source volume, the handle being associated with the token and usable to represent the source volume according to the second protocol. In response to a subsequent copy-with-handle command, and based on the pairing of the handle with the token, metadata of the destination volume is populated to reference, without copying, the underlying stored data, the destination volume thereafter functioning as the storage volume accessed using the second protocol.

Abstract: Embodiments presented herein enable non-volatile memory express (NVMe®) subsystem-driven commands. By configuring subsystems as pull model devices, subsystems can request a centralized discovery controller to perform Send Log Page commands, include Host Discovery. Embodiments may leverage a command execution request architecture to achieve the subsystem-driven Send Log Page commands.

Abstract: A command is received from a host regarding accessing an NVMe dispersed namespace in a metro cluster configuration of storage arrays. A namespace group state corresponding to the host and the port is determined and returned to the host. The namespace group state indicates whether the specific communication path between the host and the port is optimized or non-optimized. The namespace group state indicates that the communication path is non-optimized where the host is not located at the same location as the storage array, and that the communication path is optimized where the host is located at the same location as the storage array and the node of the storage array is a preferred node for processing I/O directed to the NVMe dispersed namespace from hosts located in the same location as the storage array.

Abstract: Discovery service contact information is provided from a data storage system to administration logic of a virtualization environment, and distributed within the virtualization environment to hypervisor hosts, enabling the hypervisor hosts to discover logical ports within the data storage system, and then establish logical communication paths between the hypervisor hosts and the ports. In response to determining that the data storage system supports virtual volumes, the hypervisor hosts indicate hypervisor capability of using virtual volumes to the data storage system, and the data storage system exposes virtual volumes to hypervisors in response to indications of the ability of those hypervisors to use virtual volumes.

Abstract: A method, computer program product, and computing system for defining a vVol NVMe subsystem for a plurality of vVol NVMe namespaces within a storage system; and enabling an Asymmetric Namespace Access (ANA) group that aggregates two or more vVol NVMe namespaces defined within the plurality of vVol NVMe namespaces and communicates ANA group information in-band, thus eliminating the need for out-of-band communication of vVol protocol endpoint information.

Abstract: A data storage system (DSS) in a cluster provides virtual-volume data storage to virtual-computing (VC) hosts using NVMe-oF storage interconnect. A DSS creates protocol endpoints (PEs) and corresponding namespace groups, each being a grouping of namespaces corresponding to virtual volumes (vVols) to be bound for access by a respective VC host, and each namespace being mapped to corresponding underlying physical storage. Each namespace group is initially created with a corresponding in-band discoverable dummy namespace. In response to in-band storage discovery commands from the VC hosts, and based on the existence of the dummy namespaces, the DSS responds with responses identifying the namespace groups. Then in response to subsequent vVol creation commands from the VC hosts, the DSS creates new namespaces in respective namespace groups and provides namespace identifiers for the new namespaces to the VC hosts for use in accessing data of the vVols.

Abstract: Transferring an application from a first site to a second site includes determining that the second site is a destination site for the application, causing writes by the application at the first site to be propagated synchronously to the second site, transferring storage data from the first site to the second site, suspending operation of the application on the first site, and resuming operation of the application on the second site. The application may be a virtual machine or a host cluster capable of transitioning applications between cluster nodes. The virtual machine may be transferred from the first site to the second site by transferring an image of the virtual machine from the first site to the second site. The destination site may be selected by a user. The second site may be located remotely from the first site across an asynchronous distance.

Abstract: Described are techniques for automatically configuring target port settings. A set of target port settings of a target port of a data storage system is initialized in accordance with a first target port setting configuration. It is determined whether the data storage system supports host registration. If the data storage system supports host registration, first processing is performed that includes registering a first host with the data storage system, wherein registering includes sending first information from the first host to the data storage system, the first information being sent from an initiator port of the first host to the target port; determining, using the first information, whether the set of target port settings of the target port require modification for use by the first host; and modifying the set of target port settings in accordance with the first information if the set of target port settings require modification.
