Efficiently transferring data between tiers in a virtual storage system, including: receiving, by the virtual storage system, a request to write data to the virtual storage system; transforming, within storage provided by a first tier of storage of the virtual storage system, the data to generate transformed data; and migrating, from the first tier of storage to a second tier of storage that is more durable than the first tier of storage of the virtual storage system, at least a portion of the transformed data.

Container images are managed in a clustered container host system with a shared storage device. Hosts of the system each include a virtualization software layer that supports execution of virtual machines (VMs), one or more of which are pod VMs that have implemented therein a container engine that supports execution of containers within the respective pod VM. A method of deploying containers includes determining, from pod objects published by a master device of the system and accessible by all hosts of the system, that a new pod VM is to be created, creating the new pod VM, and spinning up one or more containers in the new pod VM using images of containers previously spun up in another pod VM, wherein the images of the containers previously spun up in the other pod VM are stored in the storage device.

Technologies for allocating resources of managed nodes to workloads to balance multiple resource allocation objectives include an orchestrator server to receive resource allocation objective data indicative of multiple resource allocation objectives to be satisfied. The orchestrator server is additionally to determine an initial assignment of a set of workloads among the managed nodes and receive telemetry data from the managed nodes. The orchestrator server is further to determine, as a function of the telemetry data and the resource allocation objective data, an adjustment to the assignment of the workloads to increase an achievement of at least one of the resource allocation objectives without decreasing an achievement of another of the resource allocation objectives, and apply the adjustments to the assignments of the workloads among the managed nodes as the workloads are performed. Other embodiments are also described and claimed.

The present disclosure describes apparatuses and methods for automatically mapping virtual functions to storage media to enable single root input output virtualization. A storage media switch manages access to virtual functions that execute behind a storage media interface managed by the switch. The switch includes a host interface through which the switch receives host commands. The switch determines virtual function identifiers associated with the host commands and automatically selects the virtual functions of the storage media based on the virtual function identifiers. The switch executes the host commands over the storage media interface using the virtual functions, and after execution, responds via the host interface to each of the host commands. By automatically mapping virtual functions in this way, the switch automatically enables single root input output virtualization of storage media, including storage media that is without native support for input output virtualization.

Systems, methods and apparatus of intelligent bandwidth allocation to different types of operations to access storage media in a data storage device. For example, a data storage device of a vehicle includes: storage media components; a controller configured to store data into and retrieve data from the storage media components according to commands received in the data storage device; and an artificial neural network configured to receive, as input and as a function of time, operating parameters indicative a data access pattern, and generate, based on the input, a prediction to determine an optimized bandwidth allocation scheme for controlling access by different types of operations in the data storage device to the storage media components. The controller is configured to schedule the operations of the different types to access the one or more storage media components according to the optimized bandwidth allocation scheme.

Disclosed deduplication techniques at a distributed data storage system guarantee that space reclamation will not affect deduplicated data integrity even without perfect synchronization between components. By understanding certain “behavioral” characteristics and schedule cadences of backup operations that generate backup copies received at the distributed data storage system, data blocks that are not re-written by subsequent backup copies are pro-actively aged, while promoting continued retention of data blocks that are re-written. An expiry scheme operates with block-level granularity. Each unique deduplicated data block is given an expiry timeframe based on the block's arrival time at the distributed data storage system (i.e., when a backup copy supplies the block) and further based on backup frequencies of the various virtual disks referencing a unique system-wide identifier of the block, which is based on the block's hash value. Communications between components are kept to an as-needed basis. Cloud-based and multi-cloud configurations are disclosed.

Administering storage access in a cloud-based storage system includes: acquiring, by a first storage controller, in response to a protocol request for exclusive access to an area of storage, a first lease for the area of storage of the cloud-based storage system; and storing, by the first storage controller, a first identifier for the first lease in a predefined portion of the area of storage, where the predefined portion of the area of storage is accessible to a second storage controller.

A storage device for providing data storage services to a source host and a destination host includes persistent storage and a controller. The controller obtains a handoff initiation request for a handoff of storage resources of the persistent storage allocated to the source host, the handoff initiation request specifies that the storage resource is to be handed off to the destination host; in response to obtaining the handoff initiation request: quiesces the storage resource; terminates use of the storage resource by the source host after quiescing the storage resource; after terminating the use of the storage resource by the source host, connects the destination host to the storage resource; and after connecting the destination host to the storage resource, enables use of the storage resource by the destination host.

Aspects of the present disclosure relate to improving response rates of input/output (IO) requests targeting undefined virtual storage devices. In embodiments, an (IO request can be received by a storage array. Additionally, a determination of whether the IO request targets an undefined target track can be made. Further, source data related to the IO request can be located. For instance, a direct image lookup (DIL) can be performed to locate the source data. Also, a storage-related operation on the undefined target track can be performed using instructions provided by the IO request, such as updating a version of the undefined track. Further, a storage resource allocation for the undefined target track can be destaged.

A method includes: receiving, by a storage device from a core in a host, a request to provide exclusive resource to a command of a predefined submission queue of a non-volatile memory (NVM) set in the storage device, wherein the request pertains to operating the NVM set in a deterministic state; generating a virtual NVM set identifier for a virtual NVM set based on a predefined mapping of the predefined submission queue and the NVM set; determining a storage controller associated with the NVM set based on a predefined mapping of the predefined submission queue, the NVM set, and the virtual NVM set identifier; enabling at least one core to operate in a Predictable Latency Mode; and operating the storage controller and the NVM set in the deterministic state by allocating predetermined resources to execute the command and return data with a predictable latency.
