Abstract: The disclosed technology relates to determining physical zone data within a zoned namespace solid state drive (SSD), associated with logical zone data included in a first received input-output operation based on a mapping data structure within a namespace of the zoned namespace SSD. A second input-output operation specific to the determined physical zone data is generated wherein the second input-output operation and the received input-output operation is of a same type. The generated second input-output operation is completed using the determined physical zone data within the zoned namespace SSD.

Abstract: Methods, non-transitory machine readable media, and computing devices that dynamically throttle non-priority workloads to satisfy minimum throughput service level objectives (SLOs) are disclosed. With this technology, a determination is made when a number of detection intervals with a violation within a detection window exceeds a threshold, when a current one of the detection intervals is outside an observation area. The detection intervals are identified a violated based on an average throughput for priority workloads within the detection intervals exceeding a minimum throughput SLO. A throttle is then set to rate-limit non-priority workloads, when the number of violated detection intervals within the detection window exceeds the threshold. Advantageously, throughput for priority workloads is more effectively managed and utilized with this technology such that throttling oscillations are reduced, throttling is not deployed in conditions in which it would not improve throughput, and throttling is minimally deployed to maximize throughput.

Abstract: A technique is configured to provide various data protection schemes, such as replication and erasure coding, for data blocks of volumes served by storage nodes of a cluster configured to perform deduplication of the data blocks. Additionally, the technique is configured to ensure that each deduplicated data block complies with data redundancy guarantees of the data protection schemes, while improving storage space of the storage nodes. In order to satisfy the data integrity guarantees while improving available storage space, the storage nodes perform periodic garbage collection for data blocks to optimize storage in accordance with currently applicable data protection schemes

Abstract: A technique is configured to provide data protection, such as replication and erasure coding, of content driven distribution of data blocks served by storage nodes of a cluster. When providing data protection in the form of replication (redundancy), a slice service of the storage node generates one or more copies or replicas of a data block for storage on the cluster. Each replicated data block is illustratively organized within a bin that is maintained by block services of the nodes for storage on storage devices. When providing data protection in the form of erasure coding, the block services may select data blocks to be erasure coded. A set of data blocks for erasure coding may then be grouped together to form a write group. According to the technique, EC group membership is guided by varying bin groups so the data is resilient against failure. Slice services of the storage nodes assign data blocks of different bins and replicas to a write group.

Abstract: A technique is configured to utilize frames generated by a first layer of a protocol stack for a first network to configure network parameters associated with a second layer of the protocol stack for a second network. The frames are illustratively beacon frames generated by a data link layer of a Transmission Control Protocol/Internet Protocol (TCP/IP) stack for a wireless network, and the network parameters are illustratively IP addresses associated with a network layer of the TCP/IP stack for a wired network. Notably, the beacon frames of the wireless network may be utilized for two-way communication exchange on a per node basis for each node in the wired network.

Abstract: Techniques are provided for providing a storage abstraction layer for a composite aggregate architecture. A storage abstraction layer is utilized as an indirection layer between a file system and a storage environment. The storage abstraction layer obtains characteristic of a plurality of storage providers that provide access to heterogeneous types of storage of the storage environment (e.g., solid state storage, high availability storage, object storage, hard disk drive storage, etc.). The storage abstraction layer generates storage bins to manage storage of each storage provider. The storage abstraction layer generates a storage aggregate from the heterogeneous types of storage as a single storage container. The storage aggregate is exposed to the file system as the single storage container that abstracts away from the file system the management and physical storage details of data of the storage aggregate.

Abstract: A method, non-transitory computer readable medium, and device that assists with performing data deduplication on data blocks includes receiving a plurality of data blocks, wherein each of the received plurality of data blocks are of an equal memory size. Each of the received plurality of data blocks are split into a plurality of segments with a segment size less than the equal memory size. Duplicate data is identified within each of the plurality of segments for each of the received plurality of data blocks. One occurrence of the identified duplicate data is stored from each of the received plurality of data blocks into a new data block.

Abstract: One or more techniques and/or computing devices are provided for cross- platform replication. For example, a replication relationship may be established between a first storage endpoint and a second storage endpoint, where at least one of the storage endpoints, such as the first storage endpoint, lacks or has incompatible functionality to perform and manage replication because the storage endpoints have different storage platforms that store data differently, use different control operations and interfaces, etc. Accordingly, replication destination workflow, replication source workflow, and/or a proxy representing the first storage endpoint may be implemented at the second storage endpoint comprising the replication functionality. In this way, replication, such as snapshot replication, may be implemented between the storage endpoints by the second storage endpoint using the replication destination workflow, the replication source workflow, and/or the proxy that either locally executes tasks or routes tasks to the first storage endpoint such as for data access.

Abstract: One or more techniques and/or computing devices are provided for secure data replication. For example, a first storage controller (116) may host first storage (128) within which storage resources (e.g., files, logical unit numbers (LUNs), volumes, etc.) are stored. The first storage controller (116) may establish an access policy with a second storage controller (118) to which data is to be replicated from the first storage (128). The access policy may define an authentication mechanism for the first storage controller (116) to authenticate the second storage controller (118), an authorization mechanism specifying a type of access that the second storage controller (118) has for a storage resource, and an access control mechanism specifying how the second storage controller's access to data of the storage resource is to be controlled. In this way, data replication requests may be authenticated and authorized so that data may be provided, according to the access control mechanism, in a secure manner.
