Abstract: Techniques are provided for managing objects within an object store. An object is maintained within an object store. The object comprises a plurality of slots. Each slot is used to store a unit of data accessible to applications hosted by remote computing devices. The object comprises an object header used to store metadata for each slot. A determination is made that the object is a fragmented object comprising an in-use slot of in-use data and a freed slot from which data was freed. The object is compacted to retain in-use data and exclude freed data as a rewritten object.

Abstract: Techniques are provided for overlapping write handling. Overlapping write managers are used to maintain the order that write operations are executed at a first computing environment and replicated to a second computing environment. Overlapping write managers are pre-allocated as available for managing overlapping write operations. A mapping is used to track what overlapping write managers are currently allocated for particular file handles of files. Thus, if an incoming write operation targets a file handle of an already allocated overlapping write manager, then that overlapping write manager is used to execute and replicate the incoming write operation so that the order of execution of overlapping writes by the second computing environment is the same as at the first computing environment. If there is no allocated overlapping write manager for the file handle, then a new overlapping write manager is allocated and utilized.

Abstract: Methods and systems for executing code are provided. A message with executable code is received by a processor that utilizes the message to generate a key associated with a value having executable code stored at a key-value store. The processor retrieves the value from the key-value store using the generated key. The processor then merges the executable code in the received message and the executable code in the retrieved value to generate a merged value for code execution.

Abstract: One or more techniques and/or systems are provided for profiling a dataset. For example, a snapshot of a volume may be evaluated to identify a set of data characteristics, such as file and directory size information. A baseline dataset profile of a dataset of data within the volume may be constructed based upon the set of data characteristics. Histograms and graphs of directory counts and file counts may be constructed based upon the baseline dataset profile. An incremental dataset profile may be constructed for the dataset based upon an evaluation of the snapshot and a subsequent snapshot of the volume. Histograms and graphs of directories and files that are modified, created, and/or deleted may be constructed based upon the incremental dataset profile. Performance predictions, analytics, field diagnostics of performance issues, and/or scheduling of service execution may be implemented for a storage network hosting the volume based upon dataset profiles.

Abstract: A technique is configured to utilize messages (e.g., frames) generated by a first layer of a protocol stack for a wireless network to configure network parameters associated with a second layer of the protocol stack for a wired network. The messages 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: Computing technology for managing support requests are provided. The technology includes a processor executable application programming interface (API) that receives a support case indicating a problem associated with a device. The API utilizes a training model to predict a problem category for the support case. The training model predicts the problem category based on a feature extracted from information included in the support case. The training model further identifies a plurality of proximate support cases based on a distance between the support case and the proximate support cases within a virtual space assigned to the predicted problem category; determines relevance of each proximate support case to the support case; and outputs a resolution code for the support case based on the determined relevance of each proximate support case.

Abstract: A request is received to retrieve at least a portion of a file from a compressed data archived image stored in a backup storage device. The compressed data archived image comprises a backup of a file system having a number of directories and a number of files. The compressed data archived image comprises a file that includes a compression of the number of files. An address of the at least the portion of the file within the compressed data archived image is determined. The at least the portion of the file is retrieved at the address in the compressed data archived image, without decompressing the compressed data archived image.

Abstract: Various embodiments are directed to techniques for dynamically adjusting a maximum rate of throughput for accessing data stored within a volume of storage space of a storage cluster system based on the amount of that data that is stored within that volume. An apparatus includes an access component to monitor an amount of client data stored within a volume defined within a storage device coupled to a first node, and to perform a data access command received from a client device via a network to alter the client data stored within the volume; and a policy component to limit a rate of throughput at which at least the client data within the volume is exchanged as part of performance of the data access command to a maximum rate of throughput, and to calculate the maximum rate of throughput based on the stored amount.

Abstract: Techniques are provided for synchronous replication based cutover. An asynchronous replication process is executed to perform asynchronous incremental transfers of data of a storage object from a first computing environment to a replicated storage object at a second computing environment until a cutover criteria is met. A synchronous replication process is executed to synchronously replicate operations, targeting the storage object, to the replicated storage object based upon the cutover criteria being met. A cutover is performed to direct operations from targeting the storage object to targeting the replicated storage object based upon the synchronous replication process reaching a steady state of synchronous replication for sub-objects of the storage object, where operations are committed to both the storage object and the replicated storage object.
