  • Patent number: 11218386
    Abstract: Techniques for managing support computing services in computing systems are disclosed. One example technique includes analyzing data representing a service ticket having data representing multiple messages exchanged between the user and a support entity of a support tier in the computing system. Based on the analysis, an interaction pattern in the multiple messages can be identified. The interaction pattern includes a sequence of words or phrases arranged in a chronological order. The method can further include determining whether the identified interaction pattern matches one or more interaction patterns corresponding to previously escalated service tickets and triggering a notification of the immediate escalation of the service ticket to another support entity in another support tier in response to determining that the interaction pattern matches one of the one or more interaction patterns corresponding to previously escalated service tickets.

  • Publication number: 20210405924
    Abstract: Example storage systems, storage devices, and methods provide proactive management of storage operations to, for example, beneficially minimize bottlenecking, latency, and other issues. An example system has a storage pool with a first storage device and a second storage device, and a processor configured to generate a storage request including a storage command, include a command processing time constraint in the storage request, send the storage request to the first storage device, and receive, from the first storage device, a proactive response including an estimation for an execution of the storage command by the first storage device based on the command processing time constraint. The processor may then select a fallback mechanism for executing the storage command based on the proactive response.

  • Publication number: 20210406070
    Abstract: Example storage systems, storage devices, and methods provide novel management of storage device compute operations using intermediate results, such as approximate or partial results, to optimize processing flow. An example system has a storage medium and a storage controller coupled to the storage medium that is configured to evaluate a processing capability of a storage device and determine, based on the processing capability, that only a portion of a multi-stage compute operation is completable within a requested processing timeframe. The storage processor may further be configured to determine and provide an intermediate result, which may include an approximation or a partial result of the multi-stage compute operation. The intermediate result may be used by a client to manage its own processing while it awaits a final processing result.

  • Publication number: 20210397352
    Abstract: Aspects of a multi-protocol storage device including a controller are provided which handle mode switches after a shutdown resulting in a large amount of unfinished work by phasing the work during and after initialization. The controller operates in a first mode such as an SD mode and a second mode such as a NVMe mode. In the event of a shutdown in the second mode resulting in unfinished work, the controller initializes in the first mode. During initialization, the controller determines whether a completion time for the unfinished work exceeds an initialization time in the first mode. When the completion time exceeds the initialization time, the controller performs a first portion of the work during initialization and postpones performance of at least a second portion of the unfinished work until after initialization. As a result, initialization timeouts in the first mode due to the unfinished work may be avoided.

  • Publication number: 20210382653
    Abstract: Methods and apparatus for predicting a future estimated host read access rate for variable bit rate (VBR) data streams that include Program Clock Reference (PCR) indicators or other playback clock synchronization values. The VBR data stream may be encoded, for example, as a Motion Picture Experts Group (MPEG)-transport stream (TS). In some examples, a data storage device with a non-volatile memory (NVM) array parses an MPEG-TS VBR data stream retrieved from the NVM array to identify PCRs. Using the PCRs, the device estimates the future host data access rate for additional portions of MPEG-TS VBR data not yet requested by the host. The data storage device may then adaptively adjust background (e.g. overhead) management operations such as garbage collection based on the future host data access rate.

  • Publication number: 20210382621
    Abstract: Aspects of a multi-protocol storage device including a memory and a controller are provided which allow for endurance and other storage requirements of a host to be maintained for different logical regions of memory without disruption due to protocol switching. The memory includes blocks that are each associated with a storage attribute such as high endurance, performance, or protection. While operating in a first mode such as NVMe, the controller receives a mapping of storage attributes to different logical regions and stores the mapping in memory. The controller also associates blocks to logical addresses based on the mapping. When the controller switches to a second mode such as SD in response to a host command, the controller reads the mapping from memory and similarly associates blocks to logical addresses based on the mapping in the second mode. Storage attributes thus remain applicable across modes when mapping and storing data.

  • Publication number: 20210377590
    Abstract: A storage system and method for media-based fast-fail configuration are provided. In one embodiment, the storage system aggregates elapsed time spent handling errors in parts of a media frame read from the memory of the storage system. The storage system compares the aggregated elapsed time to a threshold representing a total acceptable latency. If the aggregated elapsed time does not exceed the threshold, the storage system handles error(s) in other part(s) of the media frame read from the memory. However, if the aggregated elapsed time exceeds the threshold, the storage system sends an error to a host without handling error(s) in other part(s) of the media frame read from the memory. Other embodiments are provided.
