A method for managing a storage system includes monitoring the storage system to obtain a set of input/output (I/O) telemetry entries, determine a workload signature based on the set of I/O telemetry entries, obtaining, based on the workload signature, a set of performance metrics, performing a parameter analysis to determine a set of alternative storage system parameterizations, based on the set of alternative storage system parameterization, generating a set of alternative performance metrics, updating a performance index structure based on the performance metrics, and the set of alternative performance metrics to obtain an updated performance index structure, and initiating a storage system update based on the updated performance index structure.

An apparatus comprises at least one processing device that is configured to control delivery of input-output operations from a host device to a storage system over selected ones of a plurality of paths through a network. The at least one processing device is further configured to detect a reduction in performance of one or more of the input-output operations over one or more paths of the plurality of paths, to identify a physical initiator component corresponding to the one or more paths, and to notify the storage system about the reduction in performance and the identified physical initiator component. The at least one processing device is also configured to receive a notification from the storage system indicating one or more virtual initiator instances of a plurality of virtual initiator instances corresponding to the identified physical initiator component, and to deactivate the one or more virtual initiator instances.

Methods and systems are provided for rapid failure recovery for a distributed storage system for failures by one or more nodes.

An apparatus includes operational circuitry and Hardware Diagnostics Circuitry (HDC). The HDC is configured to receive a definition of multiple trigger rules, each trigger rule specifying a respective trigger event as a function of trigger data sources in the operational circuitry, to receive a definition of (i) a pre-trigger logging set selected from among a plurality of diagnostics data sources in the operational circuitry, and (ii) for each trigger rule, a respective post-trigger logging set including a set of one or more of the diagnostics data sources, and, during operation of the operational circuitry, to log the diagnostics data sources in the pre-trigger logging set, to log the trigger data sources and to repeatedly evaluate the trigger rules, and, in response to triggering of a given trigger event by a given trigger rule, to start logging the diagnostics data sources in the post-trigger logging set of the given trigger rule.

An illustrative method includes a data protection system determining a delta metric between a first recovery dataset generated by a storage system at a first time and a second recovery dataset generated by the storage system at a second time subsequent to the first time and determining, based on the delta metric, whether data maintained by the storage system is possibly being targeted by a security threat.

An illustrative method includes a data protection system detecting, for a storage system, a potential data corruption in the storage system, analyzing, in response to the detecting of the potential data corruption, one or more metrics of the storage system, and determining, based on the analyzing of the one or more metrics of the storage system, a corruption-free recovery point for potential use to recover from the potential data corruption.

Embodiments of a system for determining a data gravity index score and implementing pervasive data center architecture is disclosed. In some embodiments, the system can calculate a data gravity index score based on the amount of data stored in a given location, an amount of data in motion in the given location, a bandwidth index associated with the given location, and a latency index associated with the given location. Based on data gravity index scores, in some embodiments, the system can localize traffic to improve network performance, improve security operations, and generate software-defined-network overlay.

A method begins by a dispersed storage (DS) processing module collecting an event record, a record regarding processing of an event request, and a plurality of records regarding processing of a plurality of sub-event requests to produce a collection of records. The event record includes information regarding an event, wherein the event is a user access operation or a system administrative operation initiated by a device affiliated with the DSN. The record regarding processing of the event request includes information regarding a dispersed storage (DS) processing module of the DSN processing the event request to produce the plurality of sub-event requests. The plurality of records regarding processing of the plurality of sub-event requests includes information regarding a plurality of DS units of the DSN processing the plurality of sub-event requests. The method continues with the DS processing module evaluating the collection of records to produce performance information regarding the DSN.

Described herein are techniques for automating media agent state management. For example, if a media agent is running poorly, then the media agent can be disabled and an alternate media agent can perform secondary copy job operations in place of the poorly running media agent. To determine whether a media agent is running poorly, a storage manager can determine whether the media agent has an anomalous number of failed jobs, pending jobs, and/or long running jobs and/or can determine whether the amount of resources used by the media agent is high or is increasing constantly, at a constant rate, or at a near constant rate.
