Abstract: Methods and systems to provide a form of probabilistic labeling to associate an outage with a disturbance, which could itself be either known based on the available data or unknown. In the latter case, labeling is especially challenging, as it necessitates the discovery of the disturbance. One approach incorporates a statistical change-point analysis to time-series events that correspond to service tickets in the relevant geographic sub-regions. The method is calibrated to separate the regular periods from the environmental disturbance periods, under the assumption that disturbances significantly increase the rate of loss-causing events. To obtain the probability that a given loss-causing event is related to an environmental disturbance, the method leverages the difference between the rate of events expected in the absence of any disturbances (baseline) and the rate of actually observed events. In the analysis, the local disturbances are identified and estimators of their duration and magnitude are provided.

Abstract: Memory management processes allocate and recycle pages of replication data pointer (RDP) metadata space in shared memory. When the RDP page currently allocated to an IO thread becomes full, that RDP page is released, and a new RDP page is allocated to the IO thread. The released page eventually becomes fragmented and is added to a list of RDP pages that are ranked based on partial fullness. An IO thread that needs a new RDP page is allocated a mostly empty RDP page from the ranked list, if such a page is available. Otherwise, a new completely empty RDP page is allocated to the IO thread. Use of the ranked lists reduces latency associated with allocation of new RDP pages. Contention between IO threads for RDP metadata space is reduced because each IO thread has exclusive rights to the free RDP metadata space in its currently allocated page.
