Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.

A method of detecting anomalous latencies in communications between components on an integrated circuit (IC) chip. The method includes: (i) monitoring communications between a first component of the IC chip and other components of the IC chip, each communication comprising a command sent from the first component to another component, and a response received by the first component from that other component, the monitoring comprising: measuring the number of communications in each of a series of monitored time windows, and measuring the latency of each communication in the series of monitored time windows; (ii) calculating a maximum tolerable latency for each operational time window of the first component from the number of communications in that operational time window, an available stall time of the first component in that operational time window, and a latency penalty factor for that operational time window; and (iii) determining a measured latency to be anomalous if the measured latency is greater than the maximum tolerable latency.

A method of identifying a cause of an anomalous feature measured from system circuitry on an integrated circuit (IC) chip, the IC chip comprising the system circuitry and monitoring circuitry for monitoring the system circuitry by measuring features of the system circuitry in each window of a series of windows, the method comprising: (i) from a set of windows prior to the anomalous window comprising the anomalous feature, identifying a candidate window set in which to search for the cause of the anomalous feature; (ii) for each of the measured features of the system circuitry: (a) calculating a first feature probability distribution of that measured feature for the candidate window set; (b) calculating a second feature probability distribution of that measured feature for window(s) not in the candidate window set; (c) comparing the first and second feature probability distributions; and (d) identifying that measured feature in the timeframe of the candidate window set as a cause of the anomalous feature if the first and second feature probability distributions differ by more than a threshold value; (iii) iterating steps (i) and (ii) for further candidate window sets from the set of windows prior to the anomalous window; and (iv) outputting a signal indicating those measured feature(s) of step (ii)(d) identified as a cause of the anomalous feature.
