    摘要: Bulk synchronization reconciling maintains data volumes at the same version in redundant data storage libraries. Tokens of each library describe version-related characteristic(s) of an associated volume of data. At least one director establishes a reconcile set of tokens of the libraries describing dissimilar version-related characteristics of a same associated volume. A plurality of subsets of the reconcile set of tokens are established based on a first criteria, and allotted to directors to reconcile the data of volumes of the subsets, to split the reconciling between the directors. An example is to select subsets based on the last binary digit of the volume identifier, e.g. odd and even numbered subsets. Alternatively, the volume identifiers may be split into upper and lower halves. Further, the directors reconcile in a sequence based on a second criteria, e.g., one in numerical sequence, and another in reverse numerical sequence.

    摘要: A communication-path management system includes a path-detection component for identifying all communications paths between a host computer, through a controller, to a data storage device. Once identified, the communication paths are incorporated into a logical-path mask. The path-detection component recognizes each path as either preferred or non-preferred based on latency, bandwidth, availability, or other user-defined criteria and divides the logical-path mask into a preferred path subset and a non-preferred path subset. If a valid path exists in the preferred path subset, all communications from the host computer to the data storage device transit paths belonging to this subset. Otherwise, active control is given to the non-preferred path subset. A channel subsystem manages actual communication based on resource allocation and contention using the currently active subset.
