The travel plan includes a set of intermediate data delivery destinations based on travel mode, travel route, travel schedule, and geographic locations of stops corresponding to the set of intermediate data delivery destinations. The data content is migrated to a set of data storage locations as the user travels based on the pattern of data access, the travel plan, and the set of intermediate data delivery destinations along the travel route. The data content is delivered to the user at geographic locations corresponding to the set of data storage locations as the user travels.

Abstract: A data storage system includes multiple tiers of data storage accessible by multiple hosts. The multiple tiers include an upper tier having a lower access latency and a lower tier having a higher access latency. For each extent among a plurality of extents of file system objects in the data storage, the storage controller separately tracks, for each of one or more hosts that access the extent, a respective heat indicative of a frequency of access by that host. In response to an event disassociating a first host among the multiple hosts from a particular extent among the plurality of extents, the storage controller recalculates an overall heat of the particular extent while excluding a first heat of the first host for the particular extent. The storage controller migrates extents among the multiple tiers based on overall heats of the plurality of extents.
