Abstract: A mechanism is provided in a data processing system for on-demand caching in a wide area network (WAN) separated distributed file system or clustered file system. The mechanism monitors file access by a plurality of cache sites in the WAN separated distributed file system or clustered file system. The mechanism identifies access patterns by cache sites. The mechanism shares the access patterns with the plurality of cache sites. A given cache site within the plurality of cache sites combines the access patterns with local access information and identifies files to pre-fetch based on the combined information.

Abstract: A method and associated systems for efficient management of cloned data. One or more processors create a “child” clone of a “parent” software image. The child and parent contain identical information organized into identical sets of file blocks. To conserve storage, each child block initially points to a physical storage location already in use by a corresponding parent block, rather than requiring additional storage of its own. The first time a child block is updated, however, it will require additional physical storage. At the time of the child's creation, the processors reserve a number of physical blocks sufficient to store the contents of all child file blocks likely to be updated. A child file block is identified as likely to be updated by analyzing past volatility of a corresponding file block of the parent or of corresponding file blocks of other children of the same parent.

In response, the first set of memory blocks are transferred from the SSD memory device to a first portion of the hybrid storage device.
