Abstract: An example system comprises one or more processing nodes to execute one or more processes; a switching fabric coupled to the one or more processing nodes; a fabric-attached memory (FAM) coupled with the switching fabric; and a memory allocator to allocate and release memory in the FAM in response to memory allocation requests and memory release requests from the one or more processes. The memory allocator is to partition the FAM into a memory shelf comprising a plurality of memory books of equal size. The memory allocator is to map a shelf into a virtual memory zone, the zone aligned with the boundaries of one or more books. The memory allocator is to maintain an indexed free-memory list where each index level is an entry point to a list of free memory blocks of a particular size in the zone, and the memory allocator to maintain a bitmap of the zone to identify if a memory block of a particular size is allocated.

Abstract: A network storage server implements a method to perform fast crawling of a hierarchical storage structure. The hierarchical storage structure contains data entities stored by a network storage server. The hierarchical storage structure can be recursively divided into a plurality of sections. A plurality of parallel-processing threads can be used to process the plurality of sections. Each thread selects and processes one of the plurality of sections at a time to generate a sorted list of metadata corresponding to the section of the hierarchical storage structure. The sorted lists generated by the plurality of threads are merged to a baseline list. The baseline list contains sorted metadata for entities managed by the hierarchical storage structure. The baseline list can then be outputted as a representation of the state of data stored by the network storage server.
