Abstract
A technique for managing block allocation in data storage systems involve providing multiple ranges of contiguous logical addresses (logical windows) in a logical address space of a file and allocating contiguous ranges of physical addresses (physical windows) in a file system to respective logical windows in response to requests to write data to logical addresses within the logical windows. When allocating blocks from one or more streams, each logical window to which writes are directed is mapped to a respective physical window, and each logical address in the logical window is mapped to a physical address in the physical window.
