Abstract: A method and system for eliminating the redundant allocation and deallocation of special data on disk, wherein the redundant allocation and deallocation of special data on disk is eliminated by providing an innovate technique for specially allocating special data of a storage system. Specially allocated data is data that is pre-allocated on disk and stored in memory of the storage system. “Special data” may include any pre-decided data, one or more portions of data that exceed a pre-defined sharing threshold, and/or one or more portions of data that have been identified by a user as special. For example, in some embodiments, a zero-filled data block is specially allocated by a storage system. As another example, in some embodiments, a data block whose contents correspond to a particular type document header is specially allocated.

Abstract: A file system layout apportions an underlying physical volume into one or more virtual volumes of a storage system. The virtual volumes having a file system and one or more files organized as buffer trees, the buffer trees utilizing indirect blocks to point to the data blocks. The indirect block at the level above the data blocks are grouped into compression groups that point to a set of physical volume block number (pvbn) block pointers.
