  • Patent number: 8234250
    Abstract: A method and apparatus for deduplication of files of a storage system is described. During a gathering phase, a file may be simultaneously processed by two or more threads to produce and store content identifiers for data blocks of the file. Each file may be sub-divided into multiple file sub-portions, each file sub-portion comprising a predetermined number of data blocks. A thread may be assigned to each sub-portion of a file for processing the data blocks. The currently assigned sub-portion for each thread may be recorded and used upon a system crash to restart each scanner thread at the currently assigned sub-portion to minimize the data blocks that are re-processed. The size of a file sub-portion may be predetermined based on the organization of inode data structures representing the files (e.g., based on the maximum number of pointers that an indirect block in the inode data structure may contain).

  • Publication number: 20120158670
    Abstract: A storage server is coupled to a storage device that stores blocks of data, and generates a fingerprint for each data block stored on the storage device. The storage server creates a fingerprints datastore that is divided into a primary datastore and a secondary datastore. The primary datastore comprises a single entry for each unique fingerprint and the secondary datastore comprises an entry having an identical fingerprint as an entry in the primary datastore. The storage server merges entries in a changelog with the entries in the primary datastore to identify duplicate data blocks in the storage device and frees the identified duplicate data blocks in the storage device. The storage server stores the entries that correspond to the freed data blocks to a third datastore and overwrites the primary datastore with the entries from the merged data that correspond to the unique fingerprints to create an updated primary datastore.

  • Patent number: 8165571
    Abstract: Wireless networks and methods are disclosed that provide for anonymous call blocking in wireless networks. A wireless network of the invention includes an MSC system and an HLR system. When a calling party initiates a call to a called party, the MSC system receives the call and generates a call setup message for the call. The call is anonymous, so the call setup message does not include caller ID information for the calling party. The MSC system receiving the call transmits the call setup message to the HLR system. The HLR system determines if the call setup message includes caller ID information, and determines if the called party subscribes to anonymous call blocking. Responsive to determining that there is no caller ID information in the call setup message and that the called party subscribes to anonymous call blocking, the HLR system instructs the MSC system to block the call.
