Abstract: A system and method for “on-the-fly” de-duplication of data before storing the data in a storage system. A data de-duplication module illustratively cooperates with protocol servers and a file system of a storage operating system executing on the storage system to implement the novel de-duplication technique. The de-duplication module illustratively generates a block store, an index file and a hash table on storage space provided by the storage system. The hash table is utilized for tracking fingerprints and locations of blocks within the block store. The index file is utilized for storing directory information identifying the contents of data containers stored on the storage system, while the block store is utilized to store raw data blocks that comprise the data containers.

Abstract: A system and method encapsulates selected functionality of a programming environment, defines an interface to the encapsulated functionality, and utilizes the encapsulated functionality from within an add-on toolbox to the programming environment through the interface. Objects may be constructed from the selected functionality of the programming environment. The functionality may be built-in or custom designed functionality. The objects are registered with the add-on test toolbox, and made available to a user of the add-on toolbox. The user may enter information into a user interface specifying selected functionality and its properties. An object manipulation engine receives the to information entered into the user interface, and uses it to issue calls through the interface to construct the objects and invoke one or more of the methods.

A user status of a particular application may be determined, and in response to that user status for the particular application, the feature set of at least one other application may be dynamically adjusted.

Abstract: A system and method for verifying the consistency of mirrored data sets between source and destination storage systems is provided. A destination verification module sends version information to the source storage system where the source verification module determines whether the source and destination storage systems are utilizing compatible versions of the verification module. If the destination verification module receives an acceptable version from the source, the destination module then determines a base PCPI to utilize for verification and sends a PCPI identifier of the base PCPI to the source. The source verification module generates and transmits a data stream consisting of comprising of checksum information. The destination verification module compares the received data stream with checksum information retrieved from disk. If there are mismatches, i.e. the received data differs from the data retrieved from disk, the destination verification module logs the data mismatches in a verification log file.

Abstract: Described is a process for encrypting and compressing data for storage by computing systems. A data stream received by a computing system is separated into data chunks for storage on a storage device using a data layout format. Each data chunk is examined and if possible, compressed to produce a compressed data chunk. Whether or not the data chunk can be compressed, the data chunk is encrypted and stored on the storage device in addition to metadata that describes the data chunk. When reading the stored data chunk from the storage device, the metadata identifies the starting location of the stored data chunk and provides metadata information to the computing system for decryption and decompression processing.

Abstract: A method and system of aligning a probe to wells includes holding the probe at one potential and holding the wells at a different potential, moving the probe to an estimated center position above a selected well, lowering the probe into the selected target well, moving the probe in positive and negative directions along first and second axial dimensions until changes in potential are detected at the probe to indicate electrical contact between the probe and the selected well, and calculating a center location of the selected well along the first and second axial dimensions as mid-points between the points of contact for the respective axial dimensions. The method and system further include lowering the probe into contact with a floor of the selected well and calculating a center location along a third axial dimension as a predetermined distance above the position of the probe.

Abstract: A system and method for performing a distributed consistency check of a clustered file system. File system functions for loading an inode and/or buffer tree are modified so that in response to either of these functions being invoked, a consistency check is performed. The consistency check verifies both local consistency on a node of the clustered file and a distributed check across the nodes of the storage system.

The appearance of the particular virtual room may be updated to reflect the changed state.

Abstract: A system and method for managing data deduplication of a storage system utilizing persistent consistency point images (PCPIs). Once a target PCPI of a data transfer is generated, a backup management module of the storage system alerts a data deduplication module to begin deduplication of the data contained within the target PCPI. Once the deduplication procedure has been completed, the active file system of the storage system has been deduplicated, however, the target PCPI remains un-deduplicated. In response, the backup management module generates and exports a revised target PCPI. The previous target PCPI may then be deleted, thereby transitioning the exported PCPI's image of the state of the file system to a deduplicated state.

Abstract: In one embodiment, a more capable device (MCD) in a computer network may determine one or more a critical destinations (CDs), and may transmit an unsolicited reactive routing route request (RREQ) message to each CD. The MCD may then receive a route reply (RREP) message from the CDs having a route from the MCD to the CD, and may store the route at the MCD. Subsequently, the MCD may transmit a RREP message of its own to one or more less capable devices (LCDs) to provide the route from each respective LCD to the CD via the MCD.

Abstract: A group stamping style asynchronous replication service utilizes a loosely-accurate global clock in a data backup and recovery storage environment. The storage environment includes a set of source storage systems illustratively embodied as source replication nodes that cooperate to maintain a consistency group that may span multiple geographical sites. The storage environment also includes one or more target storage systems illustratively embodied as target replication nodes configured to service the consistency group. The group stamping style service utilizes the loosely-accurate global clock to provide consistent replication of a storage space, e.g., a target storage space, of the consistency group.

Abstract: Temperature compensation for ion-selective electrodes is obtained by positioning a temperature-measuring element in a chamber of limited thermal mass which is in thermal contact with the measuring electrode filling solution but is thermally isolated from other filling solutions in the electrode. In a preferred embodiment, the temperature-measuring element comprises a thermistor enclosed within thin flexible tubing; the electrical leads of the thermistor are forced against a segment of the inner wall of the tubing by an elongated strand of material abutting the thermistor to enhance heat transfer with the thermistor.

Abstract: A system and method for transparently compressing file system data using compression group descriptors is provided. When data contained within a compression group be compressed beyond a predefined threshold value, a compression group descriptor is included in the compression group that signifies that the data for the group of level 0 blocks is compressed into a lesser number of physical data blocks. When performing a read operation, the file system first determines the appropriate compression group that contains the desired data and determines whether the compression group has been compressed. If so, the file system decompresses the data in the compression group before returning the decompressed data. If the magic value is not the first pointer position, then the data within the compression group was previously stored in an uncompressed format, and the data may be returned without performing a decompression operation.

Abstract: A system and method for management of jobs in the clustered environment is provided. Each node in the cluster executes a job manager that interfaces with a replicated database to enable cluster wide management of jobs within the cluster. Jobs are queued in the replicated database and retrieved by a job manager for execution. Each job manager ensures that jobs are processed through completion or, failing that, are re-queued on another storage system for execution.
