Abstract: Described herein are a method, apparatus and computer readable medium for correcting data points acquired during well drilling. The data points are typically stored in a text file that is accessible by a processor. The processor applies one or more tags to the data points, with each of the tags corresponding to a characteristic of the data points. The processor then identifies one or more data faults in the data points using the one or more tags. Each data fault is indicative of inaccurate data in the data points; i.e., data that does not accurately represent the well as drilled. Following identification of the one or more data faults, the processor corrects one or more of the data faults. The resulting corrected, or cleaned, data is more indicative of the well as actually drilled than the uncorrected data. The processor can be connected to a computer readable medium that stores the statements and instructions that the processor executes.

Abstract: To produce a memory which resists ion or photon attack, a memory structure is chosen whose memory point behaves asymmetrically with regard to these attacks. It is shown that in this case, it is sufficient to have a reference cell for an identical and periodic storage structure in order to be able to correct all the memory cells assailed by an attack. An error correction efficiency of ½ is thus obtained, with a simple redundancy, whereas the conventional methods make provision, for the same result, to triple the storage, to obtain a less beneficial efficiency of ?.

Abstract: A data management system or “DMS” provides an automated, continuous, real-time, substantially no downtime data protection service to one or more data sources associated with a set of application host servers. To facilitate the data protection service, a host driver embedded in an application server captures real-time data transactions, preferably in the form of an event journal that is provided to other DMS components. The driver functions to translate traditional file/database/block I/O and the like into a continuous, application-aware, output data stream. The host driver includes an event processor. When an authorized user determines that a primary copy of the data in the host server has become incorrect or corrupted, the event processor can perform a recovery operation to an entire data source or a subset of the data source using former point-in-time data in the DMS. The recovery operation may have two phases.

In short, progress in error correction has potential to impact several storage and communication systems.

In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.

Abstract: A method, system and computer-usable medium are disclosed for managing storage system resources in a storage area network (SAN). A target data storage server registers itself within a storage area network (SAN) fabric to receive a Registered State Change Notification (RSCN) should a SCSI initiator become inactive. A SCSI initiator then requests reservation of a target LUN. In response, the target data server reserves the LUN for use by the SCSI initiator. If a RSCN is received by the target data storage server, then a GID_PN server request, which comprises the unique identifier of SCSI initiator, is generated after a predetermined time interval and a SAN fabric name server. If the name server's response to the GID_PN server request is positive, then the SCSI initiator was detected as being active and the target data storage server keeps the reservation for the LUN active for the SCSI initiator. Otherwise, the reservation for the LUN is released for use by other SCSI initiators.

The system stores information associated with driver(s) running on a specific device and allows a user to selectively revert to any one of a plurality of previously installed device driver(s), for example, if they experience a problem with a newer driver. Rollback point(s) can be stored, for example, in the system registry.

Abstract: A receiver circuit is described. In the receiver circuit, an analog-to-digital converter (ADC) generates first samples of a data signal based on a first clock signal, and a clock-data-recovery (CDR) error-detection circuit generates second samples of the data signal based on a second clock signal. In addition, the CDR error-detection circuit estimates intersymbol interference (ISI) at a current sample in the second samples from an adjacent, subsequent sample in the second samples. Based on the second samples and the estimated ISI, a CDR circuit generates the first clock signal and the second clock signal, which involves modifying the skews of either or both of these clock signals so that the current sample is associated with a zero crossing of a pulse response of a communication channel from which the data signal was received, thereby reducing or eliminating the ISI from the adjacent, subsequent sample.

Abstract: Apparatus, method and program product for relocating Bad Block Relocation Directory (BBRD) on a disk storage pre-allocate a number of areas for BBRD in different locations of the disk storage. The locations for the BBRD are calculated based upon the size of the disk and BBRD count. If the update of BBRD fails due to defective media at the location to be updated, that location is abandon and the next pre-allocated location is used. A copy of the BBRD is stored in RAM and maintained by the kernel. By so doing, when a bad block in the BBRD is detected the kernel causes the BBRD to be written in a good one of the locations reserved for BBRD. When the number of alternate BBRD locations used hits a pre-defined threshold, this indicates a situation where many sections of the disk are going bad and the disk needs replacement. If all BBRD locations are used, the disk is presumed bad and all future I/O activities to the disk is suspended.
