Abstract: A read channel and method using that read channel are disclosed. The read channel comprises an analog to digital converter which asynchronously samples at a fixed rate an analog signal formed by reading a data track, where that data track was written to a data storage medium at a symbol rate and an interpolator interconnected with the analog to digital converter. The read channel further comprises a fractionally-spaced equalizer, where the interpolator provides an interpolated signal to the fractionally-spaced equalizer at an interpolation rate, where that interpolation rate is greater than the symbol rate. The fractionally-spaced equalizer forms a synchronous equalized signal. The read channel further comprises a gain control module interconnected with the fractionally-spaced equalizer, and a sequence detector interconnected with the gain control module.

Abstract: A method to update code in an information storage and retrieval system comprising one or more processors, and existing code, where that existing code includes a Concurrent Code Load having (N) phases, where that Concurrent Code Load invokes an as yet unwritten Temporal Coupling File. The method provides a code update image comprising that Temporal Coupling File. If the (i)th phase of the Concurrent Code Load invokes the Temporal Coupling File, then the method reads instructions for that (i)th phase of the Concurrent Code Load from the Temporal Coupling File, and executes those instructions. The method completes each phase of the Concurrent Code Load, and then operates the system using the code update.

Abstract: A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.

Abstract: A method is disclosed to assign addresses to a plurality of data storage devices. The method provides a switch and (N) data storage devices, where each of those (N) data storage devices is interconnected with said switch. The method further establishes (M) device addresses, where (M) is less than (N), and assigns a different one of each of the (M) device addresses to a different one of the (N) data storage devices, such that the (N) data storage devices comprise (M) address-assigned data storage devices and (P) non-address-assigned data storage devices. The method then detects a failure of the (i)th address-assigned data storage device, and transfers the (i)th address from the failed address-assigned data storage device to the (j)th data storage device, where that (j)th data storage device comprises one of the (P) previously non-addressed data storage devices.

Abstract: A method to write information to a designated information storage medium using an allocated data storage device using a specified information recording format, whereby a previously-determined media bit for the designated information storage medium is examined, and a previously-determined device bit for the allocated data storage device is examined, and the write capability of the designated information storage medium using the specified information recording format is determined and displayed. Management classes embedded in the file name may augment the media bit and device bit for determining the write capability.

Abstract: A method to adjust the data transfer rate for one of (N) primary backup appliances. The method forms by a first primary backup appliance at least one consistent transactions set. The first primary backup appliance receives the (n)th status signal, and the (n+1)th status signal from each of the other (N?1) primary backup appliances. The method calculates the (n)th effective bandwidth for each of the (N) primary backup appliances, the (n)th time to complete for each of the (N) primary backup appliances, and the (n)th effective aggregate bandwidth for all (N) primary appliances. If the (n)th time to complete for the first primary backup appliance is greater than the (n)th time to complete for each of the other (N?1) primary backup appliances, then the method provides at least one consistent transactions set from the first primary backup appliance to a first secondary backup appliance with no delay.

Abstract: A method to generate a formatted trace for a second device embedded in a first device. The method provides source code comprising a trace entry, compiles that source code to form an embedded device code image comprising a trace description string and a trace description string address, and assigns the trace description string address as the traceId. The method creates a database comprising the trace description string and the trace description string address. The method uploads to the second device the embedded device code image, and generates trace data using that stripped code. The method then downloads that trace data to the first device, merges that trace data with the database, and forms a formatted trace.

Abstract: A method to update a data structure is disclosed. The method receives a write thread, and sets a data structure indicator to indicate that the data structure is unusable. The method creates (N) thread indicators, and assigns each of said (N) indicators to a different one of said (N) threads. Upon return to the thread dispatcher, the (i)th thread sees the data structure indicator which shows that the data structure is unusable. The method then sets the (i)th thread indicator to indicate that upon subsequent dispatches the (i)th thread will see the data structure indicator that shows that the data structure is unusable. After each of the (N) threads has seen the data structure indicator marking the data structure as unusable, the method sets the data structure indicator to indicate that the data structure is invalid, updates the data structure, and sets the data structure indicator to indicate that the data structure is valid.

Abstract: A system, method and article of manufacture are provided to perform an automated concurrent licensed internal code (LIC) update and an automated nonconcurrent LIC update on a storage controller. The automated concurrent LIC update is performed on a storage controller by sequentially updating each cluster while maintaining operation of the storage controller. The automated concurrent LIC update allows multiple hosts to continue to access data via the storage controller while the system is actively undergoing the LIC update. The automated nonconcurrent LIC update is performed during the time the storage controller in not operating. The automated nonconcurrent LIC update allows service personnel to perform the update in an efficient and timely manner. When the update has completed, the storage controller becomes available to process data and the system is operating at the latest LIC level.
