A method of operating a telemetry capture system within a data storage system comprising storage devices is provided. The method includes generating a telemetry packet, and providing the telemetry packet to one or more taps via a telemetry path independent of data and control paths within the storage devices. The method also includes capturing the telemetry packet in one or more of the taps, and generating real-time telemetry data based at least on the telemetry packet.

Telemetry capture system for storage systems

Methods and devices for coherent holographic data channel techniques. Coherent techniques for data detection generally include homodyne and heterodyne detection. Techniques for quadrature homodyne detection, resampling quadrature homodyne detection, n-rature homodyne detection, and spatial wavefront demodulation. Coherent detection techniques in turn enable coherent channel modulation techniques such as phase modulation (including binary phase shift keying, or BPSK; phase quadrature holographic multiplexing, or QPSK; and quadrature amplitude modulation, or QAM). Coherent detection may also enable or improve the performance of other channel techniques such as partial response maximum likelihood (PRML), the various classes of extended PRML, and of noise-predictive maximum likelihood (NPML) detection.

Methods and apparatus for coherent holographic data channels

The present invention provides systems and methods for logically organizing data for storage and recovery on a data storage medium using a multi-level format. The present invention also provides systems and methods for protecting data stored on data storage medium so that the data may be recovered without errors.
