Marvell Assigned Two Patents

File server for RAID system
Marvell World Trade, Saint Michael, Barbados, has been assigned a patent (8,495,416) developed by Pantas Sutardja, Los Gatos, CA, for a “file server for redundant array of independent disks (RAID) system.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system comprising an interface, a plurality of storage arrays, a data processing module, and a switch module. The interface receives data blocks from a host via a network. The data processing module connected between the interface and the plurality of storage arrays, wherein the data processing module is configured to (i) determine which ones of the data blocks each of a plurality of target processing modules of the storage arrays is to perform error checking and correcting processing, and (ii) transfer each of the data blocks from the interface to a respectively assigned one of the plurality of target processing modules. The switch module provides communication paths between the data processing module and the plurality of storage arrays.”

The patent application was filed on Oct. 24, 2011 (13/279,971).

Inter-track interference cancellation
in magnetic recording channels
Marvell International, Hamilton, Bermuda, has been assigned a patent (8,537,482) developed by four co-inventors for “systems and methods for inter-track interference cancellation in magnetic recording channels.”

The co-inventors are Hongxin Song, Sunnyvale, CA, Nitin Nangare, Santa Clara, CA, Michael Madden, Mountain View, CA, and Gregory Burd, San Jose, CA

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A receiver for a HDD drive system includes an analog front end module configured to sample a read-back signal and to output a digital read-back signal. An equalizer module is configured to generate a data vector based on the digital read-back signal. A detector module is configured to generate a decision vector based on the data vector. A re-timing module is configured to generate a first revised data vector based on the data vector and the decision vector. The re-timing module re-samples a plurality of samples in the data vector in a non-sequential time order to generate the first revised data vector. An inter-track interference (ITI) cancellation module is configured to remove ITI from the first revised data vector and to generate a second revised data vector.”

The patent application was filed on Feb. 3, 2012 (13/365,696).
