Latest Patents
One of his latest patents is titled "Multiple-channel failure detection in RAID systems." This invention presents a software-based method for facilitating the recovery of a RAID storage system from the simultaneous failure of two or more disks, which is considered a catastrophic failure. The method involves identifying the logical address and length of the failed areas on the disks and writing this information into a bad region table that is replicated on each disk. This innovation simplifies the identification of problem areas, making repairs easier and more cost-effective.
Another significant patent by Renner is "Firmware recovery from hanging channels by buffer analysis." This invention provides a software-based method for determining the identity of a failed (hanging) channel in an array of multiple, buffered, synchronized data channels. A hanging channel may arise from a failed storage unit, a faulty connection, or an issue in the interface circuitry. Identifying a hanging channel is crucial for isolation or repair. The detection method involves examining the byte content of the buffers, where discrepancies in byte counts indicate a hanging channel.
