Microchip Technology Assigned Two Patents

Computing parity information in RAID array
Microchip Technology Inc., Chandler, AZ, has been assigned a patent (12386705) developed by Pulickal Aravindakshan; Anoop, Karnataka, India, for “system and methods for computing parity information in a RAID array.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A redundant disk array may include redundant information to facilitate rebuilding the array in the event of a disk failure. A host processor may allocate buffers in an accelerator memory. Data may be moved from one or more storage devices to the buffers. An accelerator engine may perform parity calculations required to rebuild the array based on data in the buffers without requiring a host CPU to perform the parity calculation.”

The patent application was filed on 2023-10-10 (18/378414).

Parity calculation in storage arrays
Microchip Technology Inc., Chandler, AZ, has been assigned a patent (12386703) developed by Pulickal Aravindakshan; Anoop, and Bannuru; Raja Sekhar Reddy, Karnataka, India, for “system and methods for parity calculation in storage arrays.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system may include a storage array comprised of one or more array member drives. The storage array may be partitioned into stripes of data across the one or more array member drives. In operation, a DMA controller may move source data from a processor memory and may write the data to an accelerator memory. The accelerator may perform a parity calculation and a DMA controller may write the parity result and the source data to at least one of the array member drives. The parity information may be used to reconstruct data in the one or more array member drives in the case of damage or loss of data.”

The patent application was filed on 2024-04-17 (18/637549).
