Mellanox/Nvidia Assigned Four Patents

Pluggable security devices and systems including same
Mellanox Technologies, Ltd., Yokneam, Israel, (acquired by Nvidia Corp.), has been assigned a patent (11729181) developed by Zimmerman, Shy, Kibutz Magal, Israel, Levy, Gil, Hod Hasharon, Israel, Haramaty, Zachy, Hemed, Israel, and Ger, Andrey, Shlomi, Israel, for “pluggable security devices and systems including the same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A networking system includes a pluggable security device comprising at least one port interface that is insertable into at least one physical port, memory that stores a security key used to provide security over a network link, and processing circuitry coupled with the at least one port interface and with the memory. The processing circuitry utilizes the security key to verify security of a point-to-point connection established over the network link and after verifying the security of the point-to-point connection, provides a data integrity check function for data packets received at the at least one port interface.”

The patent application was filed on 2020-11-16 (17/098986).

Network adapter with efficient storage-protocol emulation
Mellanox Technologies, Ltd., Yokneam, Israel, (acquired by Nvidia Corp.), has been assigned a patent (11726666) developed by Ben-Ishay, Ben, Tel Aviv, Israel, Pismenny, Boris, Zack, Yorai Itzhak, Haifa, Israel, Manaa, Khalid, Majd Alkrum, Israel, Liss, Liran, Misgav, Israel, Basher, Uria, Ganei Tal, Israel, Gerlitz, Or, Ramat-Gan, Israel, and Menes, Miriam, Tel Aviv, Israel, for “pluggable security devices and systems including the same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A network adapter includes a network interface controller and a processor. The network interface controller is to communicate over a peripheral bus with a host, and over a network with a remote storage device. The processor is to expose on the peripheral bus a peripheral-bus device that communicates with the host using a bus storage protocol, to receive first I/O transactions of the bus storage protocol from the host, via the exposed peripheral-bus device, and to complete the first I/O transactions in the remote storage device by (i) translating between the first I/O transactions and second I/O transactions of a network storage protocol, and (ii) executing the second I/O transactions in the remote storage device. For receiving and completing the first I/O transactions, the processor is to cause the network interface controller to transfer data directly between the remote storage device and a memory of the host using zero-copy.”

The patent application was filed on 2021-07-11 (17/372466).

Secure flash controller
Mellanox Technologies, Ltd., Yokneam, Israel, (acquired by Nvidia Corp.), has been assigned a patent (11681635) developed by Itkin, Yuval, Zoran, Israel, Strassberg, Yaniv, Yokneam, Israel, Harel, Guy, Haifa, Israel, and Atamlh, Ahmad, Oxford, Great Britain, for a “secure flash controller.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A computing device includes a non-volatile memory (NVM) interface and a processor. The NVM interface is configured to communicate with an NVM. The processor is configured to store in the NVM Type-Length-Value (TLV) records, each TLV record including one or more encrypted fields and one or more non-encrypted fields, the non-encrypted fields including at least respective validity indicators of the TLV records, to read the TLV records that include the encrypted fields and the non-encrypted fields from the NVM, and to invalidate selected TLV records by modifying the respective validity indicators of the selected TLV records that are stored in the non-encrypted fields.”

The patent application was filed on 2020-09-07 (17/013693).

DMA engine for diagnostic data
Mellanox Technologies, Ltd., Yokneam, Israel, (acquired by Nvidia Corp.), has been assigned a patent (11637739) developed by Aibester, Niv, Herzliya, Israel, Kfir, Aviv, Nili, Israel, Levy, Gil, Hod Hasharon, Israel, and Mula, Liron, Ramat Gan, Israel, for a “Direct Memory Access (DMA) engine for diagnostic data.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A network-connected device includes at least one communication port, packet processing circuitry and Diagnostics Direct Memory Access (DMA) Circuitry (DDC). The at least one communication port is configured to communicate packets over a network. The packet processing circuitry is configured to receive, buffer, process and transmit the packets. The DDC is configured to receive a definition of (i) one or more diagnostic events, and (ii) for each diagnostic event, a corresponding list of diagnostic data that is generated in the packet processing circuitry and that pertains to the diagnostic event, and, responsively to occurrence of a diagnostic event, to gather the corresponding list of diagnostic data from the packet processing circuitry.”

The patent application was filed on 2021-01-10 (17/145341).
