Abstract: A computing device includes a non-volatile memory (NVM) interface and a processor. The NVM interface is to communicate with an NVM. The processor is to store in the NVM at least a Type-Length-Value (TLV) record including one or more encrypted fields and one or more non-encrypted fields, the non-encrypted fields including at least a validity indicator of the TLV record, to read the TLV record from the NVM, and to invalidate the TLV record by modifying the validity indicator stored in the non-encrypted fields, without decryption of any of the encrypted fields.

Abstract: 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.

Abstract: An electro-optical (EO) interconnect assembly includes an optical fiber, and first and second EO transceivers. The first and second EO transceivers, which are coupled to respective ends of the optical fiber, are configured to (i) connect to respective first and second network devices, (ii) exchange electrical signals with the first and second network devices, (iii) convert between the electrical signals and optical signals, and exchange the optical signals with one another over the optical fiber, and (iv) conduct with one another, over the optical fiber, a secure challenge-response transaction, and to initiate a responsive action upon failure of the challenge-response transaction.

Abstract: A network adapter includes one or more network ports, multiple bus interfaces, and a processor. The one or more network ports are configured to communicate with a communication network. The multiple bus interfaces are configured to communicate with multiple respective Central Processing Units (CPUs) that belong to a multi-CPU device. The processor is configured to support an Option-ROM functionality, in which the network adapter holds Option-ROM program instructions that are loadable and executable by the multi-CPU device during a boot process, and, in response to a request from the multi-CPU device to report the support of the Option-ROM functionality, to report the support of the Option-ROM functionality over only a single bus interface, selected from among the multiple bus interfaces connecting the network adapter to the multi-CPU device.

Abstract: A network adapter includes one or more ports and circuitry. The ports are configured to connect to a switch in a communication network. The circuitry is coupled to a network node that includes multiple hosts, and is configured to exchange management packets between a control server and multiple BMC units associated respectively with the multiple hosts, and to exchange, over the communication network via the one or more ports, data packets between the hosts and one or more remote nodes.
