A user station for a serial bus system. The user station includes a receiver for receiving a signal from a bus of the bus system, and a device for evaluating the reception signal that is output by the receiver. The receiver generates a digital reception signal from the signal received from the bus and to output the signal to the device at a terminal. The device evaluates the digital reception signal with regard to a predetermined communication protocol that establishes when a predetermined communication phase, which indicates a subsequent transfer of useful data in a message, begins and ends. The device reverses the data flow of the digital reception signal to the receiver at the terminal for a time period of at least one bit if the evaluation of the device shows that data at that time are being received from the bus in the predetermined communication phase.

Aspects of the present disclosure are directed to performing varying frequency memory sub-system background scans using either or both a timer and an I/O event limit. This can be accomplished by identifying a background scan trigger event from one of multiple possible types of background scan trigger events, such as a timer expiration or reaching an event count limit. In response to the background scan trigger event, a background scan can be initiated on a memory portion. The background scan can produce results, such as CDF-based data. When a metric based on the results exceeds a background scan limit, a refresh relocation can be performed and logged. A metric can be generated based on the CDF-based data, obtained error recovery depth data, or refresh relocation event data. When the metric is above or below corresponding background scan thresholds, a background scan frequency can be adjusted.

A device connectable between a host computer and a computer peripheral over a standard bus interface is disclosed, used to improve security, and to detect and prevent malware operation. Messages passing between the host computer and the computer peripherals are intercepted and analyzed based on pre-configured criteria, and legitimate messages transparently pass through the device, while suspected messages are blocked. The device communicates with the host computer and the computer peripheral using proprietary or industry standard protocol or bus, which may be based on a point-to-point serial communication such as USB or SATA. The messages may be stored in the device for future analysis, and may be blocked based on current or past analysis of the messages. The device may serve as a VPN client and securely communicate with a VPN server using the host Internet connection.

A data storage device includes: a data storage medium; a processor comprising a plurality of processor cores; a plurality of application acceleration black-box (AABB) slots including reconfigurable logic blocks, interconnects, and memories; a host interface that receives a host command from a remote application running on a remote host computer, wherein the host command includes an image file including a register-transfer level (RTL) bitstream and a firmware driver; and a configuration controller that downloads the RTL bitstream to an AABB slot of the plurality of AABB slots and reconfigure the AABB slot, and load the firmware driver to a processor core of the processor. The processor core loaded with the firmware driver runs a data acceleration process of the remote application to access and process data stored in the data storage medium using the RTL bitstream downloaded in the AABB slot.

A host port is enabled for security. In response to a determination by the host port that authentication or security association negotiation with a storage port cannot be completed successfully, the host port determines whether an audit mode indicator has been enabled in a login response from the storage port. The host port preserves input/output (I/O) access to the storage port based on determining whether the audit mode indicator has been enabled in the login response from the storage port.

An apparatus includes at least one processing device, with the at least one processing device comprising a processor and a memory coupled to the processor. The at least one processing device is configured to generate a data copy offload command to offload a data copy operation from a host device to a storage system, the command comprising a multi-protocol indicator that specifies that data is to be copied from a source logical storage device that utilizes a first access protocol to a destination logical storage device that utilizes a second access protocol different than the first access protocol, and to send the data copy offload command from the host device to the storage system over a network for performance of the offloaded data copy operation in the storage system in accordance with the command. The first and second access protocols illustratively comprise respective SCSI and NVMe access protocols.

Techniques for transmitting data may comprise: receiving a first data transfer rate indicating a communication rate at which a first entity communicates with a second entity over a communications fabric; receiving a second data transfer rate indicating a communication rate at which the second entity communicates with the first entity over the communications fabric; and performing first processing to send first data from the first entity to the second entity over the communications fabric, said first processing including: determining whether the first data transfer rate is greater than the second data transfer rate; and responsive to determining the first data transfer rate is greater than the second transfer rate, performing second processing by the first entity that controls and limits, in accordance with the second data transfer rate, a rate at which the first data is transmitted from the first entity to the second entity.
