A multi-function device is disclosed. A first port may be used to communicate with a host processor. A second port may be used to communicate with a storage device. A third port may be used to communicate with a computational storage unit. Circuit may be used to route a message from the host processor to at least one of the storage device or the computational storage unit.

A data transmission method, apparatus, and device and a storage medium. A control instruction sent by a first node main program is received and analyzed; when the control instruction is analyzed to be a first control instruction for controlling a first node, a value is assigned to a first variable of the first node; the first control instruction is executed to obtain first result data and fed back same to the first node main program; the first variable of the first node is sent to a second node SES program, so that the second node SES program receives and analyzes same, and assigns a value to a second variable of a second node. According to the method, in a multi-controller data processing situation, node data transmission is increased, redundant link control of a two-node SES program by one node is implemented, and an information interaction redundancy mechanism can be enhanced.

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.

An electronics assembly including a plurality of midplanes positioned between and coupled to a plurality of electronic components at one side of the plurality of midplanes and at least one electronic component at an opposite side of the plurality of midplanes in a manner so that the midplanes are vertically oriented in parallel relative to each other so as to define spaces therebetween. The midplanes each include electrical traces configured to send signals among and between the plurality of electronic components at the one side of the midplanes and the at least one electronic component at the opposite side of the midplanes.

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 method of identifying an unsupported storage device on a server is disclosed as including providing the server with a baseboard management controller (BMC), the BMC obtaining vital product data (VPD) from a storage device on the server, the BMC comparing the VPD from the storage device with one or more approved VPDs, and the BMC issuing an output in response to said comparison.

The disclosed technology includes a storage system with a docking station configured to serve as an interface between a host computer and a portable data pack including multiple storage drives. The docking station includes a drive-side connection interface that provides a physical and electrical coupling to each of the multiple storage drives in the portable data pack, a RAID controller, and mode selection logic for directing communications in route between the host computer and a select drive of the multiple storage drives along one of two selectable paths within the docking station, the first path permitting the host computer to interact with the select drive through the RAID controller and the second path permitting the host computer to interact with the select drive along a data channel that bypasses the RAID controller.

A system includes a fabric switch including a motherboard, a baseboard management controller (BMC), a network switch configured to transport network signals, and a PCIe switch configured to transport PCIe signals; a midplane; and a plurality of device ports. Each of the plurality of device ports is configured to connect a storage device to the motherboard of the fabric switch over the midplane and carry the network signals and the PCIe signals over the midplane. The storage device is configurable in multiple modes based a protocol established over a fabric connection between the system and the storage device.

An electronic device configured to communicate with a host includes: a detecting logic configured to receive an initial command signal and a first completion signal according to the initial command signal after a connection of the host to the electronic device is established, and transmit a detection signal based on a signal transmission policy of the host that has been detected based on the initial command signal and the first completion signal; and a transmitting logic configured to transmit a second completion signal to the host based on the detection signal, wherein the signal transmission policy is different depending on whether the first completion signal is received in response to the second completion signal.

According to one embodiment, a memory system includes a nonvolatile memory and a memory controller configured to execute a patrol process, in response to a first command set from a host device. In the patrol process, the memory controller is configured to read first data from the nonvolatile memory, and not to output the first data to the host device.
