Abstract: A system and a method to detect malicious software written to an Ethernet solid-state drive (eSSD). The system includes an Ethernet switch, at least one SSD, and a baseboard management controller (BMC). The Ethernet switch receives write data from a communication network in response to a write command. The at least one SSD receives the write data from the Ethernet switch and stores the received write data. The BMC receives from the at least one SSD the received write data. The BMC determines whether the received write data contains malicious software. The received write data may be contained in a plurality of Ethernet packets in which case the BMC stores the received write data in a scan buffer in an order that is based on an assembled order of the received write data.

Abstract: A Lightweight Bridge (LWB) is disclosed. The LWB may be a circuit. An endpoint of the LWB that may expose a plurality of Physical Functions (PFs) to a host. A root port of the LWB may connect to a device and determine the PFs and Virtual Functions (VFs) exposed by the device. An Application Layer-Endpoint (APP-EP) and an Application Layer-Root Port (APP-RP) may translate between the PFs exposed by the endpoint and the PFs/VFs exposed by the device. The APP-EP and the APP-RP may implement a mapping between the PFs exposed by the endpoint and the PFs/VFs exposed by the device.

Abstract: According to one general aspect, a device may include a host interface circuit configured to communicate with a host device via a data protocol that employs data messages. The device may include a storage element configured to store data in response to a data message. The host interface circuit may be configured to detect when a tunneling command is embedded within the data message; extract a tunneled message address information from the data message; retrieve, via the tunneled message address information, a tunneled message stored in a memory of the host device; and route the tunneled message to an on-board processor and/or data processing logic. The on-board processor and/or data processing logic may be configured to execute one or more instructions in response to the tunneled message.

Abstract: A method may include receiving, at a storage device, a command for a data transfer between the storage device and a host, determining a specified data rate for the data transfer, and performing the data transfer between the storage device and the host based on the command, wherein the storage device may control the data transfer based on the specified data rate. The data transfer may include a peak portion and an idle portion. The method may further include controlling, at the storage device, a peak portion and an idle portion of the data transfer based on the specified data rate. The method may further include controlling, at the storage device, the data transfer based on a peak burst size. The specified data rate may be received from the host and/or determined by the storage device by monitoring one or more parameters of a data transfer.

Abstract: A system and method for providing erasure code protection across multiple storage devices. A data switch in a storage system connects a plurality of storage devices to a remote host. Each storage device is also connected to a controller, e.g., a baseboard management controller. During normal operation, read and write commands from the remote host are sent to respective storage devices through the data switch. When a write command is executed, the storage device executing the command sends a copy of the data to the controller, which generates and stores erasure codes, e.g., on a storage device that is dedicated to the storage of erasure codes, and invisible to the remote host. When a device fails or is removed, the controller reconfigures the data switch to redirect all traffic addressed to the failed or absent storage device to the controller, and the controller responds to host commands in its stead.
