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 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: A system is disclosed that provides emergency backup power to a solid-state drive (SSD) that may not contain any internal supercapacitors. The SSD may include a first connector and a hold-up power supply. The first connector may have a predetermined form factor and may being capable of being connected to a corresponding connector of a midplane of a storage system. The first connector may include a main power connection that is connected to a main power supply of the midplane if the first connector is connected to the corresponding connector of the midplane. The hold-up power supply may be internal to the SSD, and may receive hold-up energy from an external energy source for a predetermined amount of time after the first connector has been disconnected from the main power connection of the midplane so that the SSD may store any host data write requests that the SSD has acknowledged.

Abstract: A device includes a communications circuit configured to communicate with a storage device controller and a host device. The device further includes a processing device configured to receive a request from the storage device controller through the communications circuit. The request requests encrypted data be written to a memory address of the host device. The processing device is further configured to identify a key associated with the write request based on the memory address. The processing device is further configured to generate a decrypted version of the data based on the key. The processing device is further configured to initiate transfer, through the communications circuit, of the decrypted version of the data to the host device.

Abstract: A system and method for differentiated storage services with a Ethernet SSD includes receiving, at an Ethernet SSD (eSSD), an input/output (I/O) service request from a remote host via a multiprotocol label switching (MPLS) network. The I/O service request includes at least one parameter that may be used to match the I/O service request to a label switched path (LSP) based on the parameter(s). A storage traffic stream may then be opened between the eSSD and the remote host over the MPLS network according to the LSP.

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.
