    Abstract: A data storage system includes: a plurality of Ethernet solid-state drive (SSD) chassis including at least one switching Ethernet SSD chassis and one or more switchless Ethernet SSD chassis. The at least one switching Ethernet SSD chassis comprises an Ethernet switch, a first baseboard management controller (BMC), and a first management local area network (LAN) port. At least one of the one or more switchless Ethernet SSD chassis comprises an Ethernet repeater, a second BMC, and a second management LAN port. The first management LAN port of the at least one switching Ethernet SSD chassis and the second management LAN port are connected. The first BMC collects status of the at least one of the one or more switches Ethernet SSD chassis from the second BMC via a connection between the first management LAN port and the second management LAN port and provide device information of the at least one of the one or more switches Ethernet SSD chassis and the at least one switching Ethernet SSD chassis to a system administrator.

    Abstract: A method may include transferring data between a host and a first storage device through a first storage interface, transferring data between the host and a second storage device through a second storage interface, and transferring data between the first storage device and the second storage device through a peer-to-peer channel. A storage system may include a host interface, a first storage device having a first storage interface coupled to the host interface, a second storage device having a second storage interface coupled to the host interface, and a peer-to-peer bus coupled between the first and second storage devices. A storage device may include a storage medium, a storage device controller coupled to the storage medium, a storage interface coupled to the storage device controller, and a peer-to-peer interface coupled to the storage device controller.

    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 Peripheral Component Interconnect Express (PCIe) switch with Erasure Coding logic is disclosed. The PCIe switch may include an external connector to enable the PCIe switch to communicate with a processor and at least one connector to enable the PCIe switch to communicate with at least one storage device. The PCIe switch may include a Power Processing Unit (PPU) to handle configuration of the PCIe switch. The Erasure Coding logic may include an Erasure Coding Controller with circuitry to apply an Erasure Coding scheme to data stored on the storage device, and a snooping logic including circuitry to intercept a data transmission received at the PCIe switch and modify the data transmission responsive to the Erasure Coding scheme.

    Abstract: A system is disclosed. The system may include a processor running an application program and a memory storing data being used by the application program. An upstream endpoint enables communication with the processor; two downstream root ports enable communication with a storage device. The system may also include an acceleration module implemented using hardware and including an Acceleration Platform Manager (APM-F) to execute an acceleration instruction. The storage device may include two endpoints of the storage device for communicating with the acceleration module, a controller to manage operations of the storage device, storage for application data for the application program, and a storage device Acceleration Platform Manager (APM-S) to assist the APM-F in executing the acceleration instruction. The processor, the acceleration module, and the storage device may communicate via a Peripheral Component Interconnect Exchange (PCIe) bus. The acceleration module may support performing the acceleration instruction on the application data on the storage device for the application program without loading the application data into the memory.

    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.
