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 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 interface enables communication with the processor; a downstream interface enables 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 an endpoint 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.

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.
