    Abstract: A controller of a data storage device includes: a host interface providing an interface to a host computer; a flash translation layer (FTL) translating a logical block address (LBA) to a physical block address (PBA) associated with an input/output (I/O) request; a flash interface providing an interface to flash media to access data stored on the flash media; and one or more deep neural network (DNN) modules for predicting an I/O access pattern of the host computer. The one or more DNN modules provide one or more prediction outputs to the FTL that are associated with one or more past I/O requests and a current I/O request received from the host computer, and the one or more prediction outputs include at least one predicted I/O request following the current I/O request. The FTL prefetches data stored in the flash media that is associated with the at least one predicted I/O request.

    Abstract: A storage system comprises one or more storage devices, power supplies supplying power to the storage device, a processor that performs in response to determining that the total power consumption of the one or more storage devices is less than a first percentage threshold of a load of the active power supplies, deactivating one or more of the active power supplies until the total power consumption is equal to or greater than the first percentage threshold of a load of each of the active power supplies, and in response to determining that the total power consumption is equal to or greater than a second percentage threshold of a load of each of the active power supplies, activating one or more of the deactivated ones of the power supplies until the total power consumption is less than the second percentage threshold of the load of each of the active power supplies.

    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 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.
