Abstract: A data storage device includes: a data storage medium; a processor comprising a plurality of processor cores; a plurality of application acceleration black-box (AABB) slots including reconfigurable logic blocks, interconnects, and memories; a host interface that receives a host command from a remote application running on a remote host computer, wherein the host command includes an image file including a register-transfer level (RTL) bitstream and a firmware driver; and a configuration controller that downloads the RTL bitstream to an AABB slot of the plurality of AABB slots and reconfigure the AABB slot, and load the firmware driver to a processor core of the processor. The processor core loaded with the firmware driver runs a data acceleration process of the remote application to access and process data stored in the data storage medium using the RTL bitstream downloaded in the AABB slot.

Abstract: A system and method for providing erasure code data protection for an array of solid state drives. The solid state drives are connected to an Ethernet switch which includes a RAID control circuit, or a state machine, to process read or write commands that may be received from a remote host. The RAID control circuit, if present, uses a low-latency cache to execute write commands, and the state machine, if present, uses a local central processing unit, which in turn uses a memory as a low-latency cache, to similar effect.

Abstract: A system and method for distributed erasure coding. A plurality of storage devices is directly connected to one or more host computers, without an intervening central controller distributing data to the storage devices and providing data protection. Parity codes are stored in one or more dedicated storage devices or distributed over a plurality of the storage devices. When a storage device receives a write command, it calculates a partial parity code, and, if the parity code for the data being written is on another storage device, sends the partial parity code to the other storage device, which updates the parity code using the partial parity code.

Abstract: A method includes: receiving a Transmission Control Protocol (TCP)/Internet Protocol (IP) packet from an initiator, wherein the TCP/IP packet includes an IP address of a switch and a port number; looking up an address translation table based on the IP address of the switch and the port number; translating the IP address of the switch to a private IP address based on the port number according to address mapping information stored in the address translation table; and routing the TCP/IP packet to a non-volatile memory express over fabrics (NVMeoF) device having the private IP address. A network address translation (NAT) router implemented in the switch is configured to perform the address translation from the IP address of the switch to the private IP address of the NVMeoF device.
