Abstract: A rack-mountable data storage system includes: a chassis including one or more switchboards; a midplane interfacing with the one or more switchboards; and one or more data storage devices removably coupled to the midplane using a connector. At least one data storage device of the one or more data storage devices include a logic device to interface with the midplane. The logic device provides a device-specific interface of a corresponding data storage device with the midplane. The at least one data storage device is configured using the logic device according to a first protocol based on a signal on a pin of the connector, and the at least one data storage device is reconfigurable according to a second protocol based on a change of the signal on the pin of the connector using the logic device.

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 includes a fabric switch including a motherboard, a baseboard management controller (BMC), a network switch configured to transport network signals, and a PCIe switch configured to transport PCIe signals; a midplane; and a plurality of device ports. Each of the plurality of device ports is configured to connect a storage device to the motherboard of the fabric switch over the midplane and carry the network signals and the PCIe signals over the midplane. The storage device is configurable in multiple modes based a protocol established over a fabric connection between the system and the storage device.

Abstract: A rack-mounted system includes a chassis, a switchless board disposed in the chassis, a midplane, and a plurality of device ports. The switchless board includes a baseboard management controller (BMC), a network repeater configured to transport network signals, and a PCIe switch configured to transport PCIe signals. Each of the plurality of device ports is configured to connect a storage device to the midplane and carry the network signals and the PCIe signals over the midplane. The storage device is configurable to operate in one of multiple storage protocol modes based on a type of the chassis. The network repeater of the switchless board is swappable with an Ethernet switch to provide a switching compatibility to the chassis using the same midplane. The storage device can operate in single-port and dual-port configurations.

Abstract: A system includes a dynamic random-access memory (DRAM); and a storage device comprising a power source and a persistent store. The storage device is configured to provide reserve power to the DRAM. Data stored in the DRAM is transferred to a reserved storage in the persistent store of the storage device in a power loss event using the reserve power.

Abstract: A bridge device includes: a first interface configured to receive a first set of commands from an application running on a host computer; one or more command processors, each of the one or more command processors being configured to translate the first set of commands and generate a second set of commands based on the first set of commands; a second interface configured to provide the second set of commands to a data storage device; and a computing processor configured to issue an internal command to fetch data from the data storage device and write data to the data storage device in a background mode in an agnostic manner to the host computer while running the application.
