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 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.

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: Provided are systems, methods, and apparatuses for performing communication management. The method can include: receiving, via a first port, in-band data from a management device; generating routing information for routing the in-band data to at least one storage device in a chassis; applying the routing information to a header of a packet of data associated with the in-band data; and transmitting, via a second port, the in-band data to the storage device based on the routing information.

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.
