A method for managing data in a NAND flash storage system is provided. The method includes one or more of receiving an empty data segment directive at a storage controller, returning a data string including data of a predetermined logic level in response to a read command requesting to read data associated with a logical identifier included in the empty data segment directive, maintaining an index of mapping between the logical identifier and a physical storage location, updating the index to indicate data at the physical storage location does not need to be preserved, monitoring one or more physical storage locations, including the physical storage location, to determine a percentage of the one or more physical storage locations that do not need to be preserved, and initiating garbage collection on the one or more physical storage locations in response to the percentage reaching a threshold. The empty data segment directive includes a logical identifier associated with the physical storage location.

A system is provided. The system includes a solid state storage including a plurality of banks, a first controller that directs one or more commands to a queue of a set of a plurality of queues, and a second controller configured to receive the one or more commands from the plurality of queues. The one or more commands are separated into the set of the plurality of queues based on a command type of each command of the one or more commands, and each set of the plurality of queues includes a first queue configured to store management commands and a second queue configured to store other commands. Each bank of the plurality of banks corresponds to a different set of the plurality of queues. The second controller is configured to generate subcommands based on the commands and direct the subcommands to a bank of the solid state storage.

An apparatus, system, and method are disclosed for managing a non-volatile storage medium. A storage controller receives a message that identifies data that no longer needs to be retained on the non-volatile storage medium. The data may be identified using a logical identifier. The message may comprise a hint, directive, or other indication that the data has been erased and/or deleted. In response to the message, the storage controller records an indication that the contents of a physical storage location and/or physical address associated with the logical identifier do not need to be preserved on the non-volatile storage medium.

An apparatus, system, and method are disclosed for efficiently managing commands in a solid-state storage device that includes a solid-state storage arranged in two or more banks. Each bank is separately accessible and includes two or more solid-state storage elements accessed in parallel by a storage input/output bus. The solid-state storage includes solid-state, non-volatile memory. The solid-state storage device includes a bank interleave that directs one or more commands to two or more queues, where the one or more commands are separated by command type into the queues. Each bank includes a set of queues in the bank interleave controller. Each set of queues includes a queue for each command type. The bank interleave controller coordinates among the banks execution of the commands stored in the queues, where a command of a first type executes on one bank while a command of a second type executes on a second bank.

An electronic device with parallel backplanes and a storage device with parallel backplanes. The electronic device includes a front inserting assembly, a rear inserting assembly, and a backplane assembly. The backplane assembly is connected to the front inserting assembly and the rear inserting assembly. The backplane assembly includes a plurality of backplanes arranged in parallel at intervals, the front inserting assembly includes a plurality of first units whose arrangement direction is the same as an arrangement direction of the backplanes, and the rear inserting assembly includes a plurality of second units whose arrangement direction intersects the arrangement direction of the backplanes. The backplane assembly is provided with the structure including the plurality of backplanes arranged in parallel at intervals and the channel between adjacent backplanes. In addition, the first units and the second units are connected to two opposite sides of the backplanes, respectively.

A bracket for mounting a processor and a support structure for receiving bracket-supported processors for cluster computing are provided. In some embodiments, a bracket may be configured to receive a processor and fasten the processor to the bracket. The bracket may be configured to mount the processor to a support structure. The support structure may be configured to receive an array of brackets. The support structure may be configured to be stacked in combination with additional support structures.

An apparatus, system, and method are disclosed for efficiently managing commands in a solid-state storage device that includes a solid-state storage arranged in two or more banks. Each bank is separately accessible and includes two or more solid-state storage elements accessed in parallel by a storage input/output bus. The solid-state storage includes solid-state, non-volatile memory. The solid-state storage device includes a bank interleave that directs one or more commands to two or more queues, where the one or more commands are separated by command type into the queues. Each bank includes a set of queues in the bank interleave controller. Each set of queues includes a queue for each command type. The bank interleave controller coordinates among the banks execution of the commands stored in the queues, where a command of a first type executes on one bank while a command of a second type executes on a second bank.

Networking device serviceability may be provided. A networking device may be disposed in a rack between uprights. The networking device may comprise a first plurality of switch bars each comprising a first switch type arranged parallel to one another, a second plurality of switch bars each comprising a second switch type arranged parallel to one another, and a third plurality of switch bars each comprising a third switch type arranged parallel to one another. The first plurality of switch bars, the second plurality of switch bars, and the third plurality of switch bars may be arranged orthogonally. A hinge device associated with the networking device may be configured to allow the networking device to rotate at least a predetermined angle value from a first position between the uprights to a second position where both the first plurality of switch bars and the second plurality of switch bars are clear from the uprights.

A line card of a set of line cards is configured to be coupled to a set of switch-fabric cards to collectively define at least a portion of an orthogonal cross fabric without a midplane board. The line card has an edge portion, a first side and a second side, opposite the first side. The line card includes a set of first set of connectors and a second set of connectors. The first set of connectors is disposed along the edge portion on the first side of the line card and the second set of connectors is disposed along the edge portion on the second side of the line card.

A system is provided. The system includes a solid state storage including a plurality of banks, a first controller that directs one or more commands to a queue of a set of a plurality of queues, and a second controller configured to receive the one or more commands from the plurality of queues. The one or more commands are separated into the set of the plurality of queues based on a command type of each command of the one or more commands, and each set of the plurality of queues includes a first queue configured to store management commands and a second queue configured to store other commands.
