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.

One apparatus includes a storage division selection module configured to select a storage division of a solid-state storage medium for recovery. The solid-state storage medium includes a plurality of storage divisions. Each storage division includes a plurality of storage locations. The apparatus also includes an erase module configured to erase the selected storage division. The apparatus includes a storage division recovery module configured to store a sequence indicator in the erased storage division. The sequence indicator is indicative of an ordered sequence of the plurality of storage divisions, and the sequence indicator is determined by reading information stored with data on the plurality of storage divisions.

One method includes streaming a data segment to a write buffer corresponding to a virtual page including at least two physical pages. Each physical page is defined within a respective solid-state storage element. The method also includes programming contents of the write buffer to the virtual page, such that a first portion of the data segment is programmed to a first one of the physical pages, and a second portion of the data segment is programmed to a second one of the physical pages.

Systems and methods for storage parallelism

An apparatus, system, and method are disclosed for managing data in a solid-state storage device. A solid-state storage and solid-state controller are included. The solid-state storage controller includes a write data pipeline and a read data pipeline The write data pipeline includes a packetizer and an ECC generator. The packetizer receives a data segment and creates one or more data packets sized for the solid-state storage. The ECC generator generates one or more error-correcting codes ('ECC') for the data packets received from the packetizer. The read data pipeline includes an ECC correction module, a depacketizer, and an alignment module. The ECC correction module reads a data packet from solid-state storage, determines if a data error exists using corresponding ECC and corrects errors. The depacketizer checks and removes one or more packet headers. The alignment module removes unwanted data, and re-formats the data as data segments of an object.

An apparatus and system are disclosed for an in-server storage area network ('SAN'). A first storage controller is included within a first server. The first storage controller controls at least one storage device. The first server includes a network interface shared by the first server and the first storage controller. A storage communication module is included that facilitates communication between the first storage controller and at least one device external to the first server, where the communication between the first storage controller and the external device is independent from the first server. An in-server SAN module is included that services a storage request using at least one of a network protocol and a bus protocol. The in-server SAN module services the storage request independent from the first server, the service request received from a client.

An apparatus, system, and method are disclosed for storage space recovery in solid-state storage. A sequential storage module sequentially writes data packets in a storage division. The storage division includes a portion of a solid-state storage. The data packets are derived from an object. The data packets are sequentially stored by order of processing. A storage division selection module selects a storage division for recovery. A data recovery module reads valid data packets from the storage division selected for recovery, queues the valid data packets with other data packets to be written sequentially, and updates an index with a new physical address of the valid data. The index includes a mapping of physical addresses of data packets to object identifiers. A storage division recovery module marks the storage division selected for recovery as available for sequentially writing data packets in response to completing copying valid data from the storage division.

Apparatus, system, and method for storage space recovery in solid-state storage

An apparatus, system, and method are disclosed for storage space recovery after reaching a read count limit. A read module reads data in a storage division of solid-state storage. A read counter module then increments a read counter corresponding to the storage division. A read counter limit module determines if the read count exceeds a maximum read threshold, and if so, a storage division selection module selects the corresponding storage division for recovery. A data recovery module reads valid data packets from the selected storage division, stores the valid data packets in another storage division of the solid-state storage, and updates a logical index with a new physical address of the valid data.

An apparatus, system, and method are disclosed for a modular blade. The blade has a first carrier card and a second carrier card. At least one of these cards connects into the backplane of a blade server and provides connectivity for the modular blade to the backplane. The carrier cards also provide connectivity between their respective attached devices. In order to increase the density available in a modular blade, the computing components on the first and second cards interleave with one another such that a maximum number of components fit in a minimal space. The modular blade also provides an airflow channel for air circulation necessary to provide cooling. The first carrier card and second carrier card may also be identical, with one of the identical pair rotated one-hundred and eighty degrees with respect to the other.
