An apparatus, system, and method are disclosed for a baseboard management controller (BMC) which includes an FPGA with a monitor module for monitoring the operations parameters of a host computer device. In addition, the BMC has a host connector that connects the BMC to the system bus of the host computing device, allowing the BMC access to the computing elements on the host. The host connector has reconfigurable pins with connection configuration controlled by the FPGA. In addition, the BMC has a server with a processor and associated non-volatile memory on board. The operating system provides services to the host computing device and its constituent components, as well as allowing advanced networking and interconnectivity with other BMCs in a management network.

An apparatus, system, and method are disclosed for validating that correct data is read from a storage device. A hash generation module generates a hash value from a logical address of a read request for a data storage device. A read data module reads, from the data storage device, data identified by the read request and a stored hash value stored with the data. The stored hash value was generated from a logical address for data written to the data storage device. A hash check module verifies that the generated hash value matches the stored hash value read from the data storage device.

An apparatus, system, and method are disclosed for power loss management in a nonvolatile data storage device. A monitor module initiates a power loss mode in the nonvolatile data storage device in response to a primary power source failing to supply electric power above a predefined threshold to the nonvolatile data storage device. A secondary power source supplies electric power to the nonvolatile data storage device for at least a power hold-up time during the power loss mode. A power loss module adjusts execution of in-process operations on the nonvolatile data storage device during the power loss mode so that essential in-process operations execute within the power hold-up time.

An apparatus, system, and method are disclosed for improving performance in a non-volatile solid-state storage device. Non-volatile solid-state storage media includes a plurality of storage cells. The plurality of storage cells is configured such that storage cells in an empty state store initial binary values that satisfy a bias. An input module receives source data for storage in the plurality of storage cells of the non-volatile solid-state storage media. Bits of the source data have a source bias that is different from the bias of the plurality of storage cells. A bit biasing module biases the bits of the source data toward the bias of the plurality of storage cells. A write module writes the biased source data to the plurality of storage cells of the non-volatile solid-state storage media.

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.

An apparatus, system, and method are disclosed for detecting and replacing failed data storage. A read module reads data from an array of memory devices. The array includes two or more memory devices and one or more extra memory devices storing parity information from the memory devices. An ECC module determines, using an error correcting code (“ECC”), if one or more errors exist in tested data and if the errors are correctable using the ECC. The tested data includes data read by the read module. An isolation module selects a memory device in response to the ECC module determining that errors exists in the data read by the read module and that the errors are uncorrectable using the ECC. The isolation module also replaces data read from the selected memory device with replacement data and available data wherein the tested data includes the available data combined with the replacement data.

An apparatus, system, and method are disclosed for ensuring data validity in a data storage process. A data receiver module receives a storage block and existing parity information. An ECC generation module generates error correcting code (“ECC”) check bits for the data of the storage block in response to receiving the storage block and the existing parity information. The ECC check bits for the storage block are generated using a block code, a convolutional code, etc. A pre-storage consistency module uses the data of the storage block, the existing parity information, and the ECC check bits to determine if the data of the storage block, the existing parity information, and the ECC check bits are consistent. A data storage module stores the data of the storage block and the ECC check bits the data storage device without storing the existing parity information.

An apparatus, system, and method are disclosed to increase data integrity in a redundant storage system. The receive module receives a read request to read data from a logical page spanning an array of N+P number of storage elements. The array of storage elements includes N number of the storage elements each storing a portion of an ECC chunk and P number of the storage elements storing parity data. The data read module reads data from at least a portion of a physical page on each of X number of storage elements of the N+P number of storage elements where X equals N. The regeneration module regenerates missing data. The ECC module determines if the read data and any regenerated missing data includes an error. The read data combined with any regenerated missing data includes the ECC chunk.

An apparatus, system, and method are disclosed for validating that correct data is read from a storage device. A read request receiver module receives a read storage request to read a data segment of a file or object stored on a data storage device. The storage request includes one or more source parameters for the data segment. The source parameters include one or more virtual addresses that identify the data segment. A hash generation module generates one or more hash values from the virtual addresses. A read data module reads the requested data segment and returns one or more data packets and corresponding stored hash values stored with the data packets. The stored hash values were generated from a data segment written to the data storage device that contains data of the data packets. A hash check module verifies that the generated hash values match the respective stored hash values.
