A storage system includes at least one solid-state drive (SSD) and a baseboard management controller (BMC). The at least one SSD communicates over a communication link information that the at least one SSD includes a predetermined number of super capacitors in which the predetermined number includes 0, and is capable of providing a mode of operation to flush data in a non-volatile memory to a non-volatile memory that spans a predetermined amount of time if a loss of power condition is detected. The BMC device receives the information from the SSD and in response sends a message to the at least on SSD to enter the mode of operation.

Cost-effective solid state disk data-protection method for power outages

A computer-implemented method can include: a computer program file open request providing read access to text or binary plaintext file data residing on a data storage means; processing the plaintext file data in an input data buffer area following a computer program file data read operation to improve performance by creating a multiplicity of processing threads to perform concurrent, usually non-overlapping encryption processing operations; and an encryption program constructing a previously constructed complex of Pseudo Random Number Generator (PRNG) means to provide on-demand Pseudo Random Number (PRN) values.

Aligned high performance data encryption method

A computer-implemented method can include encrypting a data file as a multiplicity of independent segments that are each a multiple of a block encryption's block size, encrypting the application data on a segment-by-segment basis using the multiplicity of selected encryption methods and associated information, and creating a programming shared object 'shim' Interposer module.

Dynamically encrypting and decrypting application data using dynamically linked interposer modules

A storage system is described. The storage system may include a plurality of storage tiers, each including at least one storage device, each storage device including storage and a controller. Metadata storage may store metadata for an image stored in the plurality of storage tiers, which includes a location in the plurality of storage tiers where the image is stored. A receiver may receive a request to access the image from a host. Retrieval software, executed by a processor, may retrieve the image from the plurality of storage tiers using the location where the image is stored. A transmitter may transmit the image to the host.

Method for accelerating image storing and retrieving differential latency storage devices based on access rates

A system can include: a plurality of processing Cores; a Package Interconnect communicatively coupled with the plurality of processing Cores; a Configurable LFSR PRV Generator Hardware Array means communicatively coupled with the Package Interconnect; a Galois Multiplication Hardware Accelerator means communicatively coupled with the Package Interconnect; an Extended Euclidian Algorithm Hardware Accelerator means communicatively coupled with the Package Interconnect; and a Fischer-Yates Shuffle Algorithm Hardware Accelerator means communicatively coupled with the Package Interconnect.

Shapeshift data encryption methods and systems

A storage system includes a plurality of storage devices in a storage chassis and configured to store objects, an Ethernet switch in the storage chassis, a Baseboard Management Controller (BMC) connected to the storage devices, and a memory connected to the BMC. The plurality of storage devices include a query storage device and a candidate storage device, and the storage devices are connected to each other via the Ethernet switch in the storage chassis. The memory or the query storage devices is configured to store metadata corresponding to the objects stored in the candidate storage device.

Method of distributed lookup in a storage device and system employing the method

A system and method for performing erasure code data protection and recovery computations using simple arithmetic and data manipulation functions. Other embodiments set forth techniques for using the computation functions with a multiplicity of compact one-dimension table lookup operations. A set of assigned multi-threaded processor threads perform computations on data values in parallel to generate erasure code data protection information and to perform data recovery operations using available data and the data protection information. During normal operations, in one embodiment, threads may perform parallel computations using a small set of simple arithmetic operations and data manipulation functions. In other embodiments, the threads may also use a multiplicity of compact one-dimension lookup tables stored within the multi-threaded processor or otherwise accessible by the multi-threaded processor to perform the computations.

Erasure code data protection and recovery computation system and method

A system and method for using a Solid State Drive (SSD) () are described. Reception circuitry () may receive write requests () and invalidate requests () from a first stream (). The write requests () may request that data be written to storage () on the SSD (); invalidate requests () may invalidate data written to the storage (). A statistics calculation logic () may calculate statistics () for the stream based on the write requests () and the invalidate requests (). A performance logic () may use the calculated statistics () to improve the performance of the SSD ().
