A lamp assembly provides light in a downward direction as well as in an upward direction through the use of angled housing walls and windows in the lamp assembly housing. Modularity and sliding elements enable the lamp assembly to be easily assembled and also easily repaired. A back cover on the lamp assembly is configured such that the lamp assembly is easily installed. Lamp heat management includes active and passive elements.

A system and method of providing enhanced data processing and analysis in a storage device, such as a solid state drive (SSD). The SSD includes flash memory and an SSD controller capable of executing searches on the data in the flash memory without returning all of the data to be searched to a host CPU outside of the SSD. Other processing capabilities incorporated into the SSD may include encryption and decryption, compression and decompression, and in-line indexing of data. The SSD efficiently processes queries through the use of an internal data buffer and a data engine configured to search partial data.

Systems and methods for performing search and complex pattern matching in a solid state drive

System and methods for enhanced data processing and analysis in a storage device, such as a solid state drive (SSD) include an SSD having a data storage and a controller. The data storage stores a plurality of data sets. The controller has a pattern buffer and a data engine. The controller receives a query, processes the query to extract a pattern, loads the pattern into the pattern buffer, and accesses the data storage. The data engine searches a data subset from the data storage for instances of the pattern using a rolling window method. The controller generates a result from the search.

A thermal interface material (TIM) pad is disclosed for dissipating heat from a component. The TIM pad includes a plurality of thermal interface material layers and at least one graphene layer interposed between the plurality of TIM layers. A method for forming the TIM pad includes stacking the plurality of TIM layers with at least one graphene layer interposed between the plurality of TIM layers to reach a length for the TIM pad. The stacked layers are cut corresponding to a thickness for the TIM pad for compression against the component.

A system and method for operating a solid state drive (SSD) within power limitations while maintaining SSD performance. In one embodiment a power management integrated circuit (PMIC) is used to measure power consumption, and a built-in self-test (BIST) procedure is used to exercise the storage device, and to calibrate the power consumed by various SSD operations. The results are stored in a power consumption cost table. In one embodiment, a procedure to dynamically adjust the power consumption cost table is employed. A power credit allocation scheme is used, along with the power consumption cost table, to track and limit the power consumed by the SSD in operation.

Dynamic self-correcting power management for solid state drive

A system and method for storing infrequently accessed data with reduced power consumption. In one embodiment, a solid state drive (SSD) includes flash memory and environmental data logging circuitry. The SSD is shut off or operated in a sleep mode to reduce power consumption, and turned on or transitioned to an active mode as needed when data on the SSD is to be accessed, or when a calculation, based on a number of erase cycles previously performed in the flash memory and on a temperature history of the SSD indicates that a data refresh may be needed to prevent data corruption in the SSD, due to data retention limitation of the nonvolatile memory in the SSD.

System and method for performing efficient processing of data stored in a storage node

A system and method of providing enhanced data processing and analysis in an infrastructure for distributed computing and large-scale data processing. This infrastructure uses the Hadoop&#x2122; framework to divide an application into a large number of small fragments of work, each of which may be performed on one of a large number of compute nodes. The work may involve map tasks and reduce tasks which may be used to categorize and analyze large amounts of data in distributed systems. This infrastructure includes a cluster with a master node and a plurality of slave nodes. The slave nodes may include, or may be, intelligent solid-state drives capable of executing Map-Reduce functions. The use of intelligent solid-state drives reduces the need to exchange data with a CPU in a server.

A secure storage device includes a storage medium configured to securely store data received from a host. The storage device further includes a host interface configured to transfer data between the host and the storage device and an encryption engine. The encryption engine is configured to encrypt data received from a host using a key and provide the encrypted data to the storage medium for storage. The encryption engine is further configured to decrypt encrypted data received from the storage medium and provide the data to the host via the host interface. In response to a predetermined condition, the storage device is configured to disable the encryption engine thereby preventing the encrypted data stored thereon from being decrypted.
