Abstract: A field oriented pipeline processor for a data engine that can be programmed to recognize record and field structures of data received from a source such as a mass storage device. The processor has an interface for receiving field-delineated data from a field parser. The field parser parses non-field delineated data from a streaming data source into field delineated data under instruction from an external processing unit. The pipeline processor receives a field delineated data stream and employs logical arithmetic methods to compare fields with one another, or with values otherwise supplied by general purpose processors to precisely determine which records are worth transferring to memory of the more general purpose distributed processors. The architecture of the data engine allows for the use of substitution tables, temporary registers, and a data string register to assist in the efficiency and accuracy of the data engine processing.

Abstract: A disk is segmented into a first data segment and a secondary data segment. The secondary data segment stores a logical mirror of the first data segment of another disk. Fast access to data stored on the disk is provided by partitioning the disk such that the first data segment includes the fast tracks of the disk and the secondary data segment includes the slow tracks of the disk and forwarding all data requests to the first data segment. Upon detecting a failure, the logical mirror of data stored in the first data segment of the failed disk is accessible from the secondary data segment of a non-failed disk. The first data segment can be rebuilt quickly on another disk from the logical mirror stored in the secondary data segment.

Abstract translation: 磁盘被分割成第一数据段和辅助数据段。 辅助数据段存储另一个磁盘的第一个数据段的逻辑镜像。 通过对磁盘进行分区来提供对磁盘上存储的数据的快速访问，使得第一数据段包括磁盘的快速轨道，次要数据段包括磁盘的慢磁道并将所有数据请求转发到第一数据段。 在检测到故障时，存储在故障磁盘的第一数据段中的数据的逻辑镜像可从非故障磁盘的辅助数据段访问。 可以从存储在辅助数据段中的逻辑镜像在另一个磁盘上快速重建第一个数据段。

Abstract: A hard disk drive (HDD) comprising an additional application-specific component for receiving and executing application-specific instructions. Standard ATA or SCSI hard disk drives comprise, at a minimum, a housing, rotating disk platters containing data, magnetic heads to read and write data to the rotating disks, and a controller circuit for operating the rotation of the disk and read/write functions of the magnetic heads. An additional component is added to this standard list of components, the additional component being capable of receiving application-specific instructions via a standard network connection and executing these application-specific instructions on the data contained on the rotating disks. The application-specific component may be in the form of an add-on board which couples to the controller circuit or, alternatively, in the form of an application-specific chip which mates with a socket provided on the controller circuit.
