Abstract: A data storage system includes one or more hard disk drive systems and an air moving device. The hard disk drive systems may include one or more drive mechanical modules that store data and a drive control module electrically coupled to the drive mechanical modules. The drive control modules may control mechanical operations in the drive mechanical modules. The drive control module includes a circuit board assembly and heat producing components coupled to the circuit board assembly. Air passages on each side of the printed circuit board assembly allow a stream of air to flow across heat producing components on at least one side of the printed circuit board assembly.

Abstract: In a system in which documents are generated dynamically in response to user requests, historical data is collected regarding data retrieval subtasks, such as service requests, that are performed to generate such documents. This data is used to predict the specific subtasks that will be performed to respond to specific document requests, such that these subtasks may be initiated preemptively at or near the outset of the associated document generation task. A subtask that would ordinarily be postponed pending the outcome of a prior subtask can thereby be performed in parallel with the prior subtask, reducing document generation times. In one embodiment, the historical data is included within, or is used to generate, a mapping table that maps document generation tasks (which may correspond to specific URLs) to the data retrieval subtasks that are frequently performed within such tasks.

This data is used to predict the specific subtasks that will be performed to respond to specific document requests, such that these subtasks may be initiated preemptively at or near the outset of the associated page generation task. A subtask that would ordinarily be postponed pending the outcome of a prior subtask can therefore be performed in parallel with the prior subtask, reducing document generation times. In one embodiment, the historical data is included within, or is used to generate, a mapping table that maps document generation tasks (which may correspond to specific URLs) to the data retrieval subtasks that are frequently performed within such tasks.
