Persistent file system objects for management of databases
In a mirrored database system, a careful write of intentions to perform file system actions is recorded in a persistent file system objects table that is flushed to disk prior to the actions being taken.

Techniques for increasing storage system performance in processor-bound workloads with large working sets and poor spatial locality
An improved technique involves processing a workflow in stages, and processing all requests in a queue for a given stage before moving onto the next stage. Along these lines, each request received by a storage processor is assigned to a core and placed in a first queue for that core. Within that core, a single system thread executes first instructions for a task, e.g., checking the storage cache for the requested data from a request, and then transfers the request to a second queue. Rather than perform additional tasks to completely satisfy the request, however, the thread executes the first instructions for a prespecified number of requests in the first queue. Only when the thread has executed instructions for the prespecified number of requests, the thread begins execution of second instructions for requests in the second queue, and work on the next task begins. |

Differential limiting device for vehicle
In a differential limiting device for a vehicle, when rotary motion of an electric motor is converted by a screw mechanism into linear motion of a nut member in a direction of a first axis C1 of a side gear shaft, and a piston mounted on the nut member is moved in a direction opposite to a direction to depress frictional engagement elements, the piston and a clutch drum are relatively non-rotatably engaged. Therefore, differential rotation of a pair of side gears is mechanically limited. Thus, rotation of one electric motor makes it possible to generate differential limiting torque for limiting differential rotation of the pair of side gears in a rear-wheel differential device. |
