Abstract: A method for minimizing latency of data transfer between the redundant storage controllers in a network-based storage controller system that utilizes adaptive data throttling. Each redundant storage controller monitors latency for round trip communications between the redundant controllers by calculating a time required to mirror a write to the other controller and receive a write acknowledge. An average latency for round trip communications between the redundant controllers during a fixed monitoring period is calculated, and at the end of each fixed monitoring period, the average latency is compared to a fixed latency to access the average time latency for mirroring writes is good, acceptable or unacceptable. If the average time latency is good, the one controller reduces or disables throttling for data transfers between the one controller and the server, and between the one controller and back-end storage, increasing a number of this type of data transfer that can be executed in parallel. If the average time latency is acceptable, the one controller does not adjust throttling for data transfers between the one controller and the server, and between the one controller and back-end storage. If the average time latency is unacceptable, the one controller increases data throttling for data transfers between the one controller and the server, and between the controller and the back-end storage, decreasing a number of this type of data transfer that can be executed in parallel.

Abstract: There are provided a method, a system and a computer program product for minimizing data transfer latency between redundant storage controllers in a network-based storage controller system that utilizes adaptive data throttling. Each corresponding redundant storage controller calculates average time latency for round trip communications between the corresponding redundant storage controller and the other redundant storage controllers during a fixed monitoring period. The corresponding redundant storage controller, at the end of each fixed monitoring period, compares the average time latency to a fixed latency. The corresponding redundant storage controller selectively throttles data transfer between the corresponding redundant storage controller and a server and data transfer between the corresponding redundant storage controller and a back-end storage, based on the comparison.

Abstract: A method and apparatus for recovery from faults in a loop network (500) is provided. The loop network (500) has a plurality of ports (520, 530, 532, 534) serially connected with means for bypassing the ports (520, 530, 532, 534) from the loop network (500). A control device (522, 524) is provided with bypass control over at least one of the ports (530, 532, 534). A host means (502) sends a command to the control device (522, 524) at regular intervals and the control device (522, 524) has a counter which restarts a time period at the receipt of each command. If the time period expires, the control device (522, 524) activates the means for bypassing all the ports (530, 532, 534) under its control. The loop network (500) may have two loops (516, 518) with at least some of the ports (520, 530, 532, 534) common to both loops (516, 518).

Abstract: An arrangement and method for update of configuration cache data in a disk storage subsystem in which a cache memory (110) is updated using two-phase (220, 250) commit technique. This provides the advantage that known changes to the subsystem do not require an invalidate/rebuild style operation on the cache. This is especially important where a change will invalidate the entire cache.
Abstract translation: 一种在盘存储子系统中更新配置高速缓存数据的装置和方法，其中使用两阶段（220,250）提交技术来更新高速缓冲存储器（110）。 这提供了对子系统的已知更改不需要高速缓存上的无效/重建样式操作的优点。 这在更改会使整个缓存无效的情况下尤其重要。

Abstract: Braking and centering mechanisms for foot-deck-based vehicles are described. At least one of the at least one rear wheel of the foot-deck-based vehicle is a braking wheel that is pivotally connected to the foot-deck for swivel movement about a rear swivel axis through a range of angular positions. The braking mechanism comprises a brake member coupled to the rear end of the foot-deck. The brake member is configured to move between a braking position in which the brake member is depressed towards the braking wheel and drives a brake surface to a frictionally engaging position at which the brake surface frictionally engages the braking wheel to reduce a speed of the foot-deck-based vehicle regardless of the angular position of the braking wheel within the range, and a non-braking position in which the brake member permits movement of the brake surface away from the braking wheel.
