Abstract: A log structured array (LSA) controller apparatus controls the transfer of information between a processor and a plurality of information storage devices configured as an N+1 array in which the information is stored as stripes extending across the devices of the array, each stripe comprising N information strips and one parity strip, each information strip storing an integer number of logical tracks. The controller defines an LSA directory that specifies the location of each logical track in terms of the ID of the stripe to which the track belongs and the offset of the track within the stripe; wherein on the addition of an information storage device to the array, the additional strip provided for each stripe by the storage device is logically appended to the end of each stripe in the LSA directory.

Abstract: A data storage system and method of storing data with at least two controllers (200, 300) which share a storage space (244, 344) on an array of storage devices and which support the same set of logical upstream devices. The controllers (200, 300) share the workload by dividing the shared storage space (244, 344) into stripes where the stripes are sufficiently small to divide the workload uniformly across the storage device. This is achieved in the case of two controllers (200, 300) of a log structured array by dividing the storage space into odd and even tracks, all odd tracks being designated to one controller (300) and all even tracks to the other controller (200).

Abstract: An improved shield which is readily attached or detached at the forward edge portion of a hood of a vehicle. The shield has a longitudinal member of flexible material laterally extending across the front edge of the hood. The longitudinal member has an upper section adapted to engage the upper surface of the hood and a lower section adapted to engage the underside of the hood. The longitudinal member further has a linking section linking the upper and lower sections and shaped to apply a spring force to the vehicle hood so that the vehicle hood is resiliently clamped between the upper and lower sections of the shield by the spring force.

Abstract: An aero deflector for vehicles including, for example, trucks, vans, and sports utility vehicles. In the illustrated embodiment, the aero deflector is molded from a single piece of material and has a plurality of air intakes and a conforming mounting flange which is attached to the vehicle surface by adhesive mounting tape.

Abstract: An air deflector which is securable to a roof of a vehicle having an opening for a sunroof, to deflect the flow of air over the vehicle when the vehicle is in motion and a method of securing the same. The air deflector comprises an elongate deflecting panel having a length at least as long as the forward edge of the sunroof opening, adhesive along one of the elongate edges of the panel to secure the panel to the roof, and a pair of end supports extending downwards from the ends of the panel to hold the panel at an angle relative the roof.
