Abstract: A method for more efficiently utilizing storage space in a redundant array of independent disks (RAID) is disclosed. In one embodiment, such a method implements a RAID from multiple storage drives. The RAID utilizes data striping with distributed parity values to provide desired data protection/redundancy. The distributed parity values are placed on selected storage drives of the RAID in accordance with a designated parity rotation. The method further adaptively alters the parity rotation of the RAID to provide an increased concentration of parity values in certain storage drives of the RAID compared to other storage drives of the RAID. This parity rotation may be adapted based on residual storage capacity in each storage drive, consumed space in each storage drive, or the like. A corresponding system and computer program product are also disclosed.

Abstract: A method for more efficiently utilizing storage space in a set of storage drives is disclosed. In one embodiment, such a method implements, in a set of storage drives, a first RAID utilizing data striping with distributed parity values. The method further implements, in a subset of the set of storage drives, a second RAID using residual storage space in storage drives belonging to the subset. Storage drives belonging to the subset may have a storage capacity that is larger than storage drives not belonging to the subset. In certain embodiments, the method adaptively alters a parity rotation of the first RAID to provide an increased concentration of parity values in certain storage drives of the first RAID compared to other storage drives of the first RAID. A corresponding system and computer program product are also disclosed.

Abstract: An system and method for forming an elevated deck and support beam within a structure enables the pouring of one or a succession of superposed decks above a surface such as a floor, the ground or other supporting surface. The system includes a plurality of profiles which alone or in combination define concrete-receiving reservoirs for forming poured in place support beams, with the elevated deck being poured contemporaneously therewith for support on the beams. The profiles include first and second preferably divergent sidewalls which are connected by middle member which serves as a base or bridge between the sidewalls. The profiles are complementally configured to nest with one another to provide a span across structural walls, and may be provided with complementally configured end caps.
