US Patent:

54530490, Sep 26, 1995

Filed:

Feb 23, 1994

Appl. No.:

8/200201

Inventors:

Bernard W. Tillman - Houston TX
Van B. Smith - Spring TX

Assignee:

Isolate, Inc. - Houston TX

International Classification:

F24F 316

US Classification:

454228

Abstract:

Air purification or filtration unit having a triangular housing, with the open front face being the hypotenuse of the triangle. The unit is particularly adaptable for use with conventional sized high efficiency particulate air, or HEPA filters and low penetration air, or ULPA filters, to create a highly filtered clean air environment. The unit includes a circulating fan within the housing to draw air through the filters and housing and to exhaust the air through the top housing wall for recirculation, and can also be ducted to exhaust filtered air from the environment, either in whole or in part. A germicidal ultra violet light may be placed within the housing for additional air purification.

International Classification:

G06F 11/10
G06F 11/20
G06F 3/06

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.

International Classification:

G06F 11/10
G06F 3/06

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.
