Space savings reporting for storage system supporting snapshot and clones
A technique efficiently determines accurate storage space savings reported to a host coupled to a reference-counted storage system that employs de-duplication and compression, wherein the storage space savings relate to snapshots and/or clones supported by the storage system. The snapshot/clone may be represented as an independent volume, and embodied as a respective read-only copy (snapshot) or read-write copy (clone) of a parent volume. Metadata is illustratively organized as one or more multi-level dense trees, wherein each level of each dense tree includes volume metadata entries for storing the metadata. The metadata is illustratively embodied as mappings from LBAs of a LUN to extent keys. Space adjustment counters, such as clone space adjustment (CSA) and diverged space adjustment (DSA) counters, may be employed when determining the storage space savings. The CSA counter is equal to the sum of mapped storage space across all levels of a dense tree. The DSA counter for the clone and for the snapshot equals the total mapped storage space in the level. The storage space savings may be determined by computing a value equal to the addition of the CSA counter to the total amount of data and metadata written to the LUN minus the DSA counters and, thereafter, dividing the value by the total amount of de-duplicated and compressed data for the LUN that is physically stored. |

Method for improving the ventilation effectiveness of large conditioned air plenum environments including such environments in multilevel raised floor electro-mechanical distribution systems
The present invention is intended for use in large conditioned air plenum environments and particularly in the plenum environment of multilevel raised floor electro-mechanical distribution systems. The invention comprises the step of providing at least one height change of dedicated conditioned air plenum, which alters the plenum's volume. This makes it possible to maintain the preferred static pressure and velocity for conditioned air throughout the entire plenum even as the amount of air in the plenum decreases as conditioned air discharges into the intended space outside of the plenum. |

Acoustic attenuation structure
An acoustic attenuation structure comprises a gas permeable composite facesheet, a cellular core, and an impermeable backing. The gas permeable composite facesheet has a designated porosity. The designated porosity causes the permeability of the gas permeable composite facesheet. The gas permeable composite facesheet comprises a carbon fiber fabric. The cellular core is bonded to the gas permeable composite facesheet using a resin of the gas permeable composite facesheet without any additional adhesive. The impermeable backing is connected to the cellular core. |

Integrated joint sealing system
An integrated joint sealing system that is incorporated into the edges of a sheathing panel, which also may have a factory bonded weather resistive barrier. The edges of each panel are configured as a shiplap joint, or similarly functioning joint, that is present as either an overlap or underlap on each of the four panel edges. The arrangement of the joints are such that one edge will have an overlap and the opposite edge will have an underlap. A flexible gasket material (or materials) is factory applied to one or both sides (underlap and/or overlap) of the shiplap joint. This flexible gasket material, when overlapped with adjacent shiplap panels, provides a weather resistive seal to limit both water and air penetration. |

Method and apparatus for cleaning large pipes, such as storm drain conduits
Apparatus and a method for cleaning accumulated sediment from storm drain conduits and other large-diameter conduits. A nozzle assembly is arranged to deliver a high-volume flow of water at a pressure high enough to loosen sediment from the interior of a conduit and to propel the nozzle assembly and an associated nozzle feed hose upstream within a conduit being cleaned. Water from the nozzle assembly flushes the sediment downstream and is then collected, partially cleaned, and reused in the nozzle assembly. Mud and clay may be left in the water to increase its specific gravity and viscosity. A self-contained portable and mobile system includes a tank and apparatus for removal of high concentrations of entrained or suspended solids, and a pump and conduits for delivering a high-volume flow of water, containing quantities of suspended solids, to the nozzle assembly. |

In-line partitioned separator storm water drain treatment system with upflow filter
A system designed to control and filter runoff water in storm drains is presented. Drain water frequently carries trash, organic matter, suspended solids, hydrocarbons, metals, nutrients and bacteria collected from streets and parking lots into a storm drain inlet, which enters storm water drain pipe systems.The present invention supplies a series of baffle boxes inserted in the drain water stream with a final box possessing an upflow filter comprising filtration media and filter cartridges. The system can also support a storm flow bypass that directs high-flow storm runoff water directly to the outlet to protect the filter system. |
