Abstract: This disclosure uses both an administrative thread and multiple worker threads (N) to process the LUN on-lining work in parallel at both the volume level and the LUN level. When the administrative thread receives the message to start the initialization, the administrative thread assigns the work for reading the VTOC information for the LUNs in a volume to one or more worker threads and moves on to perform additional initialization tasks. N worker threads work on N volumes in parallel. These worker threads then independently send messages (e.g., asynchronous messages) to the file system layer, and once the file system layer is done loading the required buffers, the file system layer sends replies back to the administrative thread. The administrative thread then again assigns work to the worker threads to finally bring the LUNs on-line.

Abstract: A viscometer, comprising: a source of fluid pressure, a tube, an array of optical detectors, an acquisition driver circuit and viscosity computation logic. The tube has an inside volume that is hydraulically responsive to the source of fluid pressure. The array of optical detectors is positioned along a length of the first tube with a plurality of its detectors optically responsive to the inside volume of the first tube and including an image data output. The acquisition driver circuit is responsive to the image data output of the first array to acquire a series of successive images of the inside volume of the first tube. The viscosity computation logic is responsive to the acquisition driver circuit and operative to compute the viscosity of a fluid flowing along the first tube from the series of images of the inside volume of the first tube.

Abstract: A chamber in which an agent, like genomic DNA, may be harvested and optionally manipulated rapidly (e.g., on the order of a few hours), without shearing or fragmentation.

Abstract: An apparatus and a method for initializing data storage units of a volume or multiple volumes in parallel for data access as part of an initialization process. The method may include assigning initialization tasks for each of the data storage units to the multiple worker threads, and each of the worker threads independently performing each of the initialization tasks. The apparatus may include a processor and a memory storing instructions which configure the processor to initialize an initialization process to initialize the data storage units of a volume or of multiple volumes in parallel for data access.

Abstract: Aspects of the invention relate to devices and methods of use thereof for concentrating, positioning and/or manipulating agents within a fluid, including but not limited to genomic DNA.

Abstract: Method and system is provided for performing a failover operation during which a second storage system takes over the management of a storage volume managed by a first storage system. The first storage system may also manage a plurality of replicated copies of the storage volume and maintain metadata for storing information regarding the replicated copies. The failover operation is completed without having the second storage system read all the metadata.
