  • Patent number: 11939563
    Abstract: A continuous automated perfusion culture analysis system (CAPCAS) comprises one or more fluidic systems configured to operate large numbers of biodevices in parallel. Each fluidic system comprises an input reservoir plate for receiving media; a biodevice plate comprising an array of biodevices fluidically coupled to the input reservoir plate, configured such that each biodevice has independent media delivery, fluid removal, stirring, and gas control, and each biodevice is capable of continuously receiving the media from the input reservoir plate; and an output plate fluidically coupled to the biodevice plate for real-time analysis and sampling. The operations of the CAPCAS are automated and computer-controlled wirelessly. The CAPCAS can also be used for abiotic and biotic chemical synthesis processes.

  • Patent number: 10133513
    Abstract: A method, computer program product, and computing system for determining a queue depth and a flush rate for each of a plurality of pending data queues associated with a cache system, thus defining a queue depth/flush rate pair for each of the plurality of pending data queues. A predicted drain time is determined for each of the plurality of pending data queues based, at least in part, upon the queue depth/flush rate pair, thus defining a plurality of predicted drain times that are respectively associated with the plurality of pending data queues.

  • Patent number: 9916244
    Abstract: Improved techniques for maintaining cache coherence in a consistent state are provided. These techniques implement a data storage system using a journaled mirrored cache that ensures that storage operations making up certain transactions be performed atomically, so that a system failure does not result in data loss. The improved techniques also allow for efficient communication of mirroring information.

  • Patent number: 9323671
    Abstract: A method and system for use in managing enhanced write caching is disclosed. In at least one embodiment, the method and system comprises performing write-back caching operations using a write cache of a storage processor of a data storage system. A first cache page corresponding to a disk location is provided in the write cache. A host is allowed to write to a second cache page in the write cache corresponding to the same disk location. Both the first and second cache pages are maintained after acknowledging the write to the host.
