Abstract: A liquid potential energy increasing device includes a first receiving trough, a second receiving trough, a liquid absorbing structure, a first magnetic component, and a second magnetic component. The liquid absorbing structure includes a main body portion and an extending portion. The extending portion conveys a liquid in the first receiving trough into the main body portion. When a sum of a weight of the main body portion and a weight of the liquid in the main body portion is greater than the magnetic attraction, the main body portion hits the second receiving trough by gravity, so that the liquid in the main body portion is at least partially released to the second receiving trough so as to increase potential energy of the liquid.

Abstract: A storage virtualization computer system. The storage virtualization computer system comprises a host entity for issuing an IO request, a storage virtualization controller coupled to the host entity for executing IO operations in response to the IO request, and a at least one physical storage device, each coupled to the storage virtualization controller through a point-to-point serial-signal interconnect, for providing storage to the storage virtualization computer system through the storage virtualization controller. As an example, the point-to-point serial-signal interconnect can be a Serial ATA IO device interconnect.

Abstract: A JBOD subsystem for providing storage to a host entity. The JBOD subsystem contains at least one external JBOD emulation controller coupled to the host entity for emulating IO operations in response to the IO requests and a set of at least one physical storage device coupled to the JBOD emulation controller for providing storage to the host entity through the JBOD emulation controller. The JBOD emulation controller defines at least one logical media unit (LMU) consisting of sections of the set of physical storage device (PSD) and communicates with the PSD through a point-to-point serial-signal interconnect. As an example, the point-to-point serial-signal interconnect can be a Serial ATA IO device interconnect.

Abstract: A redundant external storage virtualization computer system. The redundant storage virtualization computer system includes a host entity for issuing an IO request, a redundant external storage virtualization controller pair coupled to the host entity for performing an IO operation in response to the IO request issued by the host entity, and a plurality of physical storage devices for providing storage to the computer system. Each of the physical storage devices is coupled to the redundant storage virtualization controller pair through a point-to-point serial signal interconnect. The redundant storage virtualization controller pair includes a first and a second storage virtualization controller both coupled to the host entity. In the redundant storage virtualization controller pair, when the second storage virtualization controller is not on line, the first storage virtualization controller will take over the functionality originally performed by the second storage virtualization controller.

Abstract: A method for efficiently storing data into a data storage system containing parity data comprises the steps of: determining the data storage units and the portions of each data storage unit where the data will be stored; determining the number of times the data units are accessed to calculate parity data for the new data, to store the new data, and to store the parity data using the complementary mode; determining the number of times the data units are accessed to calculate parity data for the new data, to store the new data, and to store the parity data using the noncomplementary mode; comparing the number times the data units are accessed using the complementary mode to the number of times the data units are accessed using the noncomplementary mode; calculating the parity data with the mode that requires the fewest number of accesses; and storing the calculated parity data and the new data in the data storage units.
