  • Publication number: 20240302989
    Abstract: Described are techniques for application-consistent snapshots. The techniques include determining that a scheduled snapshot of a storage volume is imminent, where the storage volume stores input/output (I/O) data associated with an application that executes on a host server. The techniques further include initiating at least one host buffer flush prior to the scheduled snapshot being performed, where I/O data in a host buffer associated with the application is transferred to a write cache of the storage volume to reduce an amount of I/O data in the host buffer when performance of the scheduled snapshot begins. The techniques further include initiating, after the host buffer flush has completed, a write cache flush to write the I/O data in the write cache to the storage volume. The techniques further include initiating the scheduled snapshot of the storage volume in response to an indication that the write cache flush has completed.

  • Patent number: 11423575
    Abstract: A method of characterizing an imaging device includes calibrating the imaging device by collecting readings for regular pixels and at least one sealed pixel of the imaging device over one or more periods of time for a sequence of integration time (T) and a plurality of number of lines (NOL) when no light enters the imaging device, obtaining a dark level (DL) by averaging the readings for the regular pixels over the respective period of time and the number of the regular pixels, and obtaining P by averaging the readings of the at least one sealed pixel over the respective period of time and the number of the at least one sealed pixel. A relation between DL and P is determined for each T and NOL using an equation: DL=A*P+Offset. A current value of DL is determined by using a current value of P and the equation.
