Abstract: A capillary pressure measurement device includes a centrifuge having a rotating apparatus adapted to hold porous media samples and to test the samples under centrifugal motion during rotation of the rotating apparatus. A fluid capture device disposed adjacent to each porous media sample receives fluid displaced from the sample due to centrifugal motion applied to the sample during rotation. A measurement system measures an amount of fluid displaced from the porous media samples by taking an image of a fluid meniscus in the fluid capture device. A position sensor determines a position of the fluid capture device and triggers a camera to take the image of the fluid meniscus when the fluid meniscus is in a field of view of the camera. The image of the fluid meniscus is processed to determine a fluid volume correlated to capillary pressure of the corresponding porous media sample.

Abstract: A measurement device including a centrifuge for holding porous media samples configured to test samples under centrifugal motion during rotation. A fluid capture device adjacent each media sample receives fluid from the sample due to centrifugal motion. A measurement system measures an amount of fluid from the media samples by taking an image of a fluid meniscus in the fluid capture device. A position sensor determines a position of the fluid capture device and triggers a camera to take the image of the fluid meniscus when the fluid meniscus is in a field of view of the camera. To prevent a false image from appearing in the captured image, a shield blocks light from reaching the camera when the meniscus is not in the field of view. The image of the fluid meniscus is processed to determine a fluid volume correlated to capillary pressure of the media sample.

Abstract: A system and method for offloading network processes from main processors of a storage system and performing them on parallel processing modules. Embodiments of the present invention improve performance of a clustered storage system by performing certain network processes in an accelerator module of a storage system node. The accelerator module receives multi-protocol protocol data units (PDUs) from a network interface, performs protocol operations on the PDUs to form file system requests and passes the file system requests to a local D-module. If a file system request is directed to a non-local D-module in the cluster, the accelerator module repackages the request for transmission to the appropriate D-module and passes it back to the network without using local D-module processing resources or passing data over the system bus.

Abstract: A system and method for offloading network processes from main processors of a storage system and performing them on parallel processing modules. Embodiments of the present invention allocate resources such as memory and/or buffers to particular connections between various storage operating system processes or between storage operating system processes and a network interface. Connections are identified by a connection identifier (CID) and are assigned particular buffers according to parameters such as buffer availability, connection priority, and/or maximum allocation thresholds. A connection associated with a CID is guaranteed access to a certain number of dedicated buffers. Deadlock is avoided even when an operating system process associated with a different CID attempts to exhaust available memory and/or buffers because such processes will only have access to their own allocated resources.
