Abstract: There is disclosed a storage unit for high performance computing system, a storage network and a method of providing storage and of accessing storage. The storage unit includes an enclosure constructed and arranged to receive plural storage devices to provide high density, high capacity storage. The unit also includes a network connector and at least one integrated application controller constructed and arranged to run a scalable parallel file system for accessing data stored on the storage devices and providing server functionality to provide file access to a client via the network connector.

Abstract: In conventional systems the CPU is altered after a data frame has been received and the packet stored in a host buffer. This interrupts normal operation of the CPU and applications, which is determined to systems performance. The invention relates to a method of transferring data from a network to a host using a network analyzer card, where a plurality of data frames from a network link is received and a descriptor is added to the frame. The descriptor includes data about the frame; each data frame and its or their attached descriptor is transferred to a host memory.

Abstract: A direct memory access controller includes a source memory controller for controlling a source memory, a destination bus controller for controlling the transfer of data to a destination memory, a first-in-first-out memory buffer for receiving data from the source memory, and a filter connected upstream of the first-in-first-out memory buffer for comparing the source memory data to a filter criterion and passing to the first-in-first-out memory buffer only that data which matches the filter criterion.

Abstract: A method and system for partial reassembly of data frames reconstructed from data cells received from a network data stream includes partially reassembling the header cells and the last cell of each frame and passing the remainder of data frame cells to a capture buffer in an unassembled state. Since the partially reassembled data frames include only a subset of each frame, they can be processed at the full line-rate of the network data stream without causing an overflow. The cells in the partially reassembled frames are only those cells required for functions that must be performed at the full line rate.
