Abstract: Methods and systems for managing access to a distributed storage systems include storing a total bandwidth utilization amount allocated to each of a plurality of client devices and a current bandwidth amount utilized by each of the plurality of client devices. An actual bandwidth amount utilized for servicing one or more requests received from a plurality of client devices over a network is monitored and an expected bandwidth utilization amount for servicing a request to access a distributed storage system having a plurality of storage devices interconnected over a network, received from respective ones of the plurality of client devices is determined. The client device transmitting the request is either permitted or denied access to the distributed storage system based on a function of the expected bandwidth utilization of the request relative to the total bandwidth utilization amount allocated to the requesting client device.

Abstract: A method of testing a double data rate (DDR) memory interface within a System-on-chip (SoC). The method comprises generating a data stream within the SoC and writing the data stream to an internal memory within the SoC via the DDR memory interface. The method further comprises reading the data stream from the internal memory within the SoC and comparing the data stream generated within the SoC with the data stream read from the internal memory within the SoC.
