摘要： A system, computer program product and method for servicing requests. A server may be configured to receive a stream of requests to access particular logical block addresses in one or more logical drives in a RAID from one or more clients. The server may be coupled to one or more RAID adapters that are coupled to the RAID. The server may comprise a software RAID and each RAID adapter may comprise a hardware RAID. By monitoring the utilization of the processors in the server and in each RAID adapter, all or part of these received requests may subsequently be routed to either the software RAID or the hardware RAID based on which implementation is more desirable to service these requests.

摘要： Aspects of the invention provide an improved solution for processing packets in a packetized communications network. For example, a next packet in a set of incoming packets placed in a plurality of queues is selected by obtaining a random/pseudo-random search key and identifying one of the plurality of queues based on the search key and a Patricia tree that includes at least one child node for each of the plurality of queues. A greedy algorithm can be used to select an alternative queue should the first selected queue be empty.

摘要： A system, computer program product and method for reconfiguring a cache. A cache array may be created with one or more stacks of cache entries based on a workload. The one or more stacks may be ordered from most frequently used to least frequently used. The cache entries in each particular stack may be ordered from most recently used to least recently used. When a cache hit occurs, the cache entry requested may be stored in the next higher level stack if the updated frequency count is associated with the next higher level stack. When a cache miss occurs, the cache entry in a least recently used stack position in the stack with the lowest number of cache hits in the one or more stack positions tracked during a particular period of time may be evicted thereby allowing the requested information to be stored in the lowest level stack.

In one embodiment of the invention, a network traffic generation method can be provided. The method can include defining multiple, different scales in an n-state MMPP model to accommodate a full characteristic response of a modeled traffic scenario. The method further can include establishing a transition window for each of the scales and determining a state through the transition window for selected ones of the scales. Finally, the method can include computing an inter-packet time according to the determined state for each of the selected ones of the scales and generating and transmitting packets for the selected ones of the scales utilizing a correspondingly computed inter-packet time.

摘要： A method and circuit for using signature analysis testing techniques without deriving start/stop and clock signals from the device under test. In this invention, a start signal is derived from the output data stream by configuring that data stream to indicate when the test stream begins. The stop signal is derived by counting the predetermined number of data bit cells to be measured and issuing the stop signal when the count is reached. Data clock pulses are derived as a fraction of test system clock pulses at a frequency approximately equal to the bit cell frequency. The data clock pulse is located at the midpoint of the bit cell time so that the data stream is clocked into the signature analysis tester at a stable point.
