Abstract: Embodiments herein relate to sending a request to a storage device based on a moving average. A threshold is determined based on a storage device type and a bandwidth of a cache bus connecting a cache to a controller. The moving average of throughput is measured between the storage device and a host. The request of the host to access the storage device is sent directly to the storage device, if the moving average is equal to the threshold.

Abstract: A switch fabric system comprises a first chassis for receiving a plurality of line cards each having a plurality of ports and at least two switch fabric cards wherein each line card comprises a plurality of link ports for linking the line card with the switch fabric card. Each switch fabric card provides a switching bandwidth. The system comprises a management unit for managing the traffic on the switch fabric cards wherein the management unit removes the traffic from one switch fabric card if the one switch fabric card is to be removed while the other switch fabric card operates and transfers the traffic to the other switch fabric card.

Abstract: A heterogeneous and scalable bridge capable of translating a plurality of network protocols is adapted for coupling to a network switch fabric. The bridge uses at least one egress buffer interface and can perform port aggregation and bandwidth matching for various different port standards. The bridge is adapted for both networking and storage area networking protocols. A control unit is implemented with the bridge is able to identify control and flow information from different protocols and adapt them to the respective interface to which they are to be transmitted. Accounting logic is provided to one or more of the elements of the apparatus to aid in the tracking, storing, and reporting of network traffic.

Abstract: A system and method for providing flow control for a computer network is disclosed. In one embodiment of the present invention, buffer-to-buffer credit flow control is implemented to limit the amount of data a port may send based on the number and size of the frames sent from that port.

Abstract: A computer network switch system is disclosed. A switch system may be configured as a single chassis system that has at least one line card, a set of active switch fabric cards to concurrently carry network traffic; and a first system control card to provide control functionality for the line card. The switch system may be configured as a multiple chassis system that has at least one line card chassis containing several line cards, and a switch fabric chassis (or a second line card chassis) that contains several switch fabric cards to provide a switching fabric with multiple ports. Load-sharing is accomplished primarily at the chip level, although card-level load-sharing is possible.

Abstract: A system and method for providing XON/XOFF port-level flow control for a computer network that has access to a plurality of network processors in communication with the computer network. At least one network processor has an egress port associated with an egress buffer, and a set of network processors is associated with a bridge.. XON/XOFF port-level flow control is implemented to halt and resume traffic directed to a congested port.
