摘要： Implementations are disclosed that provide protocols for connecting an intelligent service module within a storage area network (SAN). The protocols support physical connections between the intelligent service module and a director-level switch of the SAN. In some variations, the intelligent service module may comprise a director service module (DSM), a domain-sharing leaf switch service module (LSSM), or a non-domain-sharing LSSM. The protocols provide for establishing link parameters and negotiating responsibilities between the intelligent service module and the director-level switch. In one configuration, for example, ELP and ELP_ACCEPT frames may be used to establish the link parameters. In another configuration, ESC and ESC_ACCEPT frames may be used to negotiate responsibilities between the intelligent service module and the director-level switch. Other configurations also provide an ownership status of the intelligent service module that is used to determine whether the switch can initiate management of the intelligent service module.

摘要： A flexible architecture for embedded firmware of a multiple protocol switch can be implemented on a variety of hardware platforms. Hardware components of a SAN switch are embodied as cooperative modules (e.g., switch modules, port modules, service modules, etc.) with one or more processors in each module. Likewise, firmware components of a SAN switch can be assigned at initialization and/or run time across a variety of processors in any of these modules. The processors and firmware components can communicate via a messaging mechanism that is substantially independent of the underlying communication medium or the module in which a given processor resides. In the manner, firmware components can be reassigned (e.g., in a failover condition), added or removed without substantial disruption to the operation of the SAN.

摘要： A system and method for inserting intermix frames into a continuous stream of class 1 frames. A bypass bus, in conjunction with a buffer, are provided within a fiber optic switch element, to route intermix data frame through the switch that is concurrently transmitting class 1 data. A channel module, which is disposed between a switch module and a plurality of fiber optic channels, comprises a port intelligence system and a memory interface system. The port intelligence system is responsible for transmitting and receiving data from the fiber optic channels in accordance with a predetermined protocol, preferably Fibre Channel. The memory interface system comprises a receive memory unit, a transmit memory unit and memory control logic. When an intermix frame is to be passed through the switch, the intermix frame is passed to the buffer concurrently while class 1 data transfer occurs via the bypass bus. After the intermix frame has been completely written into the buffer, the memory control logic waits to detect a tag indicative of a break in the class 1 data transfer. The control logic will then switch the MUX and cause the buffer to commence writing the intermix frame to the port intelligence system for transfer to a predetermined fiber optic channel.

摘要： A method includes determining a priority of each of a plurality of frames, wherein the priority is a function of an initial value dependent on content of each said frame and one or more adjustment values independent of content of each said frame, and selecting the frame with the highest determined priority for transmission through the device prior to transmission of any other of the frames. A system includes a receiving port configured to receive frames and assign an initial priority to each frame, a queue configured to insert queue entries associated with received frames on the queue, each queue entry being inserted at a queue position based on the initial priority assigned to the queue entry, the queue further configured to reorder queue entries based on readjusted priorities of the queue entries; and a transmitter switch configured to transmit the frame having the highest priority before transmitting any other frame.

摘要： A multi-level content addressable memory (CAM) architecture compresses out much of the redundancy encountered in the search space of a single CAM, particularly for flow-based lookups in a network. Destination and source address may be associated with internal equivalence classes independently in one level of the multi-level CAM architecture, while flow-specific properties linking arbitrary classes of the destination and source addresses may be applied in a later level of the multi-level CAM.

摘要： Intelligent services are provided in a storage network using intelligent service modules that can be cabled to a switch external to the switch chassis and yet be managed as part of the switch's logical domain. Data and management communications between the intelligent service module and the core switch are provided through a “soft-backplane” implemented using in-band communications through cabling attached between the switch and the intelligent service module rather than through hardwired backplane within the chassis. Management communications from management software is directed to the switch, which handles the management functions relating to the intelligent service module or forwards the management requests to the intelligent service module for processing.
