    摘要： A storage virtualization system for accessing at least one storage device for a virtual logical unit (VLUN) from at least one host. The system includes at least one upstream processing element (UPE) which is adapted for coupling to a corresponding host server. The system is further adapted for coupling to at least one storage device. The controller also includes a primary central processing element (CPE) that can be configurably coupled to the UPEs. The primary CPE permits data transfer to occur between a host and a storage device via the corresponding UPE. The controller further includes a backup CPE that can be configurably coupled to the UPEs. The backup CPE is configurable to permit the data transfer when the primary CPE becomes unavailable.

    摘要： A storage virtualization controller for transferring data between a host and a storage device at a wire-speed data transfer rate. A downstream processing element adapted for connection to the storage device is configurable coupled to an upstream processing element adapted for connection to the host. A central processing element coupled to the upstream processing element grants permission to the upstream processing element to transfer the data at the wire-speed rate without further involvement by the central processing element.

    摘要： A Virtual Storage Server is provided for transferring data between a source storage device and one or more destination storage devices. A write command is issued to the one or more destinations for an amount of data. In response, one or more Transfer Ready Responses are returned indicating the amount of data the destinations are prepared to receive. The Virtual Storage Server then sends a read command to the source for an amount of data based on the amounts of data in the Transfer Ready Responses. The data is then transferred from the source storage device through the Virtual Storage Server to the one or more destination storage devices. Because data is transferred only in amounts that the destination is ready to receive, the Virtual Storage Server does not need a large buffer, and can basically send data received at wire speed. This process continues until the amount of data in the write command is transferred to the one or more destination storage devices.

    摘要： A method and apparatus for collecting information from ports on a storage network and performing flow control is provided. The data collection method and apparatus includes, identifying a data type transported on the storage network, selecting a port-storage identifier to measure the data type transported across the storage network, monitoring the port-storage identifier on the storage network for the data type, and enumerating occurrences of the data type associated with the port-storage identifier while monitoring the port-storage identifier and the data type. The flow-control operation receives information on a data type passing through the storage network according to a port-storage identifier, compares a threshold with the data type passing through the storage network according to a port-storage identifier, determines when the threshold associated with the data type has been exceeded in consideration of the information received, queues in response to the determination the data type scheduled to pass through one or more ports and storage devices identified according to the port-storage identifier on the storage network.

    摘要： A method and apparatus in a distributed processing environment for tracing events includes receiving a request to trace an event on a local processor, acquiring a sequence identifier associated with the local processor that associates the event with a chronological sequence of events on the local processor, storing the sequence identifier and information about the event in a local event trace associated with the local processor, providing the sequence identifer and information about the event to a remote processor for storage in a remote event trace. Consolidating the event traces from multiple processors into a single chronological event trace includes accessing a local event trace having one or more local trace events associated with the local processor, identifying a trace event entry having a local sequence identifier and referencing a remote processor, accessing a remote event trace associated with the remote processor and having a remote trace event entry matching the local sequence identifier, comparing the remote trace event entry with the local sequence identifier and one or more local trace events in the local event trace, and inserting the remote trace event entry into the local event trace based upon the comparison.
