摘要： One embodiment includes a system for application-layer monitoring of communication between one or more database clients and one or more database servers. The system includes one or more decoders residing at a decoding layer above a network layer. The decoders reside at a first network location between one or more database clients residing at one or more second network locations and one or more database servers residing at one or more third network locations. The decoders receive database messages communicated from the database clients and intended for the database servers and database messages communicated from the database servers and intended for the database clients, decode the database messages, and extract query-language statements from the database messages. The system also includes a monitoring application residing at an application layer above the decoding layer. The monitoring application resides at the first network location. The monitoring application receives query-language statements extracted at the decoders and records observations on the database messages based on the query-language statements extracted at the decoders.

摘要： According to one embodiment of the present invention, a controller that partitions a media library for multiple host applications can, for each partition, assign a base element address for an element type and associate physical element addresses for elements of an element type with an index value. For a partition, the logical element address corresponding to a physical element address for an element can be determined by adding the index number associated with the physical element address to the base element address for that element type. The physical element address corresponding to a logical element address for an element can be determined by subtracting the base element address for the element type from the logical element address for the element. The result of subtracting the base element address from the logical element address is an index value for which the associated physical element address can be found.

摘要： Systems and methods for distributing management information in a computing system over existing power are disclosed. These systems and methods may eliminate the need for a separate physical network to distribute management information in the computer system and the commensurate physical hardware need to implement these networks. A management system may place a management communication on a physical transport medium. This management communication may then be placed on the power lines used to power the various components of the computing system and distributed to the various components along these power lines, where it may be received by its intended recipient and acted upon if necessary.

摘要： A method and system for routing data across heterogeneous networks. In one embodiment, a heterogeneous network comprises a specialized in-band network that is privately accessible within the heterogeneous network, as well as an out-of-band network that is coupled to the in-band network by a switching platform. A client on the out-of-band network is configured to transmit a request for server data to the switching platform. The request is formatted according to the protocol of the out-of-band network and may take the form of a uniform resource locator (URL). The switching platform is configured to recognize the request as one which is directed to a server on the in-band network. The switching platform parses the request to determine the requested data and reformats this information as a new request that is transmitted to the server according to the protocol of the in-band network. The server provides data responsive to the new request, which is transmitted back to the switching platform according to the protocol of the in-band network. The switching platform then reformats the responsive data according to the protocol of the out-of-band network and transmits it to the client. The switching platform is separate from the default gateway and proxy servers.

摘要： A method and system are disclosed for encapsulating SCSI protocol for data transmission between two or more nodes across a packet-based network. The method of the present invention includes the steps of, at each node in the network, identifying all other available nodes on the network, and the remote devices attached to those nodes; representing one or more of the attached remote devices such that they are made available to the node's local hosts; encapsulating the I/O phases between one or more local hosts and one or more of the remote devices; and repeating the encapsulating step for subsequent I/Os between one or more hosts and one or more devices. The step of encapsulating I/O phases between a local host and a remote device can further comprise encapsulating task management functions, error recovery functions and normal I/O processing functions. Each node can be a Fibre Channel-to-SCSI router.

摘要： Systems and methods for automated testing of multiple-protocol network environments wherein data which is formatted according to a plurality of protocols in sequence is automatically identified and compared to determine whether the data has been correctly transformed from each protocol to the next. An indication of whether the data has been correctly transformed may be presented to a user, along with information about the data itself, such as commands which may be included therein. The information presented to the user is in a user-readable form rather than raw data in order to facilitate analysis of the information by the user.

摘要： The present invention provides a method and system for mapping addressing of SCSI devices between two SANs connected by a SAN extender over a packet-based network with use of a Fibre channel protocol over large distances. The present invention seamlessly interconnects graphically distinct SANs such that they operate as if they were local to one another by providing a means to generically and dynamically map SCSI device addresses between two SANs. The present invention provides a method and system for accessing a device from a host, wherein the host and device are in separate SANs interconnected by a transport layer, and wherein the interface between said transport layer and each of said SANs is a node. This method comprises, at each node, the steps of: mapping the device address into an intermediary device identifier, and mapping the intermediary device identifier into an address accessible by the host. Each node can be a Fibre channel-to-SCSI router, and the intermediary device identifier can comprise a node identifier and a generic device identifier. The transport layer can be a packet-based network.

摘要： Systems and methods for performing error recovery in a system utilizing redundant communication links. In one embodiment, a host device is coupled to a sequential device such as a tape drive by a pair of Fibre Channel links. The host is configured to associate an identifier with each command. Upon detecting a failure of the transmission of the command via the first link, the host re-transmits the command via the second link. When the link failure is detected, the status of the last command transmitted before the failure is requested. After receiving the status of the command, a request that recovery start (possibly at a point indicated by the status information) is transmitted to the sequential device. If the recovery request is accepted, performance of the command is completed.
