摘要:
A path selection module selects at least two fibre channel paths between a fibre channel host and a fibre channel destination. A trace route module performs one or more fibre channel trace route procedures for each of the at least two fibre channel paths. The trace route module provides a set of fibre channel links between the fibre channel host and the fibre channel destination for each of the at least two fibre channel paths. A record registration module registers with one or more event servers to receive link incident records for the fibre channel links in the sets of fibre channel links.

Simulating latency in a network environment. A first device receives a latency request. The first device sends a latency support confirmation. The first device receives an I/O frame. The I/O frame comprising a latency simulating bit and a latency duration. Based on the latency simulating bit and the latency duration, holding, by the first device, the I/O frame. The first device sends the I/O frame on.

Exemplary method, system, and computer program embodiments for managing a network are provided. In one embodiment, at least one of an available plurality of network components is polled, including devices, hosts and virtual devices, an interconnected plurality of communication paths, and quality of service (QoS) information in a discovery process for network information. A graphical representation of the at least one of the available plurality of network components is created for presentation by a graphical user interface (GUI) to a user. Based on a selection of the user of at least one attribute of the at least one of the available plurality of network components as displayed by the GUI to the user, a zone is created for the at least one of the available plurality of network components.
摘要:
An apparatus, system, and method are disclosed for detecting intermittent network link failures. A tracking module tracks link failures of a network link of a network over a specified time interval. A failure module determines the network link is failing in response to a number of link failures exceeding a specified failure threshold. A mitigation module mitigates communications over the network link.

According to one embodiment, a system for creating a list of related defects in a network environment includes a processor, and a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code includes computer readable program code that, when executed by the processor, causes the system to acquire a device list related to devices in multiple paths of a network, computer readable program code that, when executed by the processor, causes the system to query one or more information sources using the device list to retrieve defect data from the one or more information, sources, computer readable program code that, when executed by the processor, causes the system to create a list of related defects based on the retrieved defect data, and computer readable program code that, when executed by the processor, causes the system to output the list of related defects.
摘要:
An approach to cable management is presented. A bi-stable liquid crystal display that requires no power to maintain an image is attached to a communications cable. A bi-stable liquid crystal display may be attached to each end of the cable. The bi-stable liquid crystal displays may be built into the connectors. A display module connects to the bi-stable liquid crystal display and receives signals associated with a message about the communications cable. The display module causes messages to be shown on the bi-stable liquid crystal display in response to receiving the signal. The signal may be generated by a user with a hand held driver. The signal may also be generated automatically by computing devices (such as switches) that are attached to the communications cable. Users may easily determine information about the communications cable by looking at the messages on the bi-stable liquid crystal displays.

In one embodiment, a method for testing a cable includes receiving a read-signal profile read at a receiving-end of a cable upon an initial test signal being input to a sending end of the cable, calculating a cross-correlation function between the read-signal profile and a matched filter output, and determining a peak value of the cross-correlation function. In another embodiment, a system includes a device, the device including logic for receiving a read-signal profile read at a receiving-end of the cable upon an initial test signal being input to a sending end of the cable, logic for calculating a cross-correlation function between the read-signal profile and a matched filter output, logic for determining a peak value of the cross-correlation function, and logic for storing the peak value to a computer readable medium. Other methods, systems, and computer program products are also described according to various embodiments.
