摘要： According to the present invention, methods and apparatus are provided to allow efficient and effective aggregation of ports into port channels in a fibre channel network. A local fibre channel switch can automatically identify compatible ports and initiate exchange sequences with a remote fibre channel switch to aggregate ports into port channels. Ports can be aggregated synchronously to allow consistent generation of port channel map tables.

摘要： The disclosed embodiments support improvements in network performance in networks such as storage area networks. This is particularly important in networks such as those implementing virtualization. These improvements, therefore, support improved mechanisms for performing processing in network devices such as switches, routers, or hosts. These improvements include various different mechanisms which may be used separately or in combination with one another. These mechanisms include methods and apparatus for processing traffic in an arbitrated loop, performing striping to support fairness and/or loop tenancy, performing configuration of network devices such as switches to enable virtualization to be performed closest to the storage device (e.g., disk), ascertaining a CPU efficiency that quantifies the impact of virtualization on a processor, and configuring or accessing a striped volume to account for metadata stored in each storage partition.
摘要翻译：所公开的实施例支持诸如存储区域网络的网络中的网络性能的改进。这在执行虚拟化的网络中尤其重要。因此，这些改进支持在网络设备（如交换机，路由器或主机）中执行处理的改进机制。这些改进包括可以单独使用或彼此组合使用的各种不同的机制。这些机制包括用于处理仲裁环路中的业务的方法和装置，执行条带化以支持公平性和/或循环租赁，执行诸如交换机之类的网络设备的配置以使虚拟化最靠近存储设备（例如，盘）执行，确定量化虚拟化对处理器的影响的CPU效率，以及配置或访问条带卷以考虑存储在每个存储分区中的元数据。

摘要： Techniques for selecting authentication roles when establishing a link between devices in a secure network are provided. By assigning role levels to devices, devices may be more likely to assume a preferred role when establishing a link. For example, during a negotiation process, each device may establish a timer value based on their role level. Each device may initiate a timer with the timer value and, the device whose timer value expires first may assume a role as authenticator.

摘要： Disclosed are methods and apparatus for detecting anomalies in a storage area network (SAN). Provided are one or more anomaly type(s) and corresponding actions to be performed when the one or more anomaly types are detected. Traffic in the SAN is then inspected in order to detect the one or more provided anomaly type(s). When a one of the provided one or more anomaly type(s) is detected, one or more of the corresponding action(s) is performed. The provided anomaly type(s) may include one or more of the following: a read or write access pattern anomaly, excessive login or control requests, a bandwidth usage anomaly, a configuration anomaly, and a hardware anomaly. The provided corresponding actions may include logging and/or publishing the detected anomaly, enabling capture of the detected anomaly by an analysis device, re-authentication of a host that is responsible for the anomaly, disable access control for a host that is responsible for the anomaly, rate control of an anomalous link, and shut down of an anomalous link.

摘要： A method and apparatus for reducing off-focus radiation by modifying a shape of a rotating target anode disposed within a cathode grounded x-ray tube. The shape of the target anode body is modified such that surfaces of the target anode which could otherwise direct the greatest amounts of off-focus radiation toward an x-ray sensitive imaging device are angled or shortened so as to redirect the off-focus radiation away from a focal direction. These modifications to surfaces of the target anode body include modifying a front surface, a side or edge surface, and a back surface.
