摘要： An port expander Fibre Channel switch presents F_ports to form a first Fibre Channel fabric and N_ports to a second Fibre Channel fabric to appear as node devices. The port expander may be used to connect a plurality of blade servers to a Fibre Channel fabric. Fabric events engendered by the insertion or removal of hot-pluggable devices are handled by the port expander and “event storms” on the Fibre Channel fabric are avoided. The port expander presents the blade servers to the FC fabric as a virtualized N_port.

摘要： The snapshot capability moving into the SAN fabric and being provided as a snapshot service. A well-known address is utilized to receive snapshot commands. Each switch in the fabric connected to a host contains a front end or service interface to receive the snapshot command. Each switch of the fabric connected to a storage device used in the snapshot process contains a write interceptor module which cooperates with hardware in the switch to capture any write operations which would occur to the snapshot data area. The write interceptor then holds these particular write operations until the original blocks are transferred to a snapshot or separate area so that the original read data is maintained. Should a read operation occur to the snapshot device and the original data from requested location has been relocated, a snapshot server captures these commands and redirects the read operation to occur from the snapshot area. If, however, the read operation is directed to the original drive, the read is provided from the original data areas, even if the data had been replaced. The snapshot server determines the existence of particular snapshot devices, allocates their storage locations, provides this information to both the service interfaces and the write interceptors and handles read and write operations to the snapshot device.

摘要： A network configuration device or entity has control of defined management and security functions in the network, or in many embodiments, in a Fibre Channel fabric. The network configuration device may control many functions. Foremost, it may control the recognition, operation and succession procedure for network configuration entities. It may also control user configurable options for the network, rules for interaction between other entities in the network, rules governing management-level access to the network, and rules governing management-level access to individual devices in the network. In addition, the network configuration entity may exploit policy sets to implement its control.

摘要： A method and apparatus for securing networks, focusing on application in Fibre Channel networks. A combination of unique security techniques are combined to provide overall network security. Responsibility for security in the network is assigned to one or more designated entities. The designated entities deploy management information throughout the network to enhance security by modifying the capabilities and operational permissions of the devices participating in the network. For example, through network control: logical management access or physical I/O access may be limited on a per device or per I/O basis; and all devices and ports in the network operate only with other approved devices and ports. These designated entities can better manage network security by exploiting a unique link authentication system as well as a unique push-model secure distributed time service. The link authentication involves a multi-phase nonce exchange exploiting various derivations of the nonce and other information such as hashes and encryptions. The push-model secure time distribution departs from the traditional Fibre Channel pull mode time distribution and provides for secure and reliable distributed time so that various security attacks may be defeated.

摘要翻译：一种用于保护网络的方法和设备，专注于光纤通道网络中的应用。结合独特的安全技术，提供整体网络安全。将网络中的安全责任分配给一个或多个指定实体。指定实体在整个网络中部署管理信息，通过修改参与网络的设备的功能和操作许可来增强安全性。例如，通过网络控制：逻辑管理访问或物理I / O访问可能在每个设备或每个I / O的基础上受到限制; 并且网络中的所有设备和端口仅与其他已批准的设备和端口一起工作。这些指定实体可以通过利用独特的链路认证系统以及独特的推模型安全分发时间服务来更好地管理网络安全。链路认证涉及利用随机数的各种推导和其他信息（如散列和加密）的多阶段随机交换。推模型安全时间分配与传统的光纤通道拉模式时间分布不符，提供了安全可靠的分发时间，从而可能会破坏各种安全攻击。
