摘要： A reliable asymmetric method for distributing security information within a Fiber Channel Fabric. The Switching Fabric includes a set of security servers, which maintain among themselves a replicated copy of the Fabric security databases using the currently defined Merge and Change protocols. The other Switches of the Fabric are configured as client-Switches. They maintain only the subset of the authorization and authentication information required for their correct operation. A client-Switch queries the security server when a new end-device is connected to it, or when it is connected to the Fabric. When the security configuration of the Fabric changes by an administrative action, a security server solicits the client-Switches to update their information. In an alternative embodiment, the end-devices may query directly the security server, usually for authentication purposes. A Fabric with a plurality of security servers balances among them the load of inquiries from clients, and is more reliable because it continues to operate in the event of failure of one or more servers. Reliability is achieved in a stateless manner through the FSPF protocol, the Fiber Channel routing protocol. Each security server announces itself to the Fabric by advertising an adjacency to a predefined virtual Domain_ID in its FSPF LSRs. Clients access servers by directing queries to this virtual Domain_ID.
摘要翻译：一种用于在光纤通道结构中分发安全信息的可靠的非对称方法。交换结构包括一组安全服务器，它们使用当前定义的合并和更改协议在其中维护Fabric安全数据库的复制副本。 Fabric的其他交换机配置为客户端交换机。它们仅维护其正确操作所需的授权和认证信息的子集。客户端 - 交换机在新的终端设备连接到安全服务器或连接到Fabric时查询安全服务器。当Fabric的安全配置更改为管理操作时，安全服务器请求客户端 - 交换机更新其信息。在替代实施例中，终端设备可以直接查询安全服务器，通常用于认证目的。具有多个安全服务器的Fabric在其中平衡了客户端的查询负载，并且由于在一个或多个服务器发生故障的情况下继续运行而更加可靠。通过FSPF协议（光纤通道路由协议）以无状态的方式实现可靠性。每个安全服务器通过向其FSPF LSR中的预定义虚拟Domain_ID发布邻接关系，向Fabric发布自身。客户端通过将查询引导到此虚拟Domain_ID来访问服务器。

摘要： A fibre channel frame is received at a first fibre channel switch. The fibre channel frame includes time stamp information associated with fibre channel switches between a second fibre channel switch and the first fibre channel switch. A time-to-live (TTL) value included in the fibre channel frame is determined. The fibre channel frame is sent back to the second fibre channel switch upon determining the TTL value included in the fibre channel frame.

摘要： In one embodiment, a solution is provided wherein a lock client sends lock requests to a lock manager upon receipt of an input/output (I/O) and receives back a lock grant. At some point later, the lock client may send a lock release. The lock manager, upon receipt of a lock release from a lock client, remove a first lock request corresponding to the lock release from a lock grant queue corresponding to the lock manager. Then, for each dependency queue lock request in a dependency queue corresponding to the first lock request, the lock manager may determine whether the dependency queue lock request conflicts with a second lock request in the lock grant queue, and then may process the dependency queue lock request according to whether the dependency queue lock requires conflicts with a second lock request in the lock grant queue.

摘要： Data back-ups are a critical task of any information technology department. Data back-ups are typically performed using some type of back-up tape systems. Internet based data storage systems now offer data storage services at low prices. To take advantage of such services, a system and method for efficiently back-up data volumes is disclosed. The data back-up system divides data volumes into fingerprinted data slices. Redundant data slices are then removed. Unique fingerprinted data slices are then copied to an internet based storage provider.

摘要： A system and method for efficiently storing data both on-site and off-site in a cloud storage system. Data read and write requests are received by a cloud data storage system. The cloud storage system has at least three data storage layers. A first high-speed layer, a second efficient storage layer, and a third off-site storage layer. The first high-speed layer stores data in raw data blocks. The second efficient storage layer divides data blocks from the first layer into data slices and eliminates duplicate data slices. The third layer stores data slices at an off-site location.

摘要： In one embodiment, a solution is provided wherein a minimum and/or maximum bandwidth may be guaranteed for specific flows. These guarantees can be associated to various levels of granularity, such as target (T), target-Logical Unit Number (LUN) coupling (TL), initiator-target-LUN coupling (ITL), and initiator-target coupling (IT). This may be accomplished by rate limiting frames in the storage area network based upon quality of service information provided by a user. As such, the traffic can be shaped in a way that guarantees requested levels of service without dropping frames.

摘要： In one embodiment, a solution is provided wherein a lock manager is kept moving among multiple cores or processors in a multi-core or multi-processor environment. By “hopping” the lock manager from processor to processor, a bottleneck at any of the processors is prevented. The frequency of movement may be based on, for example, a counter that counts the number of input/outputs handled by the lock manager and moves the lock manager to a different processor once a determined threshold is met. In another embodiment of the present invention, the frequency of the movement between processors may be based on a time that counts the amount of time the lock manager has been operating on the processor and moves the lock manager to a different processor once a predetermined time is reached.
