摘要： An OSI layer 2 network device on the edge of a network such as a SAN is configured to replace the original source address of traffic entering the network with a known identifier or address, which is used to signify that entry point as the traffic source to the other nodes of the network. Nodes of the network recognize the new source address as a valid source address. The network device also maintains state (e.g., association of original source address with new source address/identifier) so as to translate addresses to enable reply traffic to be sent back to the original sender.

摘要： Network data storage systems and methods allow computers reading and writing data at a plurality of data centers separated by, potentially, large distances to replicate data between sites such that the data is protected from failures, including complete Site failures, while not allowing network latency to significantly impede the performance of read or write operations. Continued access to all data is provided even after a single failure of any component of the system or after any complete failure of all equipment located at any single geographic region or any failure that isolates access to any single geographic region. Write data is replicated synchronously from Active Sites, e.g., sites where servers are writing data to storage resources, to Protection Sites located sufficiently close to Active Sites such that network latency will not significantly impact performance, but sufficiently far apart such that a regional disaster is unlikely to affect both sites. Write data is then asynchronously copied to other sites, potentially including one or more Active sites, located at greater distances.
摘要翻译：网络数据存储系统和方法允许计算机在多个数据中心读取和写入数据，这些数据中心可能距离很远，以便在站点之间复制数据，从而保护数据免受故障，包括完整的站点故障，同时不允许网络延迟显着阻碍了读写操作的执行。即使在系统的任何组件发生单一故障之后或者位于任何单个地理区域的所有设备发生任何完全故障或者任何将访问隔离在任何单一地理区域的故障之后，仍可继续访问所有数据。写入数据从Active Sites（例如，服务器正在将数据写入存储资源的站点）同步复制到位于与Active Sites紧密相连的保护站点，以便网络延迟不会对性能造成重大影响，但区域灾难相当遥远不太可能影响两个网站。然后将写入数据异步复制到其他站点，可能包括位于更远距离的一个或多个活动站点。

摘要： Write order fidelity (WOF) is maintained for totally-active implementations wherein a plurality of access nodes at geographically separated sites can concurrently read and/or write data in a “totally active” fashion on a distributed data system. From the hosts' perspective at diverse geographic locations, a synchronous, cache-coherent view of data is provided. Data transfer is asynchronous. A time ordered data image is created and maintained so operations can be restarted after a partial system failure that causes loss of data not yet asynchronously transferred across the network, but that has been write-acknowledged to the originating host. Time ordered asynchronous data transfer is implemented as a pipeline of changes that reflect contributions from all nodes. WOF also improves network performance and lowers bandwidth consumption. Extensions can provide, in a totally-active context, features such as point-in-time snapshots, time firewalls, on-demand backend storage allocation, synchronous/asynchronous distribution of data, and continuous data protection.

摘要： Systems and methods for optimizing storage network functionality. The methods and systems of the present invention are particularly useful for optimizing storage network performance for cases in which some components of the network may be separated by significant distances and/or which include communication links with relatively limited bandwidth. In certain aspects, the present invention provides methods and systems for implementing access to and management of geographically distributed storage resources through multiple peer-to-peer storage network array management functions (AMFs) that may also be geographically distributed. The methods and systems of the present invention, in certain aspects, provide geographically aware cache sharing, cache replication, cache coherence, traffic routing, redundancy group structure, source and destination selection, pre-fetching of data, message gathering and other useful features.
