摘要： A virtualization system provides virtualized servers at a branch network location. Virtualized servers are implemented using virtual machine applications within the virtualization system. Data storage for the virtualized servers, including storage of the virtual machine files, is consolidated at a data center network location. The virtual disks of the virtualized servers are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. The virtualization system accesses a storage block cache at the branch network location that includes storage blocks prefetched based on knowledge about the virtualized servers. The virtualization system can include a virtual LAN directing network traffic between the WAN, the virtualized servers, and branch location clients. The virtualized servers, virtual LAN, and virtual disk mapping can be configured remotely via a management application. The management application may use templates to create multiple instances of common branch location configurations.

摘要： Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. The virtual storage arrays overcomes bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client in the near future. Virtual storage arrays determine the association between requested storage blocks and corresponding high-level data structure entities to predict additional high-level data structure entities that are likely to be accessed. From this, the virtual storage array identifies the additional storage blocks for prefetching.
摘要翻译：虚拟存储阵列将通过广域网连接的数据中心的分支数据存储整合。虚拟存储阵列对存储客户端显示为本地数据存储; 然而，虚拟存储阵列实际上将数据存储在数据中心。虚拟存储阵列通过预测和预取存储块来克服广域网的带宽和延迟限制，然后将存储块缓存在分支位置。虚拟存储阵列利用对与存储块相关联的高级数据结构的语义和结构的理解，以预测存储客户端在不久的将来可能要求哪些存储块。虚拟存储阵列确定所请求的存储块和相应的高级数据结构实体之间的关联，以预测可能被访问的附加高级数据结构实体。从此，虚拟存储阵列识别用于预取的附加存储块。

摘要： In a network that conveys requests from clients to servers and responses from servers to clients, a network transaction accelerator for accelerating transactions involving data transfer between at least one client and at least one server over a network comprising a client-side engine, a server-side engine and a transaction predictor configured to predict, based on past transactions, which transactions are likely to occur in the future between the client and server. The transaction predictor might be in the server-side engine, the client-side engine, or both. The client-side engine receives indications of requests from the client, a transaction buffer for storing results of predicted transactions received from the server or the server-side engine ahead of receipt of a corresponding request, and a collator for collating the requests from the client with the stored results or received results, wherein a request and a response that are matched by the collator are identified and the matched response is provided to the client in response to the matched request. The server-side engine receives indications of transactions including requests and responses and conveys requests to the server in response to actual transactions or predicted transactions.
摘要翻译：在将来自客户端的请求传达到服务器的请求和从服务器到客户机的响应的网络中，提供一种网络事务加速器，用于加速涉及通过网络的至少一个客户端与至少一个服务器之间的数据传输的事务，包括客户端引擎，侧引擎和事务预测器，其被配置为基于过去的事务预测在将来在客户端和服务器之间可能发生哪些事务。事务预测器可能位于服务器端引擎，客户端引擎或两者中。客户侧引擎接收来自客户端的请求的指示，用于存储从服务器或服务器端引擎收到的对应请求之前收到的预测事务的结果的事务缓冲器，以及用于对来自客户机的请求进行整理的归类器存储结果或接收结果，其中识别由归类器匹配的请求和响应，并且响应于匹配的请求向客户端提供匹配的响应。服务器端引擎接收包括请求和响应在内的交易的指示，并且响应于实际交易或预测交易向服务器传送请求。
