摘要： Support for virtualization in a storage area networks may be provided using a variety of techniques. In one embodiment of the present invention, exchange level load balancing may be provided by determining if input/outputs (IOs) received by a device are new. If a particular IO is new, the IO may be assigned to a particular data path processor and a context may be created corresponding to the IO and to the processor. Then, when an event corresponding to the IO is received, the event may be forwarded to the processor assigned to the IO.

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.
摘要翻译：在一个实施例中，提供了一种解决方案，其中锁管理器在多核或多处理器环境中在多个核心或处理器之间保持移动。通过将锁定管理器从处理器“跳转”到处理器，可以防止任何处理器的瓶颈。移动频率可以基于例如计数由锁定管理器处理的输入/输出的数量的计数器，并且一旦满足确定的阈值，则将锁定管理器移动到不同的处理器。在本发明的另一个实施例中，处理器之间的移动频率可以基于计时锁管理器在处理器上操作的时间量的时间，并且一旦预定时间是到达。

摘要： In one embodiment, a method is provided comprising: receiving, at a virtualizer, a write command from an initiator in a storage area network, wherein the storage area network includes the initiator and a plurality of mirrored storages; sending, from the virtualizer, a write command to the plurality of mirrored storages; receiving, at the virtualizer, a transfer ready message from a first of the plurality of mirrored storages; sending a transfer ready message from the virtualizer to the initiator in response to the receiving of the transfer ready message from the first of the plurality of mirrored storages; receiving, at the virtualizer, a data message from the initiator; and sending, from the virtualizer, a data message to the plurality of mirrored storage once transfer ready messages have been received from each of the plurality of mirrored storages.
摘要翻译：在一个实施例中，提供了一种方法，包括：在虚拟器处从存储区域网络中的发起者接收写入命令，其中所述存储区域网络包括所述发起者和多个镜像存储器; 从所述虚拟器发送写入命令到所述多个镜像存储器; 在所述虚拟器处接收来自所述多个镜像存储器中的第一个的传送就绪消息; 响应于从所述多个镜像存储器中的第一个接收到所述传送就绪消息，将传送就绪消息从所述虚拟器发送到所述发起者; 在所述虚拟器处接收来自所述发起者的数据消息; 以及一旦从所述多个镜像存储器中的每一个接收到传输就绪消息，则从所述虚拟器向所述多个镜像存储器发送数据消息。

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.
摘要翻译：一种用于在云存储系统中有效存储现场和场外数据的系统和方法。数据读写请求由云数据存储系统接收。云存储系统至少有三个数据存储层。第一高速层，第二有效存储层和第三异地存储层。第一个高速层将数据存储在原始数据块中。第二高效存储层将数据块从第一层划分成数据片，并消除重复的数据片。第三层在非现场位置存储数据切片。
