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 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： Methods and apparatus are provided for alleviating deadlock and controlling congestion in a network such as a fibre channel network. Techniques are provided for detecting stalled frames at a fibre channel switch. Reserve credits are released when stalled frames are detected. In some instances, reserve credits are released after a predetermined period of time. Reserve credits allow transmission to effectively reduce deadlock and congestion. Reserve credits are particularly effective in reducing deadlock resulting from transient loops in a fibre channel network.

摘要： Methods and apparatus for performing Storage Media Encryption (SME) are disclosed. In one embodiment, an apparatus includes a memory and a plurality of processors. The apparatus receives a write command from a network device. The apparatus sends a transfer ready to the network device in response to the write command. The apparatus receives data from the network device. The apparatus composes a status and sends the status the network device. The status is sent to the network device after the data has been received from the network device and prior to both compressing and encrypting the data. The apparatus compresses the data to generate compressed data. One of the plurality of processors encrypts the compressed data to generate modified data. The apparatus then sends the modified data to a target indicated by the write command.

摘要： Fine granularity exchange level load balancing may be performed in a device in a storage area network in order to ensure that processors in a multi-core environment are not overloaded. This may be accomplished by assigning input/outputs relating to a particular exchange to a specific processor, and maintaining that association so that subsequent related input/outputs are handled by the same processor. In this process, the system may first determine if a received IO is new. If so, then it may assign the IO to a particular data path processor and create a context corresponding to the IO and the processor, as well as to the type of the non-command frame. Subsequently, an event may be received corresponding to the IO, which may then be forwarded to the processor assigned to the IO.
摘要翻译：可以在存储区域网络中的设备中执行精细粒度交换级别负载平衡，以确保多核环境中的处理器不会过载。这可以通过将与特定交换机相关的输入/输出分配给特定处理器来实现，并且保持该关联，使得随后的相关输入/输出由相同的处理器处理。在该过程中，系统可以首先确定接收的IO是否是新的。如果是这样，那么它可以将IO分配给特定的数据路径处理器并创建与IO和处理器相对应的上下文以及非命令帧的类型。随后，可以接收对应于IO的事件，然后可将该事件转发到分配给IO的处理器。
