摘要： Systems and methods in accordance with various disclosed embodiments can manage a mirrored virtual target to synchronize the members of the virtual target and/or to verify that the members of the virtual target are synchronized. In one embodiment, a mirrored virtual target is synchronized by first provisioning at least one first internal virtual logical unit (IVLU) corresponding to at least one destination target of the mirrored target and a second IVLU corresponding to a source target of the mirrored target. A write command is first issued, via one or more internal virtual logical units, to each of the destination target members of the mirrored target. When each destination target is available to receive data, as evidenced by a returned transfer ready signal, a read command is provided to the source target via the second internal virtual logical unit. In this manner, a data path between the source and destination targets is established prior to reading data from the source target. Accordingly, the data can be read from the source target, converted to write data, and routed to the destination targets at line speed without buffering of the data. A similar process is provided to verify that the members of a mirrored target are synchronized. In one embodiment, a system and method is provided to manage incoming commands for the mirrored target while synchronizing or verifying synchronization of the mirrored target. Incoming commands can be queued as they are received and provided to the mirrored target when pending synchronization or verification commands are completed.

摘要： Systems and methods in accordance with various embodiments can detect and alleviate potential or actual deadlock of a storage switch or storage area network when attempting to write data to a mirrored virtual target. In accordance with one embodiment, a timer is started when a storage switch routes a write command to the physical targets corresponding to a virtual target of the write command. If each physical target does not return a transfer ready resource within a predetermined timeout period, the switch determines that a potential or actual deadlock has occurred. An abort command is sent to each of the physical devices. The abort command can clear the command from the targets and also free any allocated transfer ready resources. After receiving an acceptance response from each physical target, the state of the write command at the switch can be cleared. The write command can then be re-issued to the physical devices. In one embodiment, a queue depth for the virtual target can be lowered after failing to receive transfer ready resources from each target. By decreasing the queue depth, the maximum number of commands the switch will process for a virtual target is decreased to decrease the probability of future deadlock. In one embodiment, the queue depth is increased after no deadlock is detected for a period of time.
摘要翻译：根据各种实施例的系统和方法可以在尝试将数据写入到镜像的虚拟目标时，检测和减轻存储交换机或存储区域网络的潜在或实际的死锁。根据一个实施例，当存储交换机将写入命令路由到与写入命令的虚拟目标相对应的物理目标时，启动定时器。如果每个物理目标在预定的超时期间内不返回传送就绪资源，则交换机确定发生了潜在或实际的死锁。将一个中止命令发送到每个物理设备。 abort命令可以清除目标中的命令，并释放任何分配的传输就绪资源。在接收到每个物理目标的接受响应后，可以清除交换机上的写命令的状态。然后可以将write命令重新发送到物理设备。在一个实施例中，在不能从每个目标接收传送就绪资源之后，可以降低虚拟目标的队列深度。通过减少队列深度，减少交换机将为虚拟目标处理的命令的最大数量，以减少未来死锁的概率。在一个实施例中，在一段时间内没有检测到死锁之后，队列深度增加。

摘要： A storage switch is disclosed that facilitates mirroring of data. For example, a target is mirrored when an identical (or almost identical) copy of the data is stored in two or more separate physical data stores. Because the various data stores may not be homogenous, they may provide for different burst sizes. To accommodate the different burst sizes, the switch provides different sequence counts for data packets sent to the different data stores that store the mirrored data.

摘要： Systems and methods in accordance with various embodiments can manage transfer ready resources of one or more physical targets to avoid deadlock of a storage switch or storage area network when attempting to write data to a mirrored virtual target. When writing data to a mirrored virtual target, a storage switch simultaneously or synchronously routes data from an initiator to multiple physical locations, such as multiple physical targets. A switch or network can become deadlocked while waiting to receive a transfer ready resource from each of the physical targets involved in the operation. In accordance with an embodiment, a storage switch determines the availability of a transfer ready resource from a physical target prior to issuing a write command to the target. In this manner, the switch can ensure that the target will be available to issue a transfer ready signal when a write command is issued, thus alleviating potential deadlock situations. In accordance with one embodiment, a resource table can be used to store an indication of the availability of transfer ready resources from one or more targets. The resource table can be updated as transfer ready resources are allocated to incoming commands. In one embodiment, a circular first in/first out buffer can be used to queue information relating to write commands for mirrored virtual targets.

摘要： In accordance with an embodiment of the present invention, a method for inserting secondary content into a media stream includes dividing the media stream having a plurality of frames into a plurality of shots at a processor. The method further includes grouping consecutive shots from the plurality of shots into a plurality of scenes. A first list of insertion points is generated for introducing the secondary content. The insertion points of the first list are boundaries between consecutive scenes in the plurality of scenes. An average insertion point saliency of the media stream is generated at the insertion points in the first list. A second list of insertion points is then generated. The insertion points in the second list are arranged to maximize a function of the average insertion point saliency and a distance between each insertion point in the second list with other insertion points in the second list.
