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 relate to a storage switch including task processing synchronization. In embodiments of the present invention, the packet processing units may generate and store Task Index and Generation Count information that prevents the processing of expired commands or responses. Additionally or alternatively, embodiments of the present invention may further employ timeout sequences to prevent previous instances of a stale task resource from disrupting the current use of the task resource.

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 can provide mirrored virtual targets and online synchronization and verification of the targets while avoiding deadlock, inconsistencies between members of the target, and false verification failures. A lock within the storage switch can limit the number of outstanding commands for a physical target to one during synchronization and verification operations. In one embodiment, a lock can be implemented as one or more resource tables maintaining an indication of the number of transfer ready signals available from physical targets. During typical write operations, deadlock can be avoided by determining whether each physical target for the mirrored operation can issue a transfer ready signal prior to issuing a command to the physical target. When a synchronization or verification operation begins, the maximum available number of transfer ready signals for each target can be decremented to one in order to limit the total number of outstanding commands for each target to one.

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 switch including a processor and method for monitoring bandwidth in the storage switch. The switch includes at least one physical port coupling at least one target and at least one initiator via the physical port. The monitoring method may include the steps of determining whether congestion occurs on the physical port and assigning a weight to bandwidth usage between the initiator and the target based on a minimum and maximum bandwidth settings for each target. The switch may further include a step of controlling bandwidth usage by each of said at least two targets based on minimum and maximum bandwidth settings for each of the targets.
