    摘要: A system and method of managing data movement are provided in which a processing environment is established in a cluster of nodes. The nodes have common access to data residing in one or more data storage units. A data management application (DM) is initiated in the environment. One of the nodes of the cluster is assigned as a coordinating node for managing data movement. Thereafter, a worker thread is posted to one or more of the nodes in the cluster to perform one or more data movement tasks in response to the event. Preferably, a process session is established in the cluster. A session identifier and a data management access right are provided to one or more nodes to permit only the node or nodes having them to execute the worker thread posted to it.

    摘要: A system adapted to provide quality of service (QoS) for an iSCSI environment including one or more initiators and one or more targets. Each initiator includes an iSCSI initiator and a TCP layer. The iSCSI initiator includes a QoS shaper for shaping one or more iSCSI PDUs according to QoS policies. The TCP layer includes a QoS marker for marking the PDUs according to the QoS policies. The target includes a first and second QoS component. The first QoS component is in an iSCSI target and handles I/O resources. The first QoS component shapes read commands and write commands according to QoS policies. The second QoS component is in a TCP layer and handles network resources. iSCSI PDUs are shaped and marked according to QoS policies of iSCSI. The QoS policies used by the initiators and targets include policies for network resources and policies for I/O resources.

    摘要: An initiator node adapted to provide quality of service (QoS) for an Internet Small Computer System Interface (iSCSI) environment is provided. The initiator node including an iSCSI initiator comprising a QoS shaper, the QoS shaper for shaping one or more Protocol Data Units (PDUs) according to QoS policies and providing shaped PDUs, and a Transmission Control Protocol (TCP) layer for receiving the shaped PDUs from the iSCSI initiator and comprising a QoS marker for marking the shaped PDUs according to the QoS policies, wherein the PDUs are command PDUs and wherein the shaper shapes the command PDUs before the command PDUs receive command sequence numbers.
