Abstract: 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.

Abstract: 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.

Abstract: In a cluster of computing nodes having shared access to one or more volumes of data storage using a parallel file system, a method for managing the data storage includes initiating a data management application in the cluster using a data management application programming interface (DMAPI) of the parallel file system. When a request submitted to the parallel file system is received on one of the nodes to perform an operation on a file in one of the volumes of data storage, a data management access right is obtained from the DMAPI responsive to the request The operation is performed on the file using the access right.

Abstract: In a cluster (20) of computing nodes (22) having shared access to one or mor e volumes of data storage (24) using a parallel file system (28), a method for managing the data storage includes initiating a session of a data management application (32) on a first one of the nodes (40), while running a user application (30) on a second one of the nodes (42). A request is submitted t o the parallel file system by the user application on the second node to perfo rm a file operation on a file in one of the volumes of data storage. A data management event message is sent from the second node to the first node responsive to the request, for processing by the data management application on the first node.
