摘要： A security module is configured to provide an owner the capability to differentiate between users. In particular, the security module is configured to generate an asymmetric read/write key pair for respectively decrypting/encrypting data for storage on a disk. The owner of the file may distribute the read key of the asymmetric key pair to a group of users that the owner has assigned read-permission for the encrypted data.

摘要： The replication of a group of data sets is coordinated into a single schedule based on the recovery point objective (RPO) of each data set. The resulting generated schedule satisfies each data set's RPO requirements and minimizes bandwidth use. If necessary bandwidth exceeds available bandwidth, the resulting generated schedule attempts to best satisfy each data set's RPO requirements given the available bandwidth.

摘要： Apparatus and method for extending a standard-based remote file access protocol and maintaining compatibility with the standard protocol stack. Network file system (NFS) remote procedure calls (RPCs) that are submitted by an NFS client application are intercepted in a manner that is transparent to the client operating system. The intercepted NFS-RPCs are sent to a file interface card. The file interface card includes a processor that executes code that implements the standard NFS-RPC protocol, along with extensions to the standard NFS-RPC protocol. Non-NFS RPCs are sent to a conventional network interface card for processing.

摘要： Method and system for moving an object from a source partition server to a target partition server in a distributed file system having multiple partition servers. Each object has at least one associated and linked parent object, and each partition server owns a subset of objects of the file system. The object migration is accomplished by creating a copy in a target partition server of a selected object from a source partition server. At the source partition server, a forwarding link is created that references the copy in the target partition server. The copy is linked to the parent object of the selected object, and requests for access to the selected object are responded to with the forwarding link.

摘要： An embodiment of a method of controlling access to a computing resource within a shared computing environment begins with a first step of measuring performance parameters for workloads accessing the computing resource to determine a performance parameter vector for the workloads. The method continues with a second step of estimating a controller function for the computing resource by analysis of recent performance parameters and recent throughputs. The controller function comprises a mathematical operation which takes an input and provides an output. In a third step, the method compares the performance parameter vector to a reference performance parameter vector to determine an error parameter. In a fourth step, the method applies the controller function to the error parameter to determine a target throughput for each of the workloads. The method concludes with a fifth step of adjusting access to the computing resource for each work load having a throughput limit different from about the target throughput by reducing or increasing the throughput limit for the workload to about the target throughput.

摘要： According to one embodiment, a method comprises scheduling, by a weighted proportional-share scheduler, access of competing flows to a computing service in accordance with respective weights assigned to the competing flows. The method further comprises autonomously determining, by a controller, based at least in part on received performance measurement for the flows, values of the respective weights assigned to the competing flows for achieving respective performance goals desired for the competing flows. When determined by the controller that the values of the respective weights assigned to the competing flows should be changed for achieving the performance goals, the controller communicates the changed values of the respective weights to the weighted proportional-share scheduler.

摘要： A transactional shared memory system has a plurality of discrete application nodes; a plurality of discrete memory nodes; a network interconnecting the application nodes and the memory nodes, and a controller for directing transactions in a distributed system utilizing the shared memory. The memory nodes collectively provide an address space of shared memory that is provided to the application nodes via the network. The controller has instructions to transfer a batched transaction instruction set from an application node to at least one memory node. This instruction set includes one or more write, compare and read instruction subsets, and/or combinations thereof. At least one subset has a valid non null memory node identifier and memory address range. The memory node identifier may be indicated by the memory address range. The controller controls the memory node responsive to receipt of the batched transaction instruction set, to safeguard the associated memory address range during execution of the transaction instruction set. The batched transaction instruction set is collectively executed atomically. A notification instruction set may also be used to establish a notification, triggered upon a subsequent write event upon at least a portion of a specified address range.

摘要： Method and system for performing a namespace operation in a distributed file system. The file system is disposed on a plurality of partition servers, and each partition server controls access to a subset of hierarchically-related, shared storage objects. Each namespace operation involves a namespace object and a target object that are part of the shared storage objects. Namespace operations received at each partition server are serialized. In response to an unlink namespace operation, a reference in the namespace object to the target object is removed, and after removal the target object is modified in accordance with the unlink operation. In response to a link operation, the target object is modified consistent with the link operation. After modification of the target object, a reference to the target object is inserted in the namespace object.
