摘要： Embodiments of the invention relate to block layout and block allocation in a file system to support transparency of application processing. At least one copy of an application is replicated in a write affinity region of a secondary server, and at least one copy of the application is replicated in a wide striping region across a cluster file system. When the application is subject to failure, application processing is transferred from the failure location to the write affinity copy. At the same time, the failed application is rebuilt using the wide striping replication of the application. Once the application is rebuilt, processing may return to the failed location employing the rebuilt application.

摘要： Embodiments of the invention are directed to streaming virtual machine boot services over a network. An aspect of the invention includes booting a first virtual machine and recording data and metadata from a virtual machine boot image into a virtual machine boot file. The data and metadata are accessed in the process of booting the first virtual machine. The virtual machine boot image has setup information of the virtual machine type of the first virtual machine. The virtual machine boot file is configured for the virtual machine type of the first virtual machine. A descriptor is added to metadata of the virtual machine boot image, which references a location of the virtual machine boot file for the virtual machine type of the first virtual machine. When subsequently booting a second virtual machine of the same type of virtual machine as the first virtual machine, data are streamed from the virtual machine boot file to a virtual machine monitor of a second virtual machine without the need to stream data from the virtual machine boot image.

摘要： A method, system, and article are provided to enable a Hyperswap operation in a clustered computer system. Each node in the system is configured with flash memory, with a hierarchical list of boot volumes therein. Following a Hyperswap operation, the current boot volume is communicated to each node in the cluster and each node joining the cluster. All previously inactive nodes that were booted from the improper boot volume are re-booted from the correct and the flash memory is amended to reflect the correct boot volume.

摘要： Embodiments of the present invention provide an approach for migrating virtual machines across network (e.g., WAN) separated data centers (e.g., storage clouds). Specifically, under embodiments of the present invention, a first storage system associated with a first data center is synchronized with a second storage system associated with a second data center via a storage system link. Then, a minimal state of a virtual machine is migrated from a first computer in the first data center to a second computer in the second data center via a WAN link. Using the minimal state, the virtual machine is stored in the second computer. Thereafter, the storage system link is terminated. In addition, as updated pages are received in memory of the first computer, they are migrated to the second computer via the WAN link. Once this migration is complete, the WAN link can be terminated. Therefore, embodiments of the present invention provide at least two forms of synchronization: computational synchronization and storage synchronization.

摘要： A method and system for data traffic management in a storage area network subsystem connected to multiple hosts via plural ports through a connection network is provided. Traffic management involves, for each port, determining input/output (IO) traffic utilization load of the port based on workloads from one or more hosts assigned to that port; and detecting if a port is in utilization overload. Then, upon detecting a port utilization overload, port traffic is managed by adjusting traffic utilization of the overloaded port and one or more other ports in the storage subsystem, to reduce traffic utilization of the overloaded port.

摘要： A method and system for automatically identifying an optimal set of attributes of entities included in a networked system. Entity types are ranked based on information gain. A first classification accuracy relative to a first entity type is determined. The first entity type is the top-ranked entity type or a first aggregate entity type. A second entity type is selected base on the ranking. A database join of a first set of attributes associated with the first entity type and a second set of attributes associated with the second entity type is performed. A second classification accuracy relative to a second aggregate entity type generated by the join is determined. In response to determining that the second classification accuracy is not greater than the first classification accuracy, an optimal set of attributes contributing to a problem in the networked system is identified as the first set of attributes.

摘要： Provided are a method, system, and article of manufacture for varying access parameters for processes to access memory addresses in response to detecting a condition related to a pattern of processes access to memory addresses. A monitored condition is detected during application execution. An instrumentation program is invoked to monitor processes accessing data at addresses in a memory device in response to detecting the monitored condition. Information is logged on processes and the addresses they access in the memory device in response to invoking the instrumentation program. The logged information on the processes and the addresses they access is forwarded to an application analysis system in response to detecting a monitored condition during application execution.

摘要： In a storage area network, the storage pool is the principal component that determines the storage quality of service in the network. The proposed system's goal is to balance the utilizations of the storage pools using a suitable metric (e.g., standard deviation). The utilization of a storage pool is determined by the same components that are part of the composition of the storage pool: the disks and the storage systems. This system then gathers performance information about all the storage pools and applies the described method to determine a sequence of resource-reallocations so that a well-balanced utilization of pools is achieved.
