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 relate to block layout and block allocation in a file system to support write transactions. Regions in a cluster file system are defined to support a block allocation, include both write affinity and wide striping region. An allocation map is maintained to define and support the block allocation regions. For each write transaction, a copy of data is written to both regions, and in the event there is a shortage of blocks in one of the regions, at least one block in the other region is dynamically converted to support the write transaction.

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： 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.

摘要： Embodiments of the invention relate to synchronization of data in a shared pool of configurable computer resources. An image of the filesystem changes, including data and metadata, is captured in the form of a consistency point. Sequential consistency points are created, with changes to data and metadata in the filesystem between sequential consistency captured and placed in a queue for communication to a target filesystem at a target site. The changes are communicated as a filesystem operation, with the communication limited to the changes captured and reflected in the consistency point.

摘要： Techniques are disclosed for peer-to-peer data transfers where a source device receives a request to read data words from a target device. The source device creates a first and second read command for reading a first portion and a second portion of a plurality of data words from the target device, respectively. The source device transmits the first read command to the target device, and, before a first read operation associated with the first read command is complete, transmits the second read command to the target device. The first and second portions of the plurality of data words are stored in a first and second portion a buffer memory, respectively. Advantageously, an arbitrary number of multiple read operations may be in progress at a given time without using multiple peer-to-peer memory buffers. Performance for large data block transfers is improved without consuming peer-to-peer memory buffers needed by other peer GPUs.

摘要： Embodiments of the invention relate to optimizing a file system for different types of applications in a compute cluster using dynamic block size granularity. An exemplary embodiment includes reserving a predetermined number of storage allocation regions for each node in a cluster, wherein each storage allocation region comprises a set of contiguous data blocks on a single storage disk of locally attached storage; using a contiguous set of data blocks on a single storage disk of locally attached storage as a file system's block allocation granularity for striping data to be stored in the file system for a compute operation in the cluster; and using a single data block of a shared storage subsystem as the file system's block allocation granularity for striping data to be stored in the file system for a data access operation in the cluster.
