摘要： Methods, systems, and computer program products are provided for performing a secure delete operation in a wide area network (WAN) including a cache site and a home site. A method includes identifying a file for deletion at the cache site, determining whether the file has a copy stored at the home site, detecting a location of the copy at the home site prior to a disconnection event of the cache site from the home site, deleting the file from the cache site during the disconnection event, and performing a secure deletion of the copy at the home site immediately after a reconnection event of the cache site to the home site.

摘要： Embodiments of the invention relate to dynamic application migration in a shared pool of configurable computer resources with disaster recovery support. Data from an application is replicated from local data storage to remote data storage. A consistency point of the data is created in both the local data storage and the remote data storage. The application may be migrated to a second data site with separate local data storage. The migration may be planned or unplanned. Based upon the created consistency point, a consistent set of application data may be requested to support a read operation from the migrated application.

摘要： Scalable caching of remote file data in cluster file systems is provided. One implementation involves maintaining a cache in a local cluster file system and caching local file data in the cache by fetching file data on demand from the remote cluster file system into the local cached file system over the network. The local file data and metadata corresponds to the remote file data and metadata in the remote cluster file system. Updates made to the local file data and metadata are pushed back to the remote cluster file system asynchronously.

摘要： The increasing number of Internet users and innovative new services such as e-commerce are placing new demands on Web servers. It is becoming essential for Web servers to provide performance isolation, have fast recovery times, and provide continuous service during overload at least to preferred customers. The invention describes a kernel-based architecture for content-aware service differentiation that protects Web servers against overload by controlling the amount and rate of work entering the system. We have invented a mechanism that provides admission control and service differentiation based on connection and application level information. The application header-based connection control uses application-level information (such as URIs and cookies for HTTP) to define different service differentiation actions. The present invention provides the kernel mechanisms that are more efficient and scalable than application level controls implemented in current Web servers.

摘要： A method and system for dynamically allocating cache space in a storage system among multiple workload classes each having a unique set of quality-of-service (QoS) requirements. The invention dynamically adapts the space allocated to each class depending upon the observed response time for each class and the observed temporal locality in each class. The dynamic allocation is achieved by maintaining a history of recently evicted pages for each class, determining a future cache size for the class based on the history and the QoS requirements where the future cache size might be different than a current cache size for the class, determining whether the QoS requirements for the class are being met, and adjusting the future cache size to maximize the number of classes in which the QoS requirements are met. The future cache sizes are increased for the classes whose QoS requirements are not met while they are decreased for those whose QoS requirements are met.
摘要翻译：一种用于在多个工作负载类别中动态地分配存储系统中的高速缓存空间的方法和系统，每个工作负载类别具有唯一的服务质量（QoS）要求。本发明根据每个类的观察到的响应时间和每个类中观察到的时间局部性动态地适应分配给每个类的空间。通过维护每个类别的最近被逐出的页面的历史来实现动态分配，基于历史和QoS要求确定将来的高速缓存大小，其中将来的高速缓存大小可能与该类的当前高速缓存大小不同，确定是否满足该类的QoS要求，以及调整未来的高速缓存大小以最大化满足QoS要求的类的数量。对于满足QoS要求的类，对于满足QoS要求的用户而言，对于不满足QoS要求的类，对于未来的高速缓存大小会有所增加。

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.
