摘要： A computer-implemented method for managing data snapshots among source and target storage volumes in a dual-controller environment. A configuration space that maps the source and target storage volumes to first and second logical drives respectively is established. The configuration space is then divided into first and second portions, wherein a first storage controller controls the first portion and a second storage controller controls the second portion. A snapshot relationship is established between the source and target storage volumes such that portions of data on the source storage volume are logically mirrored on the target storage volume. The identical snapshot relationship is stored in both the first and second storage controllers. In response to a request to perform an operation that results in a modification of the snapshot relationship, the operation is performed. and then a modified snapshot relationship is transferred to the first and second controllers. The modified snapshot relationship reflects the operation, thereby synchronizing the snapshot relationship data in the first and second controllers.

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： Embodiments are directed towards managing a display of search results by employing a query-classification for a search query to selectively display trust search results that are displayed distinct from non-trust search results. A search query is classified into a query-class. A search is then performed over non-trust sources, and selectively over trust data sources to obtain non-trust and trust search results, respectively. The trust search results are rank ordered based on various categories of search criteria, including, for example, explicit and implicit relationships. Based on the query-class, a different number of trust search results may be displayed. Further, a position for which the trust search results may be displayed may be based on the query-class. Moreover, the non-trust search results displayed distinct or separate from the trust search results to readily distinguish a type of source of the search results.

摘要： A mechanism to permit consolidation of storage subsystem volumes into larger, more easily managed volumes and an operating system device driver which includes a trap mechanism for intercepting calls from a host into logical unit devices that were previously consolidated into a single physical volume. A map converts such calls to a logical unit device into a corresponding offset in the single physical volume. A driver accesses the single physical volume with corresponding offsets to transfer data associated with a particular logical unit device. So, logical unit devices can be consolidated and reconsolidated to single physical volumes and other physical volumes without requiring changes to the operating system or its application software and without requiring application or host downtime.

摘要： A system for serving advertisements in a networked environment includes a web feed ad server operable to receive web feed information, identify concept terms in the web feed information, match advertisements to the concept terms, and communicate the advertisement to a terminal. Concept terms are identified by comparing terms in the web feed to information in an encyclopedia database, a product listing database, and/or a bidded keyword database. Rewrites associated with the concept terms are generated by a sponsored search ad system. The concept terms and rewrites are placed in a document and communicated to a context matching ad system operable to match an advertisement to the content of the document.

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.
