摘要： Method and apparatus for data migration are described herein. In one embodiment, in response to data received from an application to be written to a first storage volume, the data is written to the first storage volume and a second storage volume substantially concurrently. When the first and second storage volumes are synchronized, a switchover is performed from the first storage volume to the second storage volume, such that subsequent data received from the application is written to the second storage volume, where writing the data to the first and second storage volumes and the switchover are performed without knowledge of the application. Other methods and apparatuses are also described.

摘要： A system, method and computer program to detect and recover from a communications failure in a computer network. The computer network has several nodes which include processor-based systems, input/output controllers and network controllers. Each node has a cluster adapter connected to multiple port switches through communications links. Data is transmitted through among the nodes through the communications links in the form of packets. A fabric manager module will monitor the network and detect a link failure. Upon the detection of a link failure between two switches a spanning tree partitioning module will partition the network into two trees at the point of the link failure. Thereafter, a link and switch identification module will identify a link between the two trees that can replace the failed link and has the least impact on the network. A routing table calculation algorithm module will calculate a new routing and distance table based on the identified link. The fabric manager module will then download the routing and distance table to only those switches effected by the new link selected to replace the failed link. This identification and recovery from communications link failures may be done with little overhead and without taking the network offline.

摘要： This invention is a software application utilizing distributed storage systems to provide backup, archive and disaster recovery (BCADR) functionality across multiple clouds. The multi-cloud aware BCADR application and distributed storage systems are utilized together to prevent data lost and to provide high availability in disastrous incidents. Data deduplication reduces the storage required to store many backups. Reference counting is utilized to assist in garbage collection of staled data chunks after removal of staled backups.

摘要： A cluster includes a fabric, a host coupled to the fabric, an I/O enclosure coupled to the fabric, and a subnet manager. The subnet manager performs a topology discovery of the cluster and detects ports associated with the fabric. The subnet manager computes a minimal spanning tree for the cluster, which connects every port to every other port through a single path. The subnet manager assigns a single base LID to each port and programs the assigned LIDs into forwarding tables in the fabric. Additional LIDs are reserved for each port while the single base LID is assigned to each port such that the fabric is functional and connected when the subnet manager is performing a path analysis of the cluster.
