    摘要： A system, program product, and computer implemented method for data replication, comprising enabling a virtual service layer to consume a storage medium of a site and map the storage medium of the site as one or more virtual storage volumes, enabling the virtual service layer to present the one or more virtual storage volumes for consumption by a host, enabling a splitter of the site to intercept I/O written to the one or more virtual storage volumes, splitting intercepted I/O to a journal based replication appliance, and enabling the journal based replication appliance to create a continuous data protection image of the data written to one or more virtual storage volumes.

    摘要： A computer implemented method, system, and computer program product for recovering from a crash of a system being replicated, the method comprising determining the amount of recovery time due to the crash of each of a set of hypervisors; wherein each of the hypervisors runs one or more data replication elements selected from the group consisting of a splitter and a replication appliance; wherein each of the splitters and replication appliances replicates one or more volumes, creating an assignment of the one or more volumes to the set of replication appliances and creating an assignment of one or more replication appliances to a set of hypervisors to minimize the amount of recovery time.

    摘要： In one aspect, a method to upgrade software on nodes in a clustered environment, includes terminating processes on a first node before upgrading the software on the first node, upgrading the software to a first version from a second version on the first node, running the processes on the first node after upgrading the software on the first node to the first version, determining whether a second node is about to upgrade to the first version of software, allowing transfer of site control from the second node to the first node, if the second node is about to upgrade to the first version of software and upgrading the software on the second node to the first version of software after the transferring of site control from the second node to the first node.
