Abstract: This invention is a system and method for network management for data transfer which may include replication in a data storage environment. It is useful for managing network allocation of resources (e.g., bandwidth) needed for such replication of data in a data storage environment. The invention is particularly useful with a network using an internet protocol environment and allows for management of bandwidth needed for a replication process. The method includes the steps of requesting from a server for services on an internet network, a bandwidth for data transfer over the internet. The data is transferred in response to a bandwidth allocation from the server based on the request. The network traffic characteristics (e.g. packet loss or latency, and session time outs) are monitored during the data transfer. If the process lags behind more bandwidth is allocated.

Abstract: This invention is a system and method for managing replication of data in a data storage environment by grouping logical devices. The system is enabled for configuring, monitoring, and controlling replication processes in accordance with a replication policy that is particularly useful when combined with grouping of logical devices used in replication. The invention is useful for replicating essentially an entire copy of a production-level database such that the copy may be used essentially as the production-level database itself.

Abstract: According to one embodiment of the present invention, a network adapter is provided that may be used to interface to a network environment a first data storage system. The adapter includes a switching system that may be coupled to data exchanging devices in the network environment, and port circuitry that may be used to facilitate establishment of a link between the first data storage system and a second, remote data storage system in the network environment. The link, when established, may facilitate the establishment of a target device in the second data storage device as a mirror device that may comprise a mirror of data residing in a source device in the first network data storage system.
