A method, article of manufacture, and apparatus for efficiently processing information. In some embodiments, this includes selecting a service to add to a storage array, determining a virtual appliance associated with the service, and instantiating the virtual appliance. In some embodiments, instantiating the virtual appliance includes instantiating an image of the virtual appliance.

Instantiating virtual appliances of a storage array

A method, article of manufacture, and apparatus for efficiently processing information. In some embodiments, this includes determining a physical appliance to virtualize, creating a virtual appliance based on the physical appliance, and storing the virtual appliance in a storage array. In some embodiments, creating the virtual appliance includes creating the virtual appliance from a template.

Virtual appliance deployment

Needless migration of duplicate file data is avoided by recording in a database a record of migration of a first instance of a replicated file from a source file server to a target file server. When migrating a subsequent instance of a replicated file to the target file server, the database is searched for a record of replication of a first instance of the replicated file to the target file server. If such a record is found, the subsequent instance is replicated by sending from the source file server to the target file server attributes of the subsequent instance of the replicated file and an identification of the previously migrated data of the replicated file without re-transmission of the previously migrated data of the replicated file.

A method, article of manufacture, and apparatus for efficiently processing information. In some embodiments, this includes selecting a service to terminate, determining a virtual appliance associated with the service, and decommissioning the virtual appliance. In some embodiments, the virtual appliance may be deleted from the storage array.

Decommissioning virtual appliances

A method, article of manufacture, and apparatus for efficiently processing information. In some embodiments, this includes determining a physical appliance to virtualize, creating a virtual appliance based on the physical appliance,and storing the virtual appliance in a storage array. In some emdodiments, creating the virtual appliance includes creating the virtual appliance from a template.

A method, system, and program product for implementing consistent snapshots in a replication environment, the replication environment having a production site having a splitter, and a storage media the method comprising, selecting a set of media from the storage medium, creating a consistency group of the selected set of storage media, creating a journal at the production site, splitting I/O to the consistency group, and recording the split I/O in the journal.

Instantiating virtual appliances

The present invention provides a system and method for abstracting multiple network attached storage ('NAS') locations, providing a single global namespace and a single mount point that is protocol and location-independent. As a result, rather than identifying each NAS and file server by location, access is provided through a single transparent mechanism. In order to maintain transparency, the present invention provides a way to reconcile the different naming practices for different file server protocols.

Multi-protocol global namespace mechanism for network attached storage

A distributed gateway for controlling computer network data traffic dynamically reconfigures traffic assignments among multiple gateway machines for increased network availability. If one of the distributed gateway machines becomes unavailable, traffic assignments are moved among the multiple machines such that network availability is substantially unchanged. The machines of the distributed gateway form a cluster and communicate with each other using a Group Membership protocol word such that automatic, dynamic traffic assignment reconfiguration occurs in response to machines being added and deleted from the cluster, with no loss in functionality for the gateway overall, in a process that is transparent to network users, thereby providing a distributed gateway functionality that is scalable. Operation of the distributed gateway remains consistent as machines are added and deleted from the cluster. A scalable, distributed, highly available, load balancing network gateway is thereby provided, having multiple machines that function as a front server layer between the network and a back-end server layer having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines comprise a server cluster that performs fail-over and dynamic load balancing for both server layers.

Distributed traffic controller for network data

A scalable, distributed, highly available, load balancing server system having multiple machines is provided that functions as a front server layer between a network (such as the Internet) and a back-end server layer having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines comprise a server cluster that performs fail-over and dynamic load balancing for both server layers. The operation of the servers on both layers is monitored, and when a server failure at either layer is detected, the system automatically shifts network traffic from the failed machine to one or more operational machines, reconfiguring front-layer servers as needed without interrupting operation of the server system. The server system automatically accommodates additional machines in the server cluster, without service interruption. The system operates with a dynamic reconfiguration protocol that permits reassignment of network addresses to the front layer machines. The front layer machines perform their operations without breaking network communications between clients and servers, and without rebooting of computers.
