  • Patent number: 7546354
    Abstract: The present invention provides a scalable, highly available distributed network data storage system that efficiently and reliably provides network clients and application servers with access to large data stores, such as NAS units, and manages client and server requests for data from the data stores, thereby comprising a distributed storage manager. A storage manager constructed in accordance with the invention can receive and process network requests for data at a large, aggregated network data store, such as a collection of NAS units, and can manage data traffic between the network clients and NAS units.

  • Patent number: 6801949
    Abstract: 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.
