Abstract: A data storage system has at least two universal nodes each having CPU resources, memory resources, network interface resources, and a storage virtualizer. A system controller communicates with all of the nodes. Each storage virtualizer in each universal node is allocated by the system controller a number of storage provider resources that it manages. The system controller maintains a map for dependency of virtual appliances to storage providers, and the storage virtualizer provides storage to its dependent virtual appliances either locally or through a network protocol (N_IOC, S_IOC) to another universal node. The storage virtualizer manages storage providers and is tolerant to fault conditions. The storage virtualizer can migrate from any one universal node to any other universal node.
