An information processing system comprises one or more processing platforms and implements a centralized storage provisioning and management system and a plurality of service provider storage systems coupled to the centralized storage provisioning and management system. The centralized storage provisioning and management system is configured to control provisioning and management of the service provider storage systems utilizing information collected from the service provider storage systems. The service provider storage systems may comprise respective service provider data centers, and the centralized storage provisioning and management system may comprise an additional data center separate from the service provider data centers. The centralized storage provisioning and management system may comprise a centralized control path implemented apart from the service provider storage systems. The centralized control path is configured to interact with a plurality of localized control paths implemented in respective ones of the service provider storage systems.

A checkpointing method in a network device fault tolerant system using virtual machines. In one embodiment, the network device has an input port, an output port, an active virtual machine and a standby virtual machine, a network application on the active virtual machine which manipulates data present on the input port and transmits the manipulated data from the output port; a checkpoint engine on the active virtual machine; and an interface agent, on the active virtual machine, having callable functions to move data from the input port to the output port. The method includes the steps of determining, by the checkpoint engine, that a checkpoint is required; requesting by the checkpoint engine that the interface agent quiescent itself; returning, by the interface agent to the network application, an indicator that no packets are available regardless of whether or not packets are arriving at the input port.

An information processing system comprises a centralized database and at least one processing device implementing a selection algorithm for automated provisioning and management of a plurality of storage arrays based on information collected from the storage arrays and stored in the centralized database. The information stored in the centralized database may comprise at least one of storage utilization, performance, network bandwidth and end of service for each of the storage arrays. The selection algorithm is configured to determine optimal placement of data across the storage arrays based on the information stored in the centralized database. For example, the selection algorithm may be configured to determine one or more locations within the plurality of storage arrays to allocate as new storage responsive to a provisioning request.
