Abstract: An improved architecture is provided which enables significant convergence of the components of a system to implement virtualization. The infrastructure is VM-aware, and permits scaled out converged storage provisioning to allow storage on a per-VM basis, while identifying I/O coming from each VM. The current approach can scale out from a few nodes to a large number of nodes. In addition, the inventive approach has ground-up integration with all types of storage, including solid-state drives. The architecture of the invention provides high availability against any type of failure, including disk or node failures. In addition, the invention provides high performance by making I/O access local, leveraging solid-state drives and employing a series of patent-pending performance optimizations.

Abstract: Methods, systems and computer program products for hibernating a computing cluster. An information lifecycle manager facility (ILM) is invoked to carry out movement of data from the hypervisor of a node of a computing cluster to a different storage location. Multiple nodes of the computing cluster can be hibernated until the entire computing cluster has been hibernated. The ILM observes a replication factor of the computing cluster to suppress saving multiple copies of data. A hibernation object comprising state information of a node is stored in a network-accessible storage location. The hibernation object is accessed in response to an instruction to initiate restoration of all or parts of the computing cluster. The hibernation object can be stored using first cloud computing storage infrastructure and later, can be restored to a different cloud computing infrastructure. Upon restoration, the hibernated cluster has the same state as of the time of hibernation.
