Abstract: A method commences upon receiving a request to migrate a subject virtual machine from a first computing machine to a second computing machine. An agent determines which storage assets are used by the subject virtual machine. The agent collects volume metadata pertaining to the storage assets and clones volume metadata from the first computing machine to the second computing machine. The data blocks comprising the volumes are not moved to the second computing machine until after migrating the subject virtual machine from the first computing machine to the second computing machine. After starting the migrated instance of the subject virtual machine, the migrated instance mounts volumes using the cloned metadata. The first computing machine and the second computing machine cooperate by processing storage asset block requests issued by the migrated virtual machine. Data blocks comprising the volume are moved on demand. The migrated virtual machine can be migrated yet again.

Abstract: Described is an approach for implementing stretching datastores/clusters in a virtualization environment. In this approach, data replication can be performed across multiple namespace protocols. In addition, control can be made of the granularity of the data replication such that different combinations of data subsets are replicated from one cluster to another.

Abstract: A method for providing backup to a networked virtualization environment for storage management by a remote storage environment having a block storage device and an object storage device, includes deploying a controller virtual machine at the remote storage environment, wherein the controller virtual machine provides a block storage device interface, receiving, at the controller virtual machine, a write request for data in a block-based format, translating the data from the block-based format to an object-based format, writing the data in the object-based format to the object storage device, and updating metadata corresponding to the write request in the block storage device.

Abstract: Described is an architecture for providing access to administrative functionality in a virtualization system using implied authentication. This approach avoids the problems associated with the requirements to use a user ID and password to access an admin console. The user ID and password can be rendered completely unnecessary, or where the user ID and password combination is only used as a supplement to the implied authentication.

Abstract: A method for leveraging hypervisor functionality for maintaining application consistent snapshots in a virtualization environment deployed by the hypervisor includes utilizing the hypervisor to generate a hypervisor-specific application consistent snapshot of a virtual machine running in the virtualization environment, taking a storage controller specific application consistent snapshot of the hypervisor-specific application consistent snapshot of the virtual machine, and logically deleting the hypervisor-specific application consistent snapshot.
