    Abstract: Systems and methods for storage resource and computation resource expansion. A method embodiment includes migrating a computing task from an external computing environment to a different computing/storage environment. The method commences by identifying a storage system having virtualized controllers and by identifying a computing device that performs a workload that interfaces with the storage system. The virtualized controllers execute in the second computing environment to manage access to storage target devices by accessing a storage target device identified by an IP address. A particular virtualized controller that is connected to the storage target device is selected and configured to process storage I/O from a migrated workload. A user virtual machine or user executable container is configured to execute the workload on one of the nodes in the computing and storage system within the second computing environment. After migration, the computing task from the external computing environment is discarded or decommissioned.

    Abstract: In one embodiment, a system includes host machines that form elements of the virtualization environment, and that include a hypervisor, a user virtual machine (UVM), a connection agent, and an I/O controller. The system further includes a virtual disk comprising a plurality of storage devices, the virtual disk being accessible by all of the I/O controllers. At least one of host machines receives a request associated with one of the elements using an application programming interface (API), and including a context-specific identifier. The host machine determines, using reflection, a type of the context-specific identifier and processes the request based on a mapping, according to the determined type, from the context-specific identifier to a unique identifier associated with the element.

    Abstract: An architecture for accessing data between different virtual disk formats. A virtual machine may be migrated or cloned from a first server that uses a first virtual disk format to a second server using a second virtual disk format. In response to an I/O request from the virtual machine, a real-time mapper compares the virtual disk format used by the virtual machine with the virtual disk format of the virtual disk that the request is directed to. If the formats are different, a set of mapping metadata is used to map between data of the different virtual disk formats. Due to the mapping being performed in real time, the virtual machine is able to operate upon the virtual disk without the need to perform a potentially costly format conversion of the virtual disk or the underlying data.

    Abstract: Disclosed is an improved approach to optimize link-based cloning in a virtualization architecture. In some approaches, each of the remote nodes is allowed to maintain its own snapshot of the linked/shared image. In this way, the processing power of each remote node can be used in a decentralized manner to administratively handle access to the shared data, rather than requiring the CPU resources of only the host node to centrally handle administrative access to the data. In addition, each of nodes can maintain copies of the shared image in a local cache. This allows the caching resources to also be decentralized, as each of the nodes can use its own caching resources to hold the shared data.

    Abstract: Performing a hot-swap of a storage device for a node in a virtualization environment having a plurality of storage devices, includes performing pass-thru of a storage manager managing the plurality of storage devices to a service virtual machine, such that the service virtual machine communicates with the plurality of storage devices without going through a storage software layer of its corresponding hypervisor, booting the hypervisor from a device other than the plurality of storage devices and performing the hot-swap of the storage device.
