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.

Abstract: A portion of a native memory is configured as a buffer within a native execution environment. Execution of a managed runtime code is initiated by a virtual machine. Data from a managed runtime memory of the virtual machine is marshaled by the virtual machine into the buffer. Control of execution is transferred from the managed runtime code to the native code. The native code is executed. The native code operates directly upon the marshaled data in the buffer.

Abstract: A technique for operating a computer system to support an application, a first application server environment, and a second application server environment includes intercepting a work request relating to the application issued to the first application server environment prior to execution of the work request. A thread adapted for execution in the first application server environment is created. A context is attached to the thread that non-disruptively modifies the thread into a hybrid thread that is additionally suitable for execution in the second application server environment. The hybrid thread is returned to the first application server environment.

Abstract: Systems and methods for throttling logging processes in presence of system resource contention. Logging processes that contend with non-logging processes for resources can sometimes be throttled to more equitably share system resources. A method embodiment commences by establishing a set of throttling rules that are to be observed by the logging processes running on the system. While logging processes and non-logging processes are running, a monitor records system resource usage and other system conditions. When a process manager determines that the resources consumed by the combination of the logging processes and the non-logging processes exceed a threshold, then any currently-applicable throttling rules fire so as to prescribe throttling levels.

Abstract: Illustrative systems and methods enable a virtual machine (“VM”) to be powered up at any hypervisor regardless of hypervisor type, based on live-mounting VM data that was originally backed up into a hypervisor-independent format by a block-level backup operation. Afterwards, the backed up VM executes anywhere anytime without needing to find a hypervisor that is the same as or compatible with the original source VM's hypervisor. The backed up VM payload data is rendered portable to any virtualized platform. Thus, a VM can be powered up at one or more test stations, data center or cloud recovery environments, and/or backup appliances, without the prior-art limitations of finding a same/compatible hypervisor for accessing and using backed up VM data. An illustrative media agent maintains cache storage that acts as a way station for data blocks retrieved from an original backup copy, and stores data blocks written by the live-mounted VM.

Abstract: A method for preventing a dirty virtual machine from executing on an undesirable host server includes receiving, by a caching module provided for a first host server that hosts a virtual machine, a write data that is of the virtual machine and that is to be cached for the first host server. The virtual machine uses a virtual hard disk supporting hyper-V Virtual hard disk (VHDX) and virtual hard disk (VHD) file formats or any virtual file format with uniquely identifiable metadata. In response to the receipt of write data, the caching module provided for the first host server changes metadata of virtual hard disk files to a custom format before the virtual machine migrates from the first host server to a second host server, and the virtual machine becomes dirty as a result. When the dirty virtual machine sends a migration request to the second host server, a caching module provided for the second host server checks whether the custom format of the virtual hard disk files is identifiable.
