Patent number: 10007540Abstract: A host machine may host a virtual machine. Virtual machine reboot information, used to reboot the virtual machine in the event of a failure or restart of the virtual machine, may be identified (e.g., file system metadata buffers, a virtual non-volatile random access memory log, user data buffers, and/or data used to reboot the virtual machine such as to perform a reboot mounting operation and/or a reboot replay operation of a volume of data associated with the virtual machine). The virtual machine reboot information may be cached within relatively fast host memory of the host machine (e.g., instead of merely within a relatively slower hard drive or other storage device). In this way, the cached virtual machine reboot information may be quickly retrieved so that the virtual machine may be rebooted in a relatively shorter amount of time.Type: GrantFiled: May 9, 2017Date of Patent: June 26, 2018Assignee: NetApp, Inc.Inventors: Ameya Prakash Usgaonkar, Mangesh Chitnis, Shehbaz Jaffer

Patent number: 9990239Abstract: A system and method for cooperative notification offloading supports thread notification offloading in a multi-threaded messaging system such as a distributed data grid. Pending notifiers are maintained in a collection of pending notifiers. A signaling thread processes a first notifier in the collection of pending notifiers to wake a first thread. The first awoken thread processes additional notifiers in the collection of pending notifiers to wake additional threads. The additional awoken threads can process additional notifiers in a cycle until all pending notifiers in the collection are processed. Such cooperative notification offloading of notifier processing from the signaling thread improves performance of the signaling thread with respect to other tasks thereby improving performance of the signaling thread and the distributed data grid.Type: GrantFiled: September 16, 2015Date of Patent: June 5, 2018Assignee: ORACLE INTERNATIONAL CORPORATIONInventor: Mark Falco
