摘要： In a method of updating software on a dormant disk, exposed files are accessed. The exposed files are exposed by mounting the dormant disk. The exposed files are scanned to determine the status of software residing on the dormant disk. The scanning is achieved without requiring booting of the dormant disk. It is determined whether an update is available for the software residing on the dormant disk.

摘要： A filter driver that is loaded during an initial part of the boot process enable operating systems that are not capable of booting from central storage to be booted from central storage. According to this technique, an initial set of operating system files is loaded into system memory from a local storage volume. The initial set of files includes a small subset of all of the operating system files and includes a boot loader, a kernel, boot time drivers, a file system driver, and a filter driver. The filter driver takes control over the loading of the remainder of the operating system files, so that these files are loaded from central storage instead of the local storage volume.

摘要： Virtual machines are managed in centralized manner. Files that are shared by multiple virtual machines are stored in a central storage unit and a management program is executed on one or more of these files on a per file basis. The management program is executed on a file if an IO operation is issued for that file. A namespace map is used to provide a mapping of filenames used by the different virtual machines to filenames used by the central storage unit.
摘要翻译：虚拟机以集中方式进行管理。由多个虚拟机共享的文件存储在中央存储单元中，并且在每个文件的基础上对一个或多个这些文件执行管理程序。如果为该文件发出IO操作，则管理程序在文件上执行。命名空间映射用于提供不同虚拟机使用的文件名与中央存储单元使用的文件名的映射。

摘要： A file management system includes a host computer having one or more virtual machines, a switching layer computer configured to manage a namespace map for the virtual machines in the host computer, and a central storage unit. The host computer is connected indirectly to the central storage unit through an in-band IO path that includes the switching layer computer and directly to the central storage unit through an out-of-band IO path. When a virtual machines issues a file operation, a file operation including a data operation is routed to the central storage unit along an out-of-band IO path and a file operation including a metadata operation is routed to the central storage unit along an in-band IO path that includes the switching layer computer.

摘要： Systems and methods for migration between computing machines are disclosed. The source and target machines can be either physical or virtual; the source can also be a machine image. The target machine is connected to a snapshot or image of the source machine file system, and a redo-log file is created on the file system associated with the target machine. The target machine begins operation by reading data directly from the snapshot or image of the source machine file system. Thereafter, all writes are made to the redo-log file, and subsequent reads are made from the redo-log file if it contains data for the requested sector or from the snapshot or image if it does not. The source machine continues to be able to run separately and simultaneously after the target machine begins operation.
