摘要： A system for host-based virtualization optimizations in storage environments employing off-host virtualization may include a host, one or more physical storage devices, and an off-host virtualizer such as a virtualizing switch. The off-host virtualizer may be configured to aggregate storage within the one or more physical storage devices into a virtual storage device such as a logical volume, and to provide control data for the virtual storage device to the host. The host may be configured to use the control data to perform a function in response to an I/O request from a storage consumer directed at the virtual storage device, and to use a result of the function to coordinate one or more I/O operations corresponding to the I/O request.

摘要： A system for external encapsulation of a volume into a logical unit (LUN) to allow booting and installation on a complex volume may include a host, one or more physical storage devices, and an off-host virtualizer. The off-host virtualizer (i.e., a device external to the host, capable of providing block virtualization functionality) may be configured to aggregate storage within the one or more physical storage devices into a logical volume and to generate metadata to emulate the logical volume as a bootable target device. The off-host virtualizer may make the metadata accessible to the host, allowing the host to boot off a file system resident in the logical volume.

摘要： A method, system, computer system, and computer-readable medium for maintaining up-to-date, consistent copies of primary data without the need to replicate modified data when the data were modified as a result of an operation that is not an application-driven write operation captured during replication. Selected storage management operations are performed on the primary and secondary data stores at points in time when the data are the same to ensure that the data stored within the data stores remain consistent. These selected storage management operations include operations that produce modified data stored in the primary data store, where a portion of the modified data are not replicated to a secondary node. Other types of storage management operations are selected to be performed on both the primary and secondary data stores, where the operations do not directly change data in the primary data store, but may affect data stored in the primary data store.

摘要： A method and system are provided for emulating operating system metadata to provide cross-platform access to storage volumes. The method may include generating operating system metadata for a storage device, wherein the operating system metadata emulates a storage volume hosted under a first operating system. The method may further include making the operating system metadata available to a host computer system, wherein the host computer system runs the first operating system. The operating system metadata enables the host computer system to recognize the storage device as the storage volume hosted under the first operating system.

摘要： A method for identifying data for relocation in a multivolume file system. The method includes generating a file location map, the file location map containing a list of the locations of files that occupy space on each of a plurality of volumes of the file system, wherein The file system comprising least a first volume and a second volume. The method further includes updating the file location map in accordance with changes in a file change log for the file system, and identifying data residing on the first volume of the file system by scanning the file location map. Using the identified data, a ratio of per-file activity during a first time period relative to overall file system activity over a second time period is calculated to derive a file activity ratio for each of the files of the identified data. Files are then selected for relocation based on the file activity ratio.

摘要： The present disclosure provides for performing virus scans at a storage device that stores one or more virtual machine disk image files (VMDK files). A secure AV module can coordinate communication between a file system on the storage device, a file system (FS) decoder, and an anti-virus engine to perform a virus scan of files contained within a VMDK file. A secure AV module can determine a subset of files that include changed data, where the subset of files is stored in a file system volume within a VMDK file. The secure AV module can use an FS decoder to translate file addresses relative to the file system volume into file addresses relative to the network storage file system. A secure AV module can provide the network storage file system addresses of the subset of files to the anti-virus engine, which can perform a virus scan on the files.

摘要： Systems and methods for I/O fencing in a shared storage environment are provided. Prior to initiating an I/O request, when feasible, the current time from a local timer is compared to the current state of an interval obtained for the target device. As a result, a device reset occurring while the interval is viable does not arbitrarily end a multiphase I/O operation. However, a device reset occurring once the lease has expired results in a delay or termination of the multiphase I/O operation. As a result, multiphase I/O operations from initiating hosts that have lost contact with the shared storage environment are not allowed to corrupt the shared storage devices.
摘要翻译：提供了共享存储环境中I / O防护的系统和方法。在启动I / O请求之前，如果可行，将从本地定时器的当前时间与目标设备获得的间隔的当前状态进行比较。结果，间隔可行时发生的器件复位不会任意地结束多相I / O操作。然而，一旦租赁过期，设备复位就会导致多相I / O操作的延迟或终止。因此，发起主机与共享存储环境失去联系的多相I / O操作不允许损坏共享存储设备。

摘要： A system for dynamic logical unit (LUN) mapping includes a host and an off-host virtualizer. The off-host virtualizer may be configured to present a virtual storage device that includes one or more regions that are initially unmapped to virtual storage, and to make the virtual storage device accessible to the host. The host may include a storage software stack including a first layer configured to detect and access the virtual storage device as if the virtual storage device were mapped to physical storage. Subsequently, the off-host virtualizer may be configured to dynamically map physical storage and/or logical volumes to the virtual storage device.
