摘要： A method and system for acquiring a quiesceing set of information associated with a virtual machine. A virtual machine is cloned. The cloned virtual machine has an associated persistent storage device. The state of the persistent storage device is transformed into a quiesced state of the cloned virtual machine by utilizing a shut-down process. The shut-down process is executed on the cloned virtual machine to quiesce the cloned virtual machine and the quiesceing set of information of the cloned virtual machine is automatically reduced to information stored on the persistent storage device.

摘要： Interfaces to storage devices that employ storage space optimization technologies, such as thin provisioning, are configured to enable the benefits gained from such technologies to be sustained. Such an interface may be provided in a hypervisor of a virtualized computer system to enable the hypervisor to discover features of a logical unit number (LUN), such as whether or not the LUN is thinly provisioned, and also in a virtual machine (VM) of the virtualized computer system to enable the VM to discover features of a virtual disk, such as whether or not the virtual disk is thinly provisioned. The discovery of these features enables the hypervisor or the VM to instruct the underlying storage device to carry out certain operations such as an operation to deallocate blocks previously allocated to a logical block device, so that the storage device can continue to benefit from storage space optimization technologies implemented therein.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When traffic through a particular protocol endpoint is busy, the logical storage volume undergoes a rebind process pursuant to which the logical storage volume is bound to a new protocol endpoint, and the binding to the old protocol endpoint is removed upon completion of all pending input-output commands issued through the old protocol endpoint.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When a virtual machine is provisioned, logical storage volumes include a logical metadata storage volume and logical data storage volumes. The logical metadata storage volume stores metadata for the virtual machine such as configuration and log files, swap file, and disk descriptor files. Each disk descriptor file is provided for one logical data storage volume and stores metadata about the logical data storage volume such as size and unique identifying data.

摘要： In a computer system with a disk array that has physical storage devices arranged as logical storage units and is capable of carrying out hardware storage operations on a per logical storage unit basis, the hardware storage operations can be carried out on a per-file basis using various primitives. These primitives include instructions for zeroing file blocks, cloning file blocks, and deleting file blocks, and these instructions operate on one or more files defined in a blocklist, that identifies the locations in the logical storage units to which the files map.

摘要： A computer has access to a system-formatted data storage unit (DSU) containing a file system and to a raw DSU. A file within the file system constitutes a raw DSU mapping that facilitates access to the raw DSU. The raw DSU mapping appears to be an ordinary file to a storage user, but with the size of the raw DSU. An attempted access to the raw DSU mapping is translated into a corresponding access to the raw DSU. Access to the raw DSU by the storage user may be restricted to a specified region of the raw DSU, by defining an extent within the raw DSU mapping. The raw DSU mapping provides access to the raw DSU with many of the advantages of using a file system, including name persistency, permissions, persistent attributes, locking information for a distributed file system and other extended metadata.
摘要翻译： 计算机可以访问包含文件系统和原始DSU的系统格式的数据存储单元（DSU）。 文件系统内的一个文件构成一个原始DSU映射，便于访问原始的DSU。 原始DSU映射似乎是存储用户的普通文件，但具有原始DSU的大小。 对原始DSU映射的尝试访问被转换为对原始DSU的相应访问。 存储用户对原始DSU的访问可以通过定义原始DSU映射中的范围来限制到原始DSU的指定区域。 原始DSU映射提供对原始DSU的访问，具有使用文件系统的许多优点，包括名称持久性，权限，持久属性，分布式文件系统的锁定信息和其他扩展元数据。

摘要： The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. Logical storage volumes are created from a logical storage container having an address space that maps to storage locations of the physical data storage units. Each of the logical storage volumes so created has an address space that maps to the address space of the logical storage container. A logical storage container may span more than one storage system and logical storage volumes of different customers can be provisioned from the same logical storage container with appropriate security settings.

摘要： The storage system exports logical storage volumes that are provisioned as storage objects within logical storage containers. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. A snapshot profile can be separately defined for each of these logical storage volumes, even for those that are within the same storage container. The snapshot profile for a logical storage volume defines whether or not snapshot is enabled for that logical storage volume, the frequency of the snapshot, and the number of snapshots to be retained.
