Abstract: As seen in Figure 1, a storage virtualization selection technique "automates" a virtualization selection process to create virtual disk (vdisk) storage objects over a volume (150) & (160) of a file system implemented by a storage operating system (200) of a multi-protocol storage appliance (100). The file system provides a virtualization system that aggregates physical storage of a set of disks (130) or portions (e.g., extents) of disks into a pool of blocks that can be dynamically allocated to form a vdisk. The file system also provides reliability guarantees for the vdisks in accordance with its underlying architecture. That is, the file system organizes its storage within volumes created among the managed disks. The vdisk is thereafter created as a storage object within a volume and inherits the underlying reliability configuration associated with that volume.

Abstract translation: 如图1所示，存储虚拟化选择技术“自动化”虚拟化选择过程以通过由存储操作系统（200）实现的文件系统的卷（150）和（160）来创建虚拟磁盘（虚拟磁盘）存储对象， 的多协议存储设备（100）。 文件系统提供虚拟化系统，其将一组磁盘（130）或部分（例如，扩展盘）的物理存储集中到可以动态分配以形成虚拟磁盘的块池中。 文件系统还根据其基础架构为虚拟磁盘提供可靠性保证。 也就是说，文件系统在受管磁盘之间创建的卷内组织其存储。 之后，该虚拟磁盘创建为卷内的存储对象，并继承与该卷关联的底层可靠性配置。

Abstract: A multi-protocol storage appliance serves file and block protocol access to information stored on storage devices in an integrated manner for both network attached storage (NAS) and storage area network (SAN) deployments. A storage operating system of the appliance implements a file system that cooperates with novel virtualization modules to provide a virtualization system that “virtualizes” the storage space provided by the devices. Notably, the file system provides volume management capabilities for use in block-based access to the information stored on the devices. The virtualization system allows the file system to logically organize the information as named file, directory and virtual disk (vdisk) storage objects to thereby provide an integrated NAS and SAN appliance approach to storage by enabling file-based access to the files and directories, while further enabling block-based access to the vdisks.

Abstract: A method and apparatus are disclosed for restoring a virtual disk (vdisk) in a data storage system as the vdisk was at an earlier time. Pointers are maintained to point to data represented by the vdisk. The pointers are saved to persistent storage at the earlier time. The data at the earlier time is maintained on the data storage device. A pointer pointing to data represented by the vdisk at a later time is compared with the pointers saved at the earlier time. If the pointer from the later time matches the pointer saved at the earlier time, keeping the pointer from the later time in the active file system. If the pointer from the later time does not match the pointers saved at the earlier time, copying a set of pointers associated with the pointer saved at the earlier time to the active file system.

Abstract: A multi-protocol storage appliance serves file and block protocol access to information stored on storage devices in an integrated manner for both network attached storage (NAS) and storage area network (SAN) deployments. A storage operating system of the appliance implements a file system (320) that cooperates with novel virtualization modules to provide a virtualization system (300) that “virtualizes” the storage space provided by the devices. The file system provides volume management capabilities for use in block-based access to the information stored on the devices. The virtualization system (300) allows the file system to logically organize the information as named file (324), directory (326) and virtual disk storage objects (322, 328) to thereby provide an integrated NAS and SAN appliance approach to storage by enabling file-based access to the files and directories while further enabling block-based access to the virtual disks.
