Abstract: A system and method employs one or more clients of a virtualized compute cluster as an execution engine for a portion of a storage operating system implemented as a virtual machine on a storage system node of a storage system cluster. If there is processing bandwidth of a client that is not fully utilized and the load on the storage system node is high, the portion of the storage operating system is ported to the client of the compute cluster in a manner that externally distributes the storage architecture from the storage system cluster. Advantageously, the processing performance of the storage system cluster is improved by, among other things, offloading some of the net- work processing load from the storage system node.

Abstract translation: 系统和方法使用虚拟化计算集群的一个或多个客户端作为在存储系统集群的存储系统节点上实现为虚拟机的存储操作系统的一部分的执行引擎。 如果客户端的处理带宽没有得到充分利用并且存储系统节点的负载较高，那么存储操作系统的部分将以从外部分配存储体系结构的方式移植到计算集群的客户端 存储系统集群。 有利的是，除了别的以外，存储系统集群的处理性能通过从存储系统节点卸载一些网络处理负载来改善。

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 system integrates an intelligent storage switch with a flexible virtualization system to enable efficient service of file and block protocol data access requests for in­formation stored on the system. A storage operating system executing on a storage sys­tem coupled to the switch implements the virtualization system to provide a unified view of storage to clients by logically organizing the information as named files, direc­tories and logical unit numbers. The virtualization system is illustratively embodied as a file system having a write allocator configured to provide a flexible block numbering policy that addresses volume management capabilities, such as storage virtualization, at a finer granularity (e.g., a single block) than that of previous non-flexible storage virtu­alization schemes. The flexible block numbering policy also yields substantial benefits in terms of increased write efficiency and elimination of storage "hot spots", as well as a compelling point-in-time read-only data image (snapshot) mechanism.

Abstract: A storage virtualization selection technique “automates” a virtualization selection process to create virtual disk (vdisk) storage objects over a volume of a file system implemented by a storage operating system of a multi-protocol storage appliance. The file system provides a virtualization system that aggregates physical storage of a set of disks 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, thus, inherits the underlying reliability configuration associated with that volume. The portions are aggregated and allocated as a vdisk with reliability guarantees in response to a request to create the vdisk from a user of the storage appliance and without further user involvement.

Abstract translation: 存储虚拟化选择技术“自动化”虚拟化选择过程以通过由多协议存储设备的存储操作系统实现的文件系统的卷创建虚拟磁盘（虚拟磁盘）存储对象。 文件系统提供了一个虚拟化系统，其将一组磁盘的物理存储或磁盘的部分（例如，扩展盘）聚合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。 然后，虚拟磁盘在卷内创建为存储对象，从而继承与该卷关联的底层可靠性配置。 这些部分被聚合并分配为具有可靠性保证的虚拟磁盘，以响应从存储设备的用户创建虚拟磁盘的请求，并且不需要进一步的用户参与。

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.

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.
