    Abstract: A Multi-Pathing Optimization Module (MPOM) interfaces with a client to route a data access request along a most optimal path to a storage system serving data container stored on a striped volume set (SVS). The MPOM constructs and references a Location Data Structure (LDS) containing striping rules associated with the SVS, a list of network elements (N-blades) operatively connected to the client, and a list of disk elements (D- blades) sharing a node of the storage system with the listed N-blades. The MPOM executes a Client_Locate( ) function on a per data access request basis to identify the D- blade serving the volume which will receive the request. When possible, the MPOM routes the data access request directly to the N-blade sharing a node with the identified D-blade, thereby using the most optimal path from the client to the SVS.

    Abstract translation: 多路径优化模块（MPOM）与客户端接口将数据访问请求沿最佳路径路由到存储在条带卷集（SVS）上的数据容器的存储系统。 MPOM构造并引用包含与SVS相关联的条带规则的位置数据结构（LDS），可操作地连接到客户机的网络元件（N-blade）的列表以及共享节点的盘单元（D-刀片） 的存储系统与列出的N-blade。 MPOM在每个数据访问请求的基础上执行一个Client_Locate（）函数，以识别服务于接收该请求的卷的D刀片。 如果可能，MPOM将数据访问请求直接路由到具有所识别的D刀片共享节点的N刀片，从而使用从客户端到SVS的最佳路径。

    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 and method proxies data access commands acrossed a cluster interconnect between storage appliances and a cluster using a file-level protocol. Each storage appliance activates two ports per data access, a local port for data access requests directed to clients of the storage appliance and a proxy port for data access requests directed to the partner storage appliance. Clients utilizing multi-pathing software may send data access requests to either the local port of the storage appliance or the proxy port of the storage appliance. The system and method improves high availability, especially during a loss of connectivity due to non-storage appliance hardware failure.

    Abstract: A system and method for examining the content of a client file system stored on an exported lun is provided. A client agent interfaces with a client file system to detemine block layout information of data containers within the client file system. This block layout information is then transmitted to the storage system exporting the lun. The storage system utilizes the block layout information to generate a shadow volume utilizing the storage system's file system.

    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 translation: 系统将智能存储交换机与灵活的虚拟化系统集成，以实现对存储在系统上的信息的文件和块协议数据访问请求的有效服务。 在与交换机耦合的存储系统上执行的存储操作系统实现虚拟化系统，以通过以命名文件，目录和逻辑单元号逻辑地组织信息来向客户端提供统一的存储视图。 虚拟化系统被示例性地体现为具有写分配器的文件系统，该分配器被配置为提供一种灵活的块编号策略，该灵活的块编号策略以比以前的非均匀性更精细的粒度（例如，单个块）来处理诸如存储虚拟化的卷管理能力， 灵活的存储虚拟化方案。 灵活的块编号策略在提高写入效率和消除存储“热点”以及引人注目的时间点读数据映像（快照）机制方面也带来了实质性的好处。

    Abstract: A logical number (LUN) cloning technique separates data blocks referenced by a writable virtual disk (vdisk) from data blocks referenced only by a backing store to conserve storage resources of a storage system. The LUN cloning technique separates the writable vdisk data blocks from the backing store during periods of reduced processing activity and in a manner that does not interfere with storage service provided by the system.

    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。
