摘要： A system and method for clustered failover of storage appliances is provided. In the event of a failover of one storage appliance to a surviving storage appliance, the surviving storage appliance assumes the identity of the failed storage appliance. This assumption of the identifier is accomplished by activating a network interface controller or host bus adapter with a network address associated with the failed storage appliance and by mapping a iSCSI name from the failed storage appliance to the surviving storage appliance.

摘要： 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.

摘要： A system and method enabling transparent access to blocks, such as virtual disks, stored on a storage system using a file-based protocol. The system and method traps in-coming file-based protocol open commands to check for a predetermined modification to the file name. If the system and method detects the predetermined modification, then the virtual disk associated with the file name is exported to the client issuing the open command and the client receives a response from the storage system. The client, in response to receiving the response to the open command, creates a new device instantiation for reading and writing raw data to the virtual disk.

摘要： 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.
摘要翻译： 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，文件系统在托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。

摘要： A system integrates an intelligent storage switch with a flexible virtualization system to enable the intelligent storage switch to provide 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 may be embodied as a file system having a write allocator configured to provide a flexible block numbering policy to the storage switch that addresses volume management capabilities, such as storage virtualization.
