Abstract: A destination storage server, which may be a filer, mirrors a volume managed by a source storage server, which may also be a filer. According to an embodiment of the invention, changes made to the source volume are logged and persistently stored on a data container, such as a file, on the destination volume. The source storage server is coupled to clients that make data access requests to the volume. When an access request is made by a client, the request is written to a log on the source storage server. At the same time, the request is written to a data container on a volume managed by the destination storage server. Each source storage server coupled to the destination storage server has its own file on the volume.

Abstract: A method for detecting an un-bootable first computer is described. A failed first computer initiates a boot procedure, and the boot procedure is controlled by boot firmware of the first computer. A virtual interface is established by the boot firmware, the virtual interface having boot status data written therein as the failed computer boots. A second computer reads the boot status data in the virtual interface using a remote direct memory access procedure to access data in the virtual interface. The second computer determines, in response to the boot status data, if the boot procedure of the first computer failed, and if it failed performing a failover routine; and if it succeeded allowing the failed computer to complete its boot procedure. Another connection between the first computer and the second computer is opened, in response to the boot procedure succeeding, using higher level software than the boot firmware.

Abstract: A filer converts a traditional volume to a flexible volume by: creating an aggregate on storage devices other than the storage devices of the traditional volume; on the aggregate, creating a flexible volume large enough to store metadata describing files residing on the traditional volume; on the flexible volume, creating metadata structures that describe the files of the traditional volume, except that the metadata indicates that data blocks and indirect blocks are absent and must be fetched from another location. As the filer handles I/O requests directed to the flexible volume, the filer calculates physical volume block number (PVBN) addresses where the requested blocks would be located in the aggregate and replaces the absent pointers with the calculated addresses. After the absent pointers have been replaced, the filer adds the storage devices of the traditional volume.

Abstract translation: 文件管理器通过以下方式将传统卷转换为灵活卷：在除传统卷的存储设备之外的存储设备上创建聚合; 在集合上创建足够大的灵活卷以存储描述驻留在传统卷上的文件的元数据; 在灵活的卷上，创建描述传统卷的文件的元数据结构，但元数据指示数据块和间接块不存在，并且必须从另一个位置获取。 由于文件管理器处理指向灵活卷的I / O请求，文件管理器计算所请求的块将位于聚合中的物理卷块（PVBN）地址，并使用计算出的地址替换缺少的指针。 在缺少指针被替换之后，文件管理器添加了传统卷的存储设备。

Abstract: A system and method provides a remote direct memory access over a transport medium that does not natively support remote direct memory access operations. An emulated VI module of a storage operating system emulates RDMA operations over such a medium, e.g., conventional Ethernet, thereby enabling storage. Storage appliances in a cluster configuration utilize the non-RDMA compatible transport medium as a cluster interconnect.

Abstract: A method and system mirror flexible volumes in a circular or bi-directional configuration, without creating a deadlock. A source filer maintains a number of log files on a destination filer, where the number of log files is greater than or equal to the number of cache flush operations the primary filer performs between cache flush operations on the destination filer. The source filer can create the log files in advance. Alternatively or in addition, the source filer can create the log files as needed, i.e., the source filer can create a log file when the source filer flushes its cache. Once the destination filer flushes its cache, the log files created prior to the destination filer cache flush can be deallocated or reused.

Abstract: A system and method for monitoring cluster partner boot status over a RDMA-capable transport protocol is provided. Upon initialization, a storage system in a cluster generates a virtual interface connection using a predetermined and pre-assigned fibre channel identification and virtual interface number. The surviving storage system may then open a connection to this predetermined and predefined virtual interface connection and issue RDMA commands thereto. This surviving storage system may utilize the RDMA capabilities of the virtual interface protocol to obtain a set of boot statistics to determine whether the booting file or storage system is progressing normally.
