    Abstract: A system and method caches and distributes meta-data for one or more data con­tainers stored on a plurality of volumes configured as a striped volume set (SVS) and served by a plurality of nodes interconnected as a cluster. The SVS comprises one meta­ 5data volume (MDV) configured to store a canonical copy of certain meta-data, including access control lists and directories, associated with all data containers stored on the SVS, and one or more data volumes (DV) configured to store, at least, data content of those containers. In addition, for each data container stored on the SVS, one volume is desig­nated a container attribute volume (CAV) and, as such, is configured to store ("cache") a io canonical copy of certain, rapidly-changing attribute meta-data, including time stamps and container length, associated with that container.

    Abstract translation: 系统和方法为存储在被配置为条带卷集（SVS）的多个卷上并由作为集群互连的多个节点服务的一个或多个数据容器缓存并分发元数据。 SVS包括一个元5数据卷（MDV），其被配置为存储与存储在SVS上的所有数据容器相关联的某些元数据（包括访问控制列表和目录）的规范副本，以及一个或多个数据卷（DV），被配置为 至少存储那些容器的数据内容。 另外，对于存储在SVS上的每个数据容器，一个卷被指定为容器属性卷（CAV），并且因此被配置为存储（“缓存”）某些快速变化的属性元数据的io规范副本， 与该容器关联的数据，包括时间戳和容器长度。

    Abstract: An apparatus for data storage includes a cluster of NFS servers. Each server has network ports for incoming file system requests and cluster traffic between servers. The apparatus includes a plurality of storage arrays in communication with the servers. The servers utilize a striped file system for storing data. A method for data storage. A method for establishing storage for a file. A method for removing a file from storage. A method for reading data in a file. A method for writing data in a file.

    Abstract: An apparatus for handling file level and block level remote file accesses. The apparatus includes a block level server. The apparatus includes a file level server. The apparatus includes a storage layer implementing an inode layer performing inode operations, and storing data accessed by the file level and block level servers. The apparatus includes a management layer connected to the storage layer underlying the block and file level servers, which performs data management operations upon the underlying data. A method of handling file level and block level network file accesses. The method includes the steps of performing management operation by a management layer for a block level server and a file level server. Then there is the step of performing the servers' data accessing and updating operations using a vnode layer implemented on top of an inode layer. Then there is the step of storing data from the block level server or the file level server in a storage layer connected to the management layer (Fig 1).
