    摘要： I/O bandwidth reduction using storage-level common page information is implemented by a storage server, in response to receiving a request from a client for a page stored at a first virtual address, determining that the first virtual address maps to a page that is a duplicate of a page stored at a second virtual address or that the first and second virtual addresses map to a deduplicated page within a storage system, and transmitting metadata to the client mapping the first virtual address to a second virtual address that also maps to the deduplicated page. For one embodiment, the metadata is transmitted in anticipation of a request for the redundant/deduplicated page via the second virtual address. For an alternate embodiment, the metadata is sent in response to a determination that a page that maps to the second virtual address was previously sent to the client.

    摘要： A variety of methods and apparatus are taught for providing dynamic distributed file system client authentication. One method for providing dynamic distributed file system client authentication within a distributed file system computing environment includes the steps of receiving an NFS request from an NFS client, determining whether the NFS client has an access status sufficient to perform the NFS request, and performing the NFS request when the NFS client has sufficient access status. In some embodiments, the NFS request includes a file handle representing a given file system available on the server computer system and a file operation to be performed upon the given file system. A server computer in accordance with one embodiment of the present invention is operable to provide dynamic NFS client authentication. The server computer includes a CPU, a RAM accessible by the CPU, a ROM accessible by the CPU, a network I/O port coupled with the CPU, a mass storage device accessible by the CPU, and a kernel implemented on the server computer. In addition, the server computer implements a dynamic NFS client authentication service operable to receive an NFS request from an NFS client and to authenticate the NFS client in relation to the NFS request. The dynamic NFS client authentication service considers factors such as time, date, identity of the NFS client, a nature of the NFS request, and a current status of a resource upon which the NFS request operates.

    摘要： Described herein is a novel technique for implementing a policy-based caching engine in a storage system cluster (cluster) to automatically implement volume caching at select nodes of the cluster in optimizing cluster performance. The novel caching engine may be implemented in a management console of the cluster storing policy information related to volume caching operations requested by the caching engine. Policy information may include node or cluster attributes, operational events, and a pre-defined cached volume configuration of import to the user. Based on the stored policy information, the caching engine may determine a set of nodes on which to initiate a volume caching operation and generate a request for such operation to be performed on a particular node. Only select nodes in the cluster may thus implement volume caching to thereby conserve processing resources for more critical operations at other select nodes in the cluster.
