    摘要： An apparatus in one embodiment handles service requests over a network, wherein the network utilizes a protocol. In this aspect, the apparatus includes: a) a network subsystem for receiving and transmitting network service requests using the network protocol; and b) a service subsystem, coupled to the network subsystem, for satisfying the network service requests. The network subsystem and the service subsystem being interconnected by a first unidirectional communication link for conveying data from the network subsystem to the service subsystem and by a second unidirectional communication link for conveying data from the service subsystem to the network subsystem. A variety of related embodiments are also provided, including file servers and web servers.

    摘要： A distributed file system and method distributes file system objects across multiple self-contained volumes, where each volume is owned by a unique file system node. Logical links are used to reference a file system object between volumes. Each file system node includes a relocation directory in which is maintained hard links to locally-stored file system objects that are referenced from another file system node using logical links. Various file system operations that involve multiple volumes are performed without having to place a write lock on more than one volume at a time. Various caching schemes allow the various file system nodes to cache file system object data and metadata.
