    摘要: A write-once-read-many (WORM) storage system that employs large-capacity and relatively inexpensive disks in connection with a file system on a file server is provided. The file system contains most or all of the required WORM functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files that, when committed to WORM storage, cannot be deleted or modified. Any file path or directory tree structure used to identify the file within the WORM volume is locked and cannot be deleted. In one embodiment, the administrator creates a WORM volume, capable of storing designated WORM files. The client then creates an appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state. The- file system recognizes the persistently stored WORM attribute of any file in a WORM volume as WORM file. Henceforth, any attempt to modify the file attributes, write to the file, or delete the file, by clients, administrators or other entities is rejected and a request denied message is returned to the attempting party

    摘要: A suspension for, and a method for suspending, a vehicle having a body is provided. The suspension includes a first suspension assembly and a second suspension assembly. The first suspension assembly extends between a first surface contact assembly and the body, and the second suspension assembly extends between a second surface contact assembly and the body. The first and second suspension assemblies each have a transverse instant center. The first suspension assembly and the second suspension assembly are aligned so that a vertical centerline of each surface contact assembly lies within a transverse vertical plane that extends therebetween. The transverse instant center of each suspension assembly is located within the transverse vertical plane, below a roll center located within the transverse vertical plane.

    摘要: A lightweight coherency control protocol ensures consistency of data containers, such as a file, and associated data buffers stored on one or more volumes served by a plurality of nodes, e.g., storage systems, connected as a cluster. Each data buffer is associated with a current cache sequence number comprising a load generation value and an update count value. The load generation value is incremented every time an inode of a file is loaded into a memory of the storage system. Once the inode is loaded and its load generation value is set, then the appropriate buffer of a buffer tree for the file is loaded into the memory. The update count value is incremented each time the buffer is updated with a write request/operation. Therefore, each buffer loaded into memory is tagged with the load generation value and an update count from the time that buffer is loaded.

    摘要: A flexible data storage card and shutter lock is disclosed. The flexible data storage card includes a housing, a media disc, a shutter, and a shutter lock. The housing includes a card top coupled to a base to define an enclosed region, and an access window defined by the base and communicating with the enclosed region. The media disc is rotatably disposed within the enclosed region. The shutter is slidably disposed within the enclosed region and defines a shutter window selectively alignable with the access window. The shutter lock is disposed within the enclosed region and is selectively couplable with the shutter.
