    摘要: A connection state system is described herein that allows a client to resume a connection with a server or a different replacement server by remotely storing client state information in association with a resume key. The system provides a resume key filter operating at the server that facilitates the storing of volatile server state information. The state information can include information such as oplocks, leases granted to a client, and in-flight operations on a file handle. The resume key filter driver sits above the file system, which allows multiple file access protocols to use the filter. Upon a failover event, such as a server going down or losing connectivity to a client, the system can bring up another server or the same server and reestablish state for file handles held by various clients using the resume key filter.

    摘要: An optical disk cassette has a cassette case with a disk retention device. A free end of the disk retention device acts upon an edge of the optical disk, opposably displacing during insertion and ejection of the optical disk. The device and disk are at equilibrium when the free end is displaced by the full diameter of the disk. When the disk is displaced in the insertion or ejection direction, the free end urges the disk in the insertion or ejection direction, assisting with the optical disk insertion or ejection respectively. Embodiments may have the disk retention device including one or more retainers. Each retainer may have a free end and opposing fixed end, and be flexible or have a flexible region. The free end slides along or otherwise contacts the circumferential edge of the optical disk, exerting a force upon it during optical disk insertion, retention and ejection.

    摘要: An apparatus comprising a first partition and a second partition. The first partition has a first file system comprising (i) a plurality of first clusters configured to store data having accesses faster than a first worst case data transfer rate and (ii) a dedicated space not used by the plurality of first clusters. The second partition has a second file system comprising a plurality of second clusters (i) configured to store data having accesses faster than a second worst case data transfer rate and (ii) occupying the dedicated space.

    摘要: An optical disk cassette has a disk eject mechanism that ejects a disk such as a DVD or CD. The disk eject mechanism has pushrod, transfer and kick out portions. The pushrod portion slides relative to a side of the cassette case. Pivotally mounted within the case, the kick out portion pushes a disk to eject it from the case. The transfer portion translates pushrod motion to motion of the kick out portion. In a preferred embodiment, the disk eject mechanism is a unitary body, with pushrod, transfer and kick out portions made homogeneously as a single entity, the pushrod portion being a resilient joining elbow. In another preferred embodiment, the disk eject mechanism has a transfer portion that is a rack and a pinion. The rack extends from the pushrod portion and the pinion is attached to or formed as part of the kick out portion.
