    摘要: Mechanisms are provided for extending cache for an external storage system into individual servers. Certain servers may have cards with cache in the form of dynamic random access memory (DRAM) and non-volatile storage, such as flash memory or solid-state drives (SSDs), which may be viewed as actual extensions of the external storage system. In this way, the storage system is distributed across the storage area network (SAN) into various servers. Several new semantics are used in communication between the cards and the storage system to keep the read caches coherent.

    摘要: A mold assembly for insert-molding a heterogeneous object includes an upper mold and a lower mold. The upper mold includes a cavity for accommodating an insert object. The lower mold includes a rigid body and a resilient contact member for resting the insert object. The resilient contact member absorbs dimensional variations of the insert object during the insert molding process.

    摘要: Provided are a computer program product, system and method for managing Input/Output (I/O) requests to a storage device. A write request is received having write data for a logical address in the storage device. A determination is made as to whether preserve mode is enabled. A first entry is located in a volume control table for the logical address indicating a version number of the data in the storage device for the logical address and a first physical location in the storage device having the data for the logical address. The write data is written to a second physical location in the storage device. A second entry is added to the volume control table for the logical address to write in response to determining that the preserve mode is enabled. In response to determining that the preserve mode is enabled, the volume control table is updated to have one of the first and second entry for the logical address point to the second physical location and have the version number indicate a current version and to have the first or second entry not indicating the current version to indicate the first physical location and the version number indicate a previous version.
