    摘要: Provided are a method, system, and article of manufacture for detecting data integrity. An indicator is written to invalidate a data block that is capable of being stored in a plurality of sectors of a storage device, wherein the indicator is written to the storage device in at least one sector that is not included in the plurality of sectors. A writing of entire contents of the data block to the plurality of sectors of the storage device is initiated, in response to the writing of the indicator. The indicator is updated to validate the data block, in response to a completion of the writing of the entire contents of the data block to the plurality of sectors of the storage device.

    摘要: Processor(s) operating a random access memory is subject to reboot processing which comprises clearing the random access memory. Registration is provided of a portion of the random access memory, the registration indicating that data stored in the registered portion of the random access memory is to be preserved during the reboot processing. In reboot processing, the processor responds to the registration, preventing data stored in the registered portion from clearing during the reboot processing.

    摘要: A data saving device, system, and method rapidly and deterministically saves data of a computer system. The device may mark data that must be saved when the computer is shut down. In certain embodiments, a boot control module detects a condition requiring a rapid deterministic data saving operation, such as a power failure and reboots the computer, deterministically terminating all existing processes. Additionally, the boot control module loads a data transfer kernel in place of a standard operating kernel used for normal operation. The data transfer kernel supports a set of processes exclusively dedicated to saving data. The data transfer kernel configures the computer and storage devices for the data transfer and saves the marked data with a minimum of interruptions from other processes. Also, the data transfer kernel may shut down the computer and the storage devices after transferring data.

    摘要: A plurality of processing nodes in a storage system are partitioned into a plurality of logical processing units, wherein the plurality of logical processing units can respond to I/O requests from a host coupled to the storage system. At least two logical processing units are grouped, wherein data in a first storage coupled to a first logical processing unit of the least two logical processing units is mirrored by data in a second storage coupled to the second logical processing unit of the at least two logical processing units. In response to a failure of the first logical processing unit, an I/O request from the host is responded to via the second logical processing unit.

    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.
