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： 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： Input/output (I/O) activity in the multiple tier storage system is monitored to collect statistical information. The statistical information is recurrently transformed into an exponential moving average (EMA) of the I/O activity having a predefined smoothing factor. Data portions in the multiple tier storage system are sorted into buckets of varying temperatures corresponding to the EMA. At least one data migration plan is recurrently generated for matching the sorted data portions to at least one of an available plurality of storage device classes. One data portion sorted into a higher temperature bucket is matched with a higher performance storage device class of the available plurality of storage device classes than another data portion sorted into a lower temperature bucket.

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.

摘要： Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

摘要： An I/O enclosure module is provided with one or more I/O enclosures having a plurality of slots for receiving electronic devices. A host adapter is connected a first slot of the I/O enclosure module and is configured to connect a host to the I/O enclosure. A device adapter is connected to a second slot of the I/O enclosure module and is configured to connect a storage device to the I/O enclosure module. A flash cache is connected to a third slot of the I/O enclosure module and includes a flash-based memory configured to cache data associated with data requests handled through the I/O enclosure module. A primary processor complex manages data requests handled through the I/O enclosure module by communicating with the host adapter, device adapter, and flash cache to manage to the data requests.

摘要： Provided are a method, system, and computer program product for processing read and write requests in a storage controller. A host adaptor in the storage controller receives a write request from a host system for a storage address in a storage device. The host adaptor sends write information indicating the storage address updated by the write request to a device adaptor in the storage controller. The host adaptor writes the write data to a cache in the storage controller. The device adaptor indicates the storage address indicated in the write information to a modified storage address list stored in the device adaptor, wherein the modified storage address list indicates modified data in the cache for storage addresses in the storage device.
