摘要： Provided are a method, system, and program for handling a fabric failure. A module intercepts a signal indicating a failure of a path in a fabric providing a connection to a shared device. The module generates an interrupt to a device driver in an operating system providing an interface to the shared device that is inaccessible due to the path failure. The device driver requests information from the module on a status of a plurality of devices that are not accessible due to the path failure and receives information indicating the inaccessible device. The device driver reconfigures to discontinue use of the inaccessible device.

摘要： A dual cluster storage server maintains track control blocks (TCBs) in a data structure to describe the data stored in cache in corresponding track images or segments. Following a cluster failure and reboot, the surviving cluster uses the TCBs to rebuild data structures such as a scatter table, which is a hash table that identifies a location of a track image, and a least recently used (LRU)/most recently used (MRU) list for the track images. This allows the cache data to be recovered. The TCBs describe whether the data in the track images is modified and valid, and describe forward and backward pointers for the data in the LRU/MRU lists. A separate non-volatile memory that is updated as the track images are updated is used to verify the integrity of the TCBs.
摘要翻译：双集群存储服务器维护数据结构中的轨道控制块（TCB）以描述存储在相应轨道图像或段中的高速缓存中的数据。在集群故障和重新启动之后，幸存的集群使用TCB来重建数据结构，例如分散表，其是标识轨迹图像的位置的哈希表，以及最近最少使用的（LRU）/最近使用的 MRU）轨道图像列表。这样可以恢复高速缓存数据。 TCB描述轨道图像中的数据是否被修改和有效，并描述LRU / MRU列表中的数据的前向和后向指针。随着跟踪图像被更新而更新的单独的非易失性存储器用于验证TCB的完整性。

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： Provided are a computer program product, system and method for managing Input/Output (I/O) requests to a storage device. A first entry is located in a volume control table for the logical address to write indicating a version number and a first physical location. 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 in response to preserve mode being 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 indicate a current version and to have the first or second entry not indicating the current version to indicate the first physical location and a previous version.

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： An apparatus, system, and method are disclosed for storing and retrieving compressed data. A compression module compresses a data file organized in logical tracks. A ratio module determines a track compression ratio. The track compression ratio is a ratio of an integer value n to one. A destage module destages a single directory entry for the data file to a directory. The directory entry points to a zeroth track on a hard disk drive. The destage module further destages the data file sequentially to tracks of the hard disk drive from the zeroth track with n logical tracks of the data file stored on one physical track of the hard disk drive. A stage module stages a kth logical track from a physical track of the hard disk drive. The physical track is specified by an integer value of k divided by n.

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 method for efficiently using a large secondary cache is disclosed herein. In certain embodiments, such a method may include accumulating, in a secondary cache, a plurality of data tracks. These data tracks may include modified data and/or unmodified data. The method may determine if a subset of the plurality of data tracks makes up a full stride. In the event the subset makes up a full stride, the method may destage the subset from the secondary cache. By destaging full strides, the method reduces the number of disk operations that are required to destage data from the secondary cache. A corresponding computer program product and apparatus are also disclosed and claimed herein.
