摘要： An approach for managing a data package is provided. Network utilization is determined to exceed a threshold.A sender computer determines a hash digest of the data package by using a hash function selected based on central processing unit utilization.If the hash digest is in a sender hash table, then without sending the data package, the sender computer sends the hash digest and an index referring to the hash digest so that a recipient computer can use the index to locate a matching hash digest and the data package in a recipient hash table.If the hash digest is not in the sender hash table, then the sender computer adds the data package and the hash digest to the sender hash table and sends the data package and the hash digest to the second computer to check the integrity of the data package based on the hash digest.

摘要： A mechanism is provided for optimizing migration/copying of de-duplicated data from an internal storage system to a removable storage system. A preliminary number of clusters to be generated are determined for sets of data objects stored on the internal storage system based on a number of the sets of data objects. The preliminary number of clusters is generated based on shortest distances between the sets of data objects, each cluster comprising one or more sets of data objects and each set of data objects comprising one or more chunks of data. A chosen cluster is identified from a set of clusters by identifying a cluster having a greatest number of common chunks within as few sets of data objects. Responsive to an export-size of the chosen cluster failing to exceed the available storage capacity of the removable storage system, the chosen cluster is exported to the removable storage system.

摘要： The invention (Fig. 6) is directed to a method for reading files stored on a storage system. The storage system comprises storage means (104) storing a first set of files according to a predetermined data format and a cache memory (106) storing a second set of files, the second set of files being a subset of the first set of files. The storage system is configured to allow one or more remote systems (110, 120) for reading files stored on the storage means and/or on the cache memory. The method comprises: - receiving (602) from one or more remote systems at least one read request for reading a sequence of files; - determining (604), among the files of the sequence, whether one or more cached files are already stored on the cache memory and whether one or more remaining files are not already stored on the cache memory; - determining (606), within said one or more remaining files, an order according to which said remaining files should be read on the storage system, given locations of said remaining files as stored on the storage system according to said predetermined data format; - reading (608) said one or more remaining files on the storage system according to said order and storing the remaining files on the cache memory.

摘要： Provided are techniques for storing data. An Input/Output (I/O) command is received, wherein the I/O command includes a unique identifier that is associated with one region of a multi- format data store. The unique identifier is used to select an I/O channel from among multiple I/O channels, wherein each I/O channel is associated with a data format and with a region of the multi- format data store. The I/O command is forwarded to the selected I/O channel to access the region.

摘要： A method to select a deduplication protocol for a data storage library comprising a plurality of data storage devices configured as a RAID array, establishes a normal deduplication protocol, a RAID failure deduplication protocol, and a multiple storage device failure deduplication protocol. The method receives host data comprising a plurality of interleaved data blocks. If the system is operating without any storage device failures, then the method processes the host data using the normal deduplication protocol. If the system is operating with a storage device failure, then the method processes the host data using the RAID failure deduplication protocol. If the system is operating with multiple storage device failures, then the method processes the host data using the multiple storage device failure deduplication protocol.

摘要： A method to allocate resources in a data storage library comprising a plurality of data storage devices configured as a RAID array, by establishing a normal operation resource allocation, a RAID failure resource allocation, and a multiple storage device failure resource allocation. The method receives host I/O requests, and enqueues those host I/O requests. If the system is operating without any storage device failures, then the method processes host I/O requests using the normal operation resource allocation. If the system is operating with a storage device failure, then the method processes host I/O requests using the RAID failure resource allocation. If the system is operating with multiple storage device failures, then the method processes host I/O requests using the multiple storage device failure resource allocation.
