Systems and methods for dynamic context based data protection and distribution are described herein. In the method data replication in a multi-zone storage system automatically changes based on historical storage trends and/or external information obtained from third party information sources, such as feeds, websites, news alerts, emergency alerts, weather alerts and databases. The methods include monitoring third party information sources and evaluating a correlation between event data from the third party information sources and key words that are user provided and/or system derived. A correlation between the event data and data storage history is evaluated. A storage policy is derived based on the results of the correlation evaluation(s). The derived storage policy and corresponding key words are stored in a database. Data is stored in storage arrays according to storage policies corresponding to the key words identified in the data.

Dynamic data protection and distribution responsive to external information sources

An object based file system for storing and accessing objects is disclosed. The file system may be implemented as a method in hardware, firmware, software, or a combination thereof. The method may include receiving from an application program an object write request. A selected storage node on which to store the object may be selected, including identifying a least busy storage node and/or a least full storage node. The object and the object write request may be sent to the selected storage node. A write success message may be received from the selected storage node. The successful writing of the object may be reported to the application program.

A system for data migration between high performance computing architectures and data storage disks includes an intermediate data migration handling system which has an intermediate data storage module coupled to the computer architecture to store data received, and a data controller module which includes data management software supporting the data transfer activity between the intermediate data storage module and the disk drives in an orderly manner independent of the random I/O activity of the computer architecture. RAID calculations are performed on the data prior to storage in the intermediate storage module, as well as when reading data from it for assuring data integrity, and carrying out reconstruction of corrupted data. The data transfer to the disk drives is actuated in sequence determined by the data management software based on minimization of seeking time, tier usage, predetermined time since the previous I/O cycle, or fullness of the intermediate data storage module. The storage controller deactivates the disk drives which are not needed for the data transfer.
