A grid-based approach for enterprise-scale data mining that leverages database technology for I / O parallelism and on-demand compute servers for compute parallelism in the statistical computations is described. By enterprise-scale, we mean the highly-automated use of data mining in vertical business applications, where the data is stored on one or more relational database systems, and where a distributed architecture comprising of high-performance compute servers or a network of low-cost, commodity processors, is used to improve application performance, provide better quality data mining models, and for overall workload management. The approach relies on an algorithmic decomposition of the data mining kernel on the data and compute grids, which provides a simple way to exploit the parallelism on the respective grids, while minimizing the data transfer between them. The overall approach is compatible with existing standards for data mining task specification and results reporting in databases, and hence applications using these standards-based interfaces do not require any modification to realize the benefits of this grid-based approach.

A data migration system supports a low-latency and reduced overhead data storage protocol for data storage sharing in a non-collision fashion which does not require inter-communication and permanent arbitration between data storage controllers to decide on the data placement / routing. The multiple data fragments of data sets are prevented from routing to the same storage devices by a multi-step selection protocol which selects (in a first phase of the selection routine) a healthy highest ranked drive enclosure, and further selects (in a second phase of the selection routine) a healthy highest-ranked data storage controller residing in the selected drive enclosure, for routing data fragments to different storage pools assigned to the selected data storage devices for exclusive “writing” and data modification. The selection protocol also contemplates various failure scenarios in a data placement collision free manner.
