We present three enhancements to graduated declustering, a mechanism for improving the performance robustness of I/O-intensive parallel programs. These enhancements are called write support, primary copies, and logical partitioning. They serve to increase the number of programs to which we can successfully apply graduated declustering. We describe their need, present their design and implementation, and evaluate their performance.
