Various strategies have been developed to assist in determining an effective data placement for a parallel database system. However, little work has been done on assessing the relative performance obtained from different strategies. This paper studies the effects of different data placement strategies on a shared-nothing parallel relational database system when the number of disks attached to each node is varied. Three representative strategies have been used for the study and the performance of the resulting configuration has been assessed in the context of the TPC-C benchmark running on a specific parallel system. Results show an increase in sensitivity to data placement strategy with increasing number of disks per node.
