Experimental/analytical model of a placement algorithm that declusters relations across several parallel, independent disks. The declustering is done on a subset of the disks, and the choices involved are the number of disks to decluster onto, which relations to put where, and whether a relation should be cache-resident. Communications overhead limits the usefulness of declustering in some cases, depending on the workload. See boral:bubba.} }
