In this paper we present the design and implementation of DPH, a storage layer
for cluster environments. DPH is a Distributed Data Structure  (DDS) based on
the distribution of a paged hash table. It combines main memory with file
system resources across the cluster in order to implement a distributed
dictionary that can be used for the storage of very large data sets with key
based addressing techniques. The DPH storage layer is supported by a
collection of cluster--aware utilities and services. Access to the DPH
interface is provided by a user--level API. A preliminary performance
evaluation shows promising results.
