The CLEO III experiment will collect on the order of 200 TB of data
over the lifetime of the experiment. The challenges facing CLEO III
are how to store such a large dataset.
Our storage format of choice is Objectivity/DB on top of a Hierarchical Storage
Manager. We will describe in detail our experiences with Objectivity and the
various design decisions we made to limit the complexity of our storage system
(device driver approach rather than direct coding to Objectivity, schema
evolution, user data, etc), given the resources a (relatively) small experiment
has, shortage of development personnel, uncertainty of the future of commercial
databases, and the use of commercial software in a long-term mission-critical
environment.
