Multi-media interfaces increase the need for large image databases, supporting the capability of storing and fetching streams of data with strict synchronicity and isochronicity requirements. In order to fulfill these requirements, the GigaView parallel image server architecture relies on arrays of intelligent disk nodes, each disk node being composed of one processor and one disk. This contribution analyzes through simulation the real-time behavior of the GigaView, in terms of delay and delay jitter. For a high-end Gigaview architecture, consisting of 16 disks and T9000 transputers, we evaluate stream frame access times under various parameters such as load factors, frame size, stream throughput and synchronicity requirements.
