Data storage and delivery protocols to support interactive high-resolution image browsing on a PC-cluster based image-wall

We present a data storage, retrieval, and communications system capable of supporting high-resolution image browsing on an inexpensive PC cluster based image-wall system. The data is first partitioned and then strategically written both onto a single hard disk and then across multiple hard disks. After presenting the data allocation scheme, we present schemes for retrieving the data from the hard disks and neighboring renderers. The optimality of the storage and retrieval mechanisms is proved and analytical results are presented for an initial implementation.
