Modelling and storage allocation strategies for homogeneous parallel access storage devices in real time multimedia information processing

Improvements in disk speed have not kept up with improvements in processor and memory speed. Conventional storage techniques, in the face of multimedia data, are inefficient and/or inadequate. An efficient multimedia object allocation strategy is presented. We describe a multimedia object model, the object and storage device characteristics, and the fragmentation strategy. A bipartite graph approach is used for mapping fragments to storage devices and a cost value is used to determine an efficient allocation of an object and to balance the loads on the devices
