The Design of a Storage Architecture for Mobile Heterogeneous Devices

Mobile computing devices such as smart PDAs and ultra-light laptops with several networking interfaces are becoming commonplace. The provision of networked data storage facilities will greatly extend their use. This paper looks at the design of a storage architecture for such devices. A two-level structure is proposed in which one component, the mobile memory cache (MMC), moves when the node is mobile. A prototype MMC was designed and evaluated. Preliminary results are presented which show that the system should be able to provide a high-performance service.
