Abstract

[Seamless computing requires that people have ready access to their data at any time from anywhere. In theory, this could be achieved by placing all data in a shared repository, such as a network accessible file server, and having all applications on all devices access this single, shared database. In practice, such a centralized approach to data management is infeasible, except in limited situations, due to nonuniform network connectivity and latencies as well as device limitations and regulatory restrictions. For example, many handheld devices do not have wireless network capabilities, although this is rapidly changing. Even with wireless network adapters, devices may have restricted communication in environments such as airplanes and hospitals. Moreover, the high cost of wide-area wireless networking renders its use less desirable than local data access. Although all of the technology trends are in the right direction, ubiquitous, wide-area, low-cost, high-bandwidth, low-latency network communications are still many years away. Thus, for the foreseeable future, storage systems must provide the ability to replicate data close to its point of use, ideally colocated with applications running on a PC or mobile device.]
