The three elements are not redundant or superfluous. Feature selection algorithms attempt to directly prune out redundant or irrelevant features. Proliant servers offers advanced capabilities such as dual power supplies with redundant configuration support. Load balancing can be useful in applications with redundant communications links. Transmission networks are complex with redundant pathways. This allows the construction of high-availability multiply redundant database servers. This could make conventional input on devices such and even redundant. Each Aerial Platform is equipped with a triply redundant avionics system. The design was hierarchical with redundant communication links. These networks are intertwined and crisscrossed to create a redundant network. This rendered the satellite somewhat redundant and required replacement. This is critically important in redundant multicast topologies. Initially there was concern that the now largely redundant cranes would be demolished. The avionics suite was based on modular architecture with dual redundant MIL-STD-1553B digital databuses. It is a general rule that qualifiers conveying redundant information are not used.
