- Abstract
For distributed storage based on data replication, an optimal data placement is vital to minimize the variance of the number of available files. Well-balanced triple systems and nearly well-balanced triple systems (NWBTSs) were proposed to produce optimal data placements for triple replication. This article concentrates on the existence of NWBTSs. By constructing candelabra systems with various desirable partitions, many new constructions for NWBTSs are developed. The main result of this paper is that there always exist optimal data placements for triple replication on a v-set for all positive integers v possibly except when v ≡ 4 (mod 24) or v = 50 , 74 .
