Data distribution strategy of swift in space utilization background

In view of the large-scale storage requirements in current space utilizations, Swift object storage system is used to realize long-term storage of data, while satisfying reliability, high efficiency and persistence. For the special needs of space utilizations, the strategy of Ring, the important components of the Swift, need to be transformed to adapt to the unique hardware equipment. The experimental results show that the strategy can balance the total write amount of each node as much as possible while balancing the network load. In other words, it can extend the overall life of the equipment, and make the whole system more suitable for the space environment.
