The instability of the network and storage nodes may lead to the failure of the storage process in the network storage environment. In this paper, we establish the realibility model of the storage node availability, and the probability model of a success file block storage process, give the Store-After-Partition Strategy, compare the probabilities of a success file storage process at different partition granularities, and finally put forward the optimal strategy of file partition among network storage environment. This strategy is valuable for network storage facing massive files.
