Embodiment Construction
[0032]Fig. 1 is the overall flow chart of the present invention
[0033] Step 1: Cluster division, numbering the internal nodes of each rack, and forming the entire cluster into multiple logical rings that are not intersecting each other.
[0034] Step 2: Divide the files to be stored and determine the number of data backups.
[0035] Step 3: Use a hybrid data storage method to select a storage location for the data block copy.
[0036] Fig. 2 is a flow chart of storing data in the third step of the present invention using a hybrid storage method.
[0037] 3.1: Initialize the number c of data blocks to be stored in the queue, where c=h.
[0038] 3.2: Point the current data block pointer t to the data block at the head of the queue.
[0039] 3.3: If t≤c, go to 3.4, otherwise go to 3.8.
[0040] 3.4: Determine the storage location for the k copies of the data block pointed to by the pointer t, and set the initial value of the copy number p of the data block to 1.
