Overview

It adopts a single node and separates the computing from the storage. Any computing node failure does not result in data loss. Thanks to the distributed multi-replica redundance storage technology and the snapshot backup feature, the storage node can prevent the shutdown of the physical servers and data loss risk resulted from other force majeure disasters. Compared to the dual-computer high-availability version, its cost decreases by half without a change in its performance.
