Ceph uses the CRUSH algorithm instead of a standard lookup table. What is its unique advantage?

1. A It utilizes an internal Artificial Intelligence engine to predict future traffic patterns and move data shards before hotspots occur.
2. B It calculates data placement deterministically using a hierarchical map of the cluster, allowing for sophisticated failure domain isolation.
3. C It achieves O(1) direct lookup performance for all requests by maintaining a perfectly synchronized global state on every disk controller.
4. D It implements a specialized transparent data compression layer that allows the cluster to store 5x more data on standard hardware nodes.
