How Much Service Data Can a Data Warehouse Store?

Each node in a data warehouse cluster has a default storage capacity of1.49 TB, 2.98 TB, 4.47 TB, 160 GB, 1.68 TB, or 13.41 TB. A cluster can house 3 to 256 nodes and the total storage capacity of the cluster expands proportionally as the cluster scale grows.

To enhance reliability, each node has a copy, which occupies half of the storage space.

The GaussDB(DWS) system backs up data and generates indexes, temporary cache files, and run logs, which occupy storage space. Therefore, the actual storage space of each node is about half of the total storage capacity.
