This topic describes the built-in resource unit specifications of OCP. A tenant occupies resources of an OceanBase cluster in units. The size and quantity of resource units determine the amount of resources a tenant can use. You can choose to customize the resource unit specifications or use the built-in ones described in this topic. Built-in resource unit specifications cannot be modified.
OCP provides the following set of resource unit specifications:
Specification Name |
Minimum CPU |
Maximum CPU |
Minimum Memory |
Maximum Memory |
|---|---|---|---|---|
| B | 0.25 | 0.25 | 1GiB | 1GiB |
| LogOnlyNormal | 1 | 1 | 2GiB | 2GiB |
| LogOnlySystem | 5 | 5 | 35GiB | 35GiB |
| S0 | 0.5 | 0.5 | 2GiB | 2GiB |
| S1 | 1.5 | 1.5 | 6GiB | 6GiB |
| S2 | 3 | 3 | 12GiB | 12GiB |
| S3 | 6 | 6 | 20GiB | 20GiB |
| S4 | 12 | 12 | 40GiB | 40GiB |
Note
For OceanBase Database V2.0 and later, the minimum supported specification is S1.
Note
For an AI cluster (shared storage), the resource unit specification additionally includes the following fields:
- DATA_DISK_SIZE: The size of the cache disk space. Default value: MAX(min cpu * 2GB, memory size * 2). Minimum value: 2 * cpu (GB).
- MAX_NET_bandWIDTH: The maximum network bandwidth.
