   • You can sort unit specifications by CPU Cores , Memory (GiB) , Log Disk (GiB) , or IOPS.

   • You can also filter unit specifications by type, which can be Default or Custom .

   • In the Actions column, you can click Edit or Delete to manage unit specifications.

   Note

   If the cluster version of a tenant is earlier than OceanBase Database V4.0, you cannot view or modify the Log Disk (GiB) or IOPS columns.

   The following table describes the parameters.

   Parameter	Description
   Specification Name	The name of the unit specification to be added.

If the cluster version is OceanBase Database V4.0 or later, you can enable Advanced CPU Settings and configure CPU overprovisioning. Specifically, you can configure the minimum and maximum numbers of CPU cores for the unit specification. Note If the cluster version is OceanBase Database V4.0 or later, you must select at least 1 CPU core.
   Memory	The memory for the unit specification, in GiB. The minimum value is 1 GiB. You must enter an integer.
   More Settings (Optional)	You can enable this parameter and configure Log Disk (GiB) and IOPS. Note If the cluster version is earlier than OceanBase Database V4.0, you cannot configure Log Disk (GiB) or IOPS.
