2.1.1.2.1 Exascale Storage Configuration

This topic describes the Exascale storage objects created during system deployment.

During system deployment, one Exascale storage pool is created for each Exascale cluster defined on the OEDA Web UI Exascale page:

• The storage pool uses the Storage Pool Name and sizing details (Storage Pool Size and Storage Pool Size Type) specified on the Exascale page.

• The storage pool spans the Exadata storage servers specified in the Selected Cells list.

• The storage pool media type is derived from the type of Exadata storage servers in use. For example, an HC storage pool is created on High Capacity (HC) Exadata storage servers.

• To support the storage pool, an Exascale pool disk is created on each primary storage device in the Exadata storage servers. Each pool disk is uniformly sized as a fraction of the overall storage pool size specified on the Exascale page.

Additionally, Exascale vaults are created according to definitions specified in the OEDA Web UI on the Define Clusters page and the Create Database page.

To use Exascale storage, each compute cluster (database server cluster or VM cluster) in the Define Clusters page is associated with an Exascale cluster. An Exascale cluster can support multiple compute clusters. However, each compute cluster requires a separate vault to store the Oracle Grid Infrastructure shared clusterware files (Oracle Cluster Registry and voting disks). Consequently, one vault is created for each Exascale-enabled compute cluster.

Then, for each database that you define on an Exascale-enabled compute cluster, you can use the Available Vaults list on the Create Database page to place the Oracle Database files (data files, control files, log files, and so on) on a previously defined vault. Or, you can use the Add new Vault button to define a new vault to house the Oracle Database files.

During deployment, each vault that is created uses the Vault Name specified in the OEDA Web UI. The corresponding Vault Size is applied to the vault space provisioning attribute associated with the underlying storage pool media type. For example, if the vault is created on an Exascale cluster containing an HC storage pool, the spaceProvHC vault attribute is set to Vault Size.
