1.2.19.1 Inter-Vault Resource Management Using Exadata IORM

Inter-vault resource management defines how resources are allocated to different vaults. Inter-vault resource management uses Exadata IORM in conjunction with a vault plan, which controls resource allocation between Exascale vaults.

By default, each vault has access to all of the resources in the Exascale cluster. In this case, the vault plan shares resources equally across all vaults.

However, an Exascale administrator can set various vault-specific resource provisioning attributes, which may limit the space, I/O bandwidth (IOPS), and caching resources available to the vault. In this case, the vault plan is automatically derived from the vault definitions and propagated to every storage server in the Exascale cluster. Furthermore, the vault plan automatically adjusts with changes to the resource provisioning attributes. No additional administrator intervention is required.

On a system that uses Exascale and traditional Exadata storage based on Oracle Automatic Storage Management (Oracle ASM), the vault plan coexists with other parts of the IORM plan. For example, an Exadata administrator can still define an inter-database plan (dbplan) to manage resource allocation across databases using Oracle ASM. In this case, resources are shared equally between Exascale and Oracle ASM.
