Oracle Exadata Database Service on Dedicated Infrastructure Description

Learn how you can leverage the combined capabilities of Oracle Exadata and Oracle Cloud Infrastructure with Oracle Exadata Database Service on Dedicated Infrastructure

About Exadata Cloud Infrastructure

Exadata Cloud Infrastructure allows you to leverage the power of Exadata in the cloud.

You can provision flexible X8M and X9M systems that allow you to add database compute servers and storage servers to your system as your needs grow. X8M and X9M systems offer RDMA over Converged Ethernet (RoCE) networking for high bandwidth and low latency, persistent memory (PMEM) modules, and intelligent Exadata software. X8M and X9M systems can be provisioned using an shape equivalent to a quarter rack X8 or X9M system, and then database and storage servers can be added at any time after provisioning. For more information on X8M and X9M systems, see Overview of X8M and X9M Scalable Exadata Infrastructure.

Note

The RDMA software allows computers in a network to exchange data in main memory without involving the processor, cache, or OS of either computer. RDMA can improve throughput and performance because it frees up resources, and it can also facilitate a faster data transfer rate. RDMA over Converged Ethernet (RoCE) is the network protocol that allows RDMA over an Ethernet network.

X8 and X7 systems are also available in fixed-shapes (quarter, half, and full rack systems). These systems use InfiniBand networking, and do not have the ability to scale database and storage servers. You can also provision an Exadata base system, which has a smaller capacity than a quarter rack system.

For all Exadata Cloud Infrastructure instances, you can configure automatic backups, optimize for different workloads, and scale the OCPU and storage allocations as needed.

Note

Exadata Cloud Infrastructure instances launched on or after March 14, 2019 run Oracle Linux 7. Previously launched systems are running Oracle Linux 6. See To update the OS on all compute nodes of an Exadata Cloud Infrastructure instance for important information about updating existing Exadata DB system operating systems.

Subscription Types

Available subscription types.

The available purchase models are:
  • Pay As You Go

    Pay As You Go (PAYG) pricing lets customers quickly provision services with no commitment, and they’re only charged for what they use. There’s no upfront commitment and no minimum service period. Any cloud infrastructure (IaaS) and platform (PaaS) services consumed are metered and billed based on that consumption. If, during the services period of your order, Oracle makes new IaaS and PaaS services available within your cloud services account, Oracle will notify you of any fees that would apply to their activation and use. For more details, see our complete price list.

  • Annual Universal Credits

    Oracle Annual Universal Credits enables customers to have the flexibility to use any Oracle Cloud Infrastructure and platform services at any time, in any region, to deliver faster time to market. Customers can commit to an amount of Oracle Annual Universal Credits that can be applied towards the future usage of eligible Oracle IaaS and PaaS cloud services. This payment option offers a significant savings across cloud services, combining cost reduction and a predictable monthly spend with a ramp up period as you onboard your workloads.

See the Universal Credit Pricing FAQ for more information.

Metering Frequency and Per-Second Billing

Per-Second billing, minimums and limitations on billing.

For each Exadata Cloud Infrastructure instance you provision, you are billed for the infrastructure for a minimum of 48 hours, and then by the second after that. Each OCPU you add to the system is billed by the second, with a minimum usage period of 1 minute. If you terminate the cloud VM cluster and do not terminate the cloud Exadata infrastructure resource, billing will continue for the infrastructure resource.

Technical Architecture of Exadata Cloud Infrastructure Systems

Exadata Cloud Infrastructure systems integrate Oracle's Exadata Database Machine hardware with the networking resources needed to securely connect to your organization’s on-premise network and to other services in the Oracle cloud.

For a complete architectural overview of the components that make up an Exadata Cloud Infrastructure system, see Oracle Exadata Cloud Service (ExaCS) Technical Architecture. This interactive reference guides you through the key hardware and networking resources in the system, and provides technical specifications for the database (compute) and storage servers to help you plan for your deployment.

Scaling Options

Introduction to the Scaling option on Exadata Cloud Infrastructure.

Two kinds of scaling operations are supported for an Exadata Cloud Infrastructure:

  • For X8M and X9M systems, the flexible shape allows you to add additional database and storage servers to the cloud Exadata infrastructure resource as you need them. See Overview of X8M Scalable Exadata Infrastructure.
  • For X6, X7 and X8 Exadata DB systems, you can scale by moving the system to a different shape configuration, for example, from a quarter rack to a half rack.

For more information on each type of scaling, see Scaling an Exadata Cloud Infrastructure Instance.

Scaling CPU cores within an Exadata Cloud Infrastructure instance

If an Exadata Cloud Infrastructure instance requires more compute node processing power, you can scale up the number of enabled CPU cores symmetrically across all the nodes in the system as follows:

The options for each of the shapes are:

You can scale the infrastructure by adding DB servers or Storage Servers, up to the infrastructure limits. For more information on adding compute and storage resources to an X8M or X9M system emabled for MVM, see Scaling Exadata X8M or X9M Compute and Storage .

You can scale CPU cores in multiples of the number of database servers currently provisioned for the cloud VM cluster. For example, if you have 6 database servers provisioned, you can add CPU cores in multiples of 6. At the time of provisioning, X8M or X9M systems have as few as 2 database servers or up to to 32 database servers. For more information on adding compute and storage resources to an X8M or X9M system, see Scaling Exadata X8M or X9M Compute and Storage .

All systems that are not X8M or X9M are fixed shape systems. For a base system or an X7 or X8 quarter rack, you can scale in multiples of 2 across the 2 database compute nodes. For an X7 or X8 half rack, you can scale in multiples of 4 across the 4 database compute nodes. For an X7 or X8 full rack, you can scale in multiples of 8 across the 8 database compute nodes.

For a non-metered service instances, you can temporarily modify the compute node processing power (bursting) or add compute node processing power on a more permanent basis. For a metered service instance, you can simply modify the number of enabled CPU cores.

You can provision an Exadata Cloud Infrastructure instance with zero CPU cores, or scale the service instance down to zero cores after you provision it. With zero cores, you are billed only for the infrastructure until you scale up the system. For detailed information about pricing, see Exadata Cloud Service Pricing.

Note

OCPU scaling activities are done online with no downtime.

For information on CPU cores per configuration, see Exadata Shape Configurations. To learn how to scale a system, see To scale CPU cores in an Exadata Cloud Infrastructure cloud VM cluster or DB system .

Scaling X6, X7 and X8 Exadata Cloud Infrastructure Instances Configurations

Scaling an Exadata X6, X7, or X8 Exadata Cloud Infrastructure instance by moving to a shape with more capacity enables you meet the needs of your growing workload.

This is useful when a database deployment requires:

  • Processing power that is beyond the capacity of the current system configuration.
  • Storage capacity that is beyond the capacity of the current system configuration.
  • A performance boost that can be delivered by increasing the number of available compute nodes.
  • A performance boost that can be delivered by increasing the number of available Exadata Storage Servers.

You can move you workloads to a larger fixed shape (X7 and X8 hardware shapes), or move to the flexible X8M shape that allows for easy expansion of compute and storage resources as your workloads grow.

To assist with moving your database deployments between Exadata Cloud Infrastructure instances, you can restore a backup to a different service instance that has more capacity, or create a Data Guard association for your database in a service instance with more capacity, and then perform a switchover so that your new standby database assumes the primary role. To start the process, contact Oracle and request a service limit increase so that you can provision the larger service instance needed by your database.
