Database High Availability Simplified

How can FlashGrid help with deploying a mission-critical application in the cloud?

FlashGrid offers HA database architecture that allows full control and the flexibility to meet future database and infrastructure requirements:

  • Active-active or Fail-over database clustering based on proven FlashGrid and Oracle clustering technologies.
  • Full control of sizing, patching/updates, and database features. You have the [email protected] access.
  • Portability between the cloud providers.
  • Ease of deployment similar to DBaaS.

How can FlashGrid help us with moving our existing Oracle databases to the cloud?

FlashGrid enables running Oracle RAC in the cloud by adding shared storage and advanced network capabilities. Even if you have been using only single-instance databases, consider using the FlashGrid/RAC solution to mitigate the lack of control over the compute and storage resources and to increase database availability. Additionally, FlashGrid Cloud Provisioning fully automates the process of configuring Oracle RAC clusters and allows creating a cluster in AWS or Azure cloud in less than two hours.

What are the benefits of running an Oracle RAC database with FlashGrid in a public cloud?

Public cloud uptime SLA covers only VM instance uptime. It does not cover software or OS patching, crashes, or corruption. Oracle RAC provides true database high availability with active-active redundancy between two or more database node VMs. If zero RTO and zero RPO are your targets then you should look at running Oracle RAC with FlashGrid.

Does FlashGrid provide an alternative to Oracle RAC?

No, the FlashGrid software does not replace or emulate any part of the RAC software stack. The FlashGrid software provides storage, network, and automation capabilities for running Oracle RAC in public clouds.

How much performance overhead does FlashGrid create?

Compared to a single-instance database, a RAC database has overhead for communication and data mirroring between the nodes. However, clustering adds CPU, memory, and disk resources that speed up parallel operations. The FlashGrid software itself consumes negligible amount of system resources.

Can a database cluster in the cloud match performance of our on-premises cluster?

Testing performed at FlashGrid and by our customers demonstrated performance levels matching or exceeding performance of high-end on-premises systems. See Performance Considerations section in the whitepapers for AWS and Azure. FlashGrid engineers can help you analyze your application performance needs and size the database cluster accordingly.

What is the maximum database size that FlashGrid can support?

The FlashGrid architecture does not impose any strict limits on the database size. We have customers running databases larger than 10 TB in the cloud.

How many RAC nodes per cluster can be supported?

The FlashGrid architecture does not impose strict limits on the number of RAC nodes. In most cases we recommend two or three nodes. To reduce network overhead we recommend increasing the size of the nodes before adding more nodes. 2+2 redundancy across two availability zones may be used for extra HA. Please contact us if you are interested in a configuration with 4+ nodes.

How can we migrate our data from on-premises to the cloud?

The migration process is similar to migrating a database between two datacenters. Depending on the size of the database and tolerable downtime, you can use one of the regular migration tools, such as RMAN backup/restore, export/import, or DataGuard replication.

Which public clouds are supported by FlashGrid?

AWS and Microsoft Azure clouds, including the Government Cloud regions, are fully validated and supported. Contact us if you need to use a different public cloud.

Which Oracle versions are supported?

Oracle Database ver.,, or and Oracle Grid Infrastructure ver. or We test with the latest PSUs as they are released.

Which operating systems are supported?

For database nodes, Oracle Linux 7 or Red Hat Enterprise Linux 7. Application servers and other database clients can run on any operating systems, including Linux and Windows.

How do we purchase FlashGrid licenses and support?

FlashGrid software is available via AWS Marketplace and via Azure Marketplace. The marketplace software fees include FlashGrid software license and technical support. Base 8x5 and Mission-Critical 24x7 support SLA options are available.

Will FlashGrid provide 24x7 technical support for a mission-critical deployment?

Yes. FlashGrid offers different support plans that include 24x7 support options. In addition to handling problems directly related to the FlashGrid software the FlashGrid Technical Support Services also cover 3rd-party components that the FlashGrid software integrates with and that are critical for operation of the cluster.

How about subscriptions in Government Clouds?

FlashGrid software is available via AWS Government Cloud Marketplace and via Azure Government Cloud Marketplace. Please note that in Azure Government Cloud the technical support subscription must be purchased directly from FlashGrid or from a FlashGrid partner. It is priced per database node per year.

Are Oracle licenses included?

Oracle licenses and support must be purchased directly from Oracle.
