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 root@ access.
• Portability between cloud providers.
• Ease of deployment similar to DBaaS.

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

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

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

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.

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. Our engineers can help you analyze your application performance needs and size the database cluster accordingly.

The FlashGrid architecture does not impose any strict limits on the database size. With 2 or 3 hyper-converged nodes up to 100 TB is practical. 100’s TB are possible with separate storage nodes.

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 (up to 224 cores) before adding more nodes. 2+2 redundancy across two availability zones may be used for extra HA. Clusters with 4+ nodes are possible for extra-large capacities.

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.

Oracle Database versions 19c, 18c, 12.2, 12.1, and 11.2 are supported. We test with the latest PSUs / RUs as they are released.

For database nodes, Oracle Linux 7/8 or Red Hat Enterprise Linux 7/8. Application servers and other database clients can run on any operating systems, including Linux and Windows.

Please see a feature-by-feature comparison of the two solutions.

FlashGrid is deployed through AWS Marketplace. The marketplace software fees include FlashGrid software license and technical support.

Yes. For cloud deployments, FlashGrid Technical Support Services cover the entire infrastructure stack and are included in the Marketplace fees.

Oracle licenses and support must be purchased directly from Oracle.
