Cloud migrations have become faster and active-active databases achieve near-zero downtime

FlashGrid Cluster for Oracle RAC is very secure regarding its AI capabilities. Most products today rely on cloud migration or are connected to AI, so I believe it is quite safe. Of course, there is room for improvement. The accuracy and reliability of FlashGrid Cluster for Oracle RAC has been excellent. In my experience, the accuracy and reliability have been all positive, and I have no negative things to say about it. It is very helpful and secure. FlashGrid Cluster for Oracle RAC is deployed in my organization in a hybrid and private cloud environment. I use Azure and AWS as my cloud providers. My advice to others looking to use FlashGrid Cluster for Oracle RAC is that I believe a trial period for every database administrator would be valuable. Everyone might love the solution if given the opportunity to try it. I rate FlashGrid Cluster for Oracle RAC eight out of ten because while there is room for improvement, it was easy to navigate and accomplish automated infrastructure deployment, which was very helpful.

During failovers or site switches it integrates the storage and ensures the transition of your applications

In terms of interoperability and compatibility, every time new applications and database levels are released, a thorough compatibility check is conducted in PowerHA. IBM consistently ensures compatibility, especially in the open systems environment and within the Unix platform, where software compatibility challenges are prevalent. Regarding components controlled under PowerHA, IBM occasionally must address compatibility issues by providing fixes and releases. Despite this, the product exhibits stability. However, the main issue arises when components are updated, requiring IBM to release corresponding fixes. This process may take some time, but it is routinely addressed. Regarding product stability, PowerHA is generally reliable, with the only notable challenge being the need for fixes during component updates. It would be beneficial if the software had options for controlling and implementing an active-active setup, although PowerHA is primarily designed for active-passive configurations.

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The stability and performance of the cluster during testing were impressive."

"I saved $50,000 per Oracle RAC cluster per annum using FlashGrid, which includes both storage cost, compute cost, and also manpower cost."

"FlashGrid Cluster for Oracle RAC was very helpful in solving the shared disk problem."

"The most valuable features are that it's robust and reliable and that the CP memory can be updated in runtime."

"If there's no activation dependency in your organization, I would go for this solution as you can have one server with multiple virtualizations, which will give you a big ROI in the long run."

Cons

"I believe FlashGrid Cluster for Oracle RAC can be improved by providing better guidance on how to utilize it smoothly, especially regarding the learning curve."

"There is room for improvement in the area of migration or integration with existing on-premises infrastructure."

"One weakness is that there might be performance degradation once I install Oracle RAC in the public cloud using FlashGrid; that is one weakness I have encountered after migrating to the public cloud with FlashGrid."

"The initial setup could be simpler."
