Senior Database Administrator at a healthcare company with 10,001+ employees
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.

Useful ISS, good support, and simple implementation
There are times when we do the system security updates and have to restart the server which is difficult because we need to wait until the end of the day or when working hours are finished. There are service updates that have a requirement to restart the system and it is not convenient. In a feature release, there should be a feature to allow applications to be developed on the web portal and better databases that we can run.

Quotes from Members

Pros

"I saved $50,000 per Oracle RAC cluster per annum using FlashGrid, which includes both storage cost, compute cost, and also manpower cost."
"The stability and performance of the cluster during testing were impressive."
"FlashGrid Cluster for Oracle RAC was very helpful in solving the shared disk problem."
"Some of the advantages, are it can give you the ability to choose."
"The product is stable."
"The most valuable feature is the ability to easily create clusters supporting geo-redundancy."
"The reliability is pretty good."
"It's scalable, highly available, and is agile to handle workloads."
"Business continuity is much better, due to the possibility of patching/upgrading systems without interruption of services."
"The failover is the solution's most valuable aspect."
"The solution switches over to another server in case the server goes down."
 

Cons

"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."
"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."
"The product should be less dependent on network configuration."
"The stability is good, except for when something crashes or shuts down unexpectedly, then it can be a bit difficult to reestablish the service in a stable state."
"The standard, non-enterprise technical support could be improved."
"Technical support isn't as responsive as I'd like."
"There are times when we do the system security updates and have to restart the server which is difficult because we need to wait until the end of the day or when working hours are finished. There are service updates that have a requirement to restart the system and it is not convenient."
"The tool's pricing is high."
"We are currently looking for another solution because, in many industries, such as eCommerce, they operate 24 hours a day seven days a week and this solution has some downtime which our customers do not like."
"They could drop the price or improve the cost of the hyper-converged component of it all. Right now, licensing is expensive and complex."
