Migration to cloud has cut database costs and simplified shared storage but still needs lower latency

The best features FlashGrid Cluster for Oracle RAC offers include shared storage, which is critical because for on-premise Oracle high availability clusters, I do not need FlashGrid. When I migrate to the public cloud, I need FlashGrid to provide that shared storage. It is easy to migrate from on-premise to cloud because the Oracle architecture does not change; the only difference is that in the public cloud, shared storage block was not available, but FlashGrid provides that feature to the Oracle RAC cluster. FlashGrid Cluster for Oracle RAC has positively impacted my organization cost-wise because by migrating to the cloud from my on-premise data center, I could consolidate the price structure for my storage and compute needs. Oracle RAC was the bottleneck for that because previously, without FlashGrid, I could not configure Oracle RAC in the public cloud, but with FlashGrid, I managed to consolidate costs for Oracle RAC infrastructure in the cloud. After migrating with FlashGrid, I have a substantial presence of Oracle RAC clusters in my data centers, around 50 RAC clusters across the U.S., and each was costing around $100,000 per year per cluster. However, I was able to migrate 25 of those clusters to the public cloud using FlashGrid, and the cost was reduced to $50,000 for those clusters, meaning I saved $50,000 per annum for the 25 instances. After installing and configuring FlashGrid in AWS cloud, I was able to reduce the storage cost substantially compared to my on-premise data center storage. I saved $50,000 per Oracle RAC cluster per annum using FlashGrid, which includes both storage cost, compute cost, and also manpower cost.

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.

Quotes from Members

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

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."

"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

"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."

Pricing and Cost Advice

Information not available

"IBM doesn't publish its prices, so it's hard to compare its pricing to know how costly it is."
