What is our primary use case?
All business Oracle databases were spread across many DB servers and different platforms. We consolidated all of our databases onto a single Exadata box to ensure that they were running on the same platform and have greater coordination and integration between the databases. Also, we gained performance without much change in the database code, as well as saved a greater amount of space by applying the compression feature.
How has it helped my organization?
We experienced a significant performance improvement without changing the code, simply utilizing Oracle Exadata standard smart features including Smart Scan, Smart Flash Cache, and Storage Indexes.
We saved a great amount of storage by applying different levels of HCC and removing ninety percent of the indexes. This is a powerful and extremely stable system with IB network speed.
What is most valuable?
Most of the Exadata features are enabled by default, without the need for configuration. For example, the smart features include Smart Scan, Smart Flash Cache, Storage Indexes, and IB 40GB.
Compression is a great feature, where one can really save a lot of storage.
Oracle has introduced Machine Learning (ML), Artificial Intelligence (AI), and autonomous features for automatic database tuning. The new addition of X8M has come with a direct memory read future to deliver amazing performance for all sorts of OLTP and analytics workloads. This should benefit the Exa community.
What needs improvement?
General perception from many customers is the cost and maintenance of exadata database machine. Although Oracle recently introduced low cost storage and automated many features, still the cost and maintenance is a concern. Oracle should provide free of cost the Exadata software on the box to have more customers.
For how long have I used the solution?
We have been using this solution for more than eight years.
What do I think about the stability of the solution?
Every component in the Oracle Exadata database is redundant. Hence, it provides HA for every layer.
What do I think about the scalability of the solution?
This solution offers the flexibility to add more servers, storage servers, or a combination of both.
How are customer service and technical support?
Oracle support service needs more improvement.
Which solution did I use previously and why did I switch?
We haven't used Engineered Systems for Oracle database platforms, though, we were on various platforms that were difficult to manage and maintain.
How was the initial setup?
The bare metal setup is done by Oracle professionals and managed by them. Though, customers can manage this on their own, depending on the skill set of their team.
What about the implementation team?
Our implementation was done on-site, through the vendor.
What was our ROI?
We realize ROI through higher throughput, high availability, and business continuity.
What's my experience with pricing, setup cost, and licensing?
Exadata is an expensive tool, but, considering the ROI, it's worth going for the solution.
Which other solutions did I evaluate?
We compared other market players of Engineered systems. However, Oracle Exadata features are unmatched by other players in the market.
What other advice do I have?
Oracle is coming out with many advanced hardware additions and software solutions to make this product the world's best database machine.
Which deployment model are you using for this solution?
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
