Oracle Exadata Review

It has computing power at the storage level, which reduces latency.


What is most valuable?

Usually, the I/O operation is a more intensive and costly one. In any transaction processing, the I/O is a more expensive operation due to storage and better performance. That's where most of the latency and time would be spent in overall flow. Exadata has an additional service and computing power at the storage level as well which reduces this latency. Usually it's available only on the high-end machines.

Exadata as a platform is a complete solution, where you have CPU memory with an additional server and inter-cell storage. That's the beauty of Exadata; IOPS and good overall latency and that's why we like it. We use it for the transaction processing, especially for production.

What needs improvement?

In terms of improvement, related to other products when we were running down the physical servers, we ran into some issues. We are always on the latest stack so at this point of time we are self-sufficient. Once we deployed Exadata, we never had to look back, at least in recent times.

One improvement would be the limitation on the storage. For example, when we buy with a double or triple CN, it comes with some storage. Once we reach that point, we don't have any other option. This was in the old version. We don't know how it is improved in the current version; maybe there is a way to optimize it and we can have additional storage allocated. In the earlier versions, we didn't have this possibility and we need to upgrade to a later version of Exadata to get more storage.

For how long have I used the solution?

I have used this product for more than 4 or 5 years.

What do I think about the stability of the solution?

It's a stable solution but it comes with a price. You get performance and there is a cost associated with the performance. The Exadata tool is best when you can afford. You get best quality, in terms of the overall product features.

What do I think about the scalability of the solution?

It depends on each case, your use and the company. For us, it is scalable and working for our use.

For me, what we have right now is scalable and it is serving our purpose.

How is customer service and technical support?

They have a dedicated team exclusively for Exadata. Whenever we ran into some issues with the tool, they nailed it down. The support was good in Oracle because this is a prestigious product from Oracle. They have their support model.
