What is most valuable?

There are several features I've found valuable, including Exadata Hybrid Columnar Compression, Exadata Smart Scan Technology, and Smart Flash Cache.

How has it helped my organization?

We have dramatically improved performance for the batch jobs, after we moved from the traditional Oracle 11G databases to the new Exadata servers.

Performance has improved several-fold and moving (consolidating many small databases from smaller Linux/Unix servers into Exadata cluster) has resulted in lower production support cost and effort for BAU DBAs.

What needs improvement?

There were some minor problems moving databases to Exadata, but it was more a problem with the internal processes with my current employer.

For how long have I used the solution?

We've used it since August 2015.

What was my experience with deployment of the solution?

We've not had many issues with deployment, except for the minor issues involving moving databases.

What do I think about the stability of the solution?

No problems, we have not had any unplanned down-time or performance issues.

What do I think about the scalability of the solution?

We've had no problems with scalability.

How are customer service and technical support?

Customer Service:

Oracle was pretty good in original install and database clusters build, and was pretty helpful in all the requests and questions we posted to them.

Technical Support:

I would say technical support is very good. I have extensive working relationships with the Oracle consultants who were deploying the Exadata clusters at Worksafe. We have not had any really major issues with our Exadata clusters so far.

Which solution did I use previously and why did I switch?

Yes, I have worked as DBAs on traditional Oracle RDBMS versions 9I, 10G and 11G. My previous employer has deployed large DW database into Exadata with great success. Also, Worksafe has decided to move/consolidate many smaller servers/databases into large Exadata clusters. My opinion is that in both cases business users are pretty happy with the database performance and stability on Exadata servers so far.

How was the initial setup?

Initial set-up was a bit complex, but everything was resolved pretty quickly.

What about the implementation team?

Original implementation was done by Oracle, and I would rate the consultant competence as very high.

What's my experience with pricing, setup cost, and licensing?

I was not involved with pricing and licensing.

Which other solutions did I evaluate?

I was not involved in any before evaluation process.

What other advice do I have?

Exadata is very solid and robust machine, with great performance. Highly recommended for companies (who can afford it).
