It's about consolidation of my infrastructure, scalability, high performance, and availability. These are the main factors that led me to choose this solution, as well as the cost. Exadata saves on my storage costs. All our costs were reduced significantly, and that was the reason why we went back to Exadata.
Room for Improvement:
On the improvement side, they’re pretty much good. With the latest version, X6-2, we have enhanced the storage capacity. It was 4 TB each disk, now it’s 8 TB each disk; essentially same size appliance with more storage space. That request has been heard and we're able to mitigate that. Increased storage was one thing and they have definitely done better on the IO of flash storage. They implemented that; pretty much good stuff.
We have not had any major problems with stability.
From time to time, we scale capacity up and out. In system engineering terms, we can scale up to limit. The kind of features we just set it up, I've been able to fit my requirements into that.
We have Oracle’s Platinum support, which has been pretty good. However, the people are not always knowledgeable. I always rely on my best contacts in Oracle to get the right support. Even though we have Platinum Support, my last delay was my contacts in Oracle.
Initial setup was very much straightforward. Not as much manpower is required as we used to need. Before, if you wanted to manage a server, you had to have a server administrator, the storage administrator, and a DBA administrator. Now all three functions are combined into one person. A data administrator can perform the role of storage administrator, your host administrator, platform administrator, as well as database administrator. It's like several persons reduced to one.
I would definitely recommend this product if cost is not a factor. The implementation costs are, frankly, higher, but your return on investment over a period of time is less. If you're looking for that, then I would definitely advise to go for this product.
