Welcome to the Ask the Expert conversation. On this occasion our topic is going to be Oracle on XtremIO, EMC’s all-flash array. We have a 20 minute video [available soon] that takes you through the advantages of using XtremIO for Oracle. Don’t have time for the video? No problem as this is an open discussion in which you can ask any question you would like and our team of Oracle Specialists and Technical Marketing DBAs will provide you with answers. We also welcome your opinions and ideas about all things all flash.

Thanks for posting this the event! We really look forward to discussing Oracle on XtremIO. We are also very excited to have Matt Kaberlein from the Oracle Specialist team leading the event as he has a wealth of experience in working closely with customers on using EMC's XtremIO all-flash array.
So, I’m going to get the discussion started by talking about the importance of array testing. All flash arrays like XtremIO demand different approaches to performance testing because of features like inline data reduction, all zero optimization, and compression. Tools like btest and vdbench enables customers to run performance tests with unique data so array features like inline data reduction and zero optimization don’t impact the test results. My question is: How important is it to customers that performance tests show the most strenuous performance scenario?
Here is a short independent blog by Crispyire called Everything is so... Xtrem that touches upon the same subject of testing.
Welcome everyone, this ATE discussion has began. Feel free to post your questions and our SMEs will be sure to answer them before the end of our event. Let's keep this discussion respectful and informative. Thanks!
How does XtremIO benefit non-production workloads – is it even worth it for them? Or should we only use for production?
I have seen that argument, but with the ability to create a virtually unlimited number of zero performance cost copies, with very little capacity overhead (at least if you delete them fairly quickly), makes XtremIO irresistible for making a test/dev farm.
My vote would be the inline compression. As a DBA you get immediate space savings somewhere in the range of 1.5 to 2 times. An Oracle database 2TB in size could compress down to 1TB. This means the DBA can fit more databases onto XtremIO.
The other part of the compression is with snapsots. Over time most snapshots have a data delta from the source which means they take up space. So compression offers an advantage here too because the data delta is compressed. This means more snapshots are possible.
Finally, this could save the customer money in that they don't have to purchase Advanced Compression.
