I did a similar post last year and in trying to start a bit of a tradition looked at the same statistics again this year. And the result was quite a surprise. While I thought that 2013 was the year of the 12c database it actually was still the year of the infrastructure. At least here at this blog.
2013 has been an awesome ride for me and did not leave much more to wish for. I was able to attend and speak at a number of conferences and user group meetings around the world: IOUG Collaborate in Denver, OUGN vårseminar on a boat from Oslo to Kiel, OUG Scotland in Edinburgh, Oracle OpenWorld in San Francisco, the OTN APAC tour in Auckland and INSYNC in Perth, DOAG in Nuremberg and UKOUG in Manchester. I was awarded ACE Directorship and was elected vice president of the RAC special interest group. How much better could it get?
Anyway, these are the most accessed blog posts of 2013:
3rd place: ASM vs ZFS vs UFS performance comparison
This was a good, quick and fun post where I quickly setup SLOB with three different ways to connect the same storage array. The result back then was that ASM performed way (about twice) better than ZFS and UFS. But I when I recently thought about my results I may have forgotten to make sure the filesystems were properly aligned with the block size of the storage. If that was truly the case it would explain the siginificant drop in performance. Will have to go back to the same setup and re-test.
This is a rather old post and was the winner of the previous year. Still a surprise to me that this quick and dirty hack with a lab server seems to be so interesting to so many. I will take the opportunity to revisit the post and check if there are things to add and also if AI is more cooperative with this setup these days. And maybe even file an RFE if I am in a really good mood.
Really, this is just a testament to the poor ecosystem of supporting software around Oracle VM. As this product is evolving to become better and better, customers are still trying to figure out how to take backups of their machines. The good news is that Oracle came up with a whitepaper describing Oracle VM Backup Best Practices for everything from OVM Servers and the Manager to guests. But still missing is a backup product that orchestrates all this without customers having to build this themselves.
