One of the things that amazes me about Oracle is how active its staff and product groups are in their blogs. In addition to all the traditional technical resources available through the product marketing and support channels, engineers and product managers maintain some amazingly active blogs where they post regularly about:

He spends a lot of time operating Oracle Solaris Engineering's OpenStack cloud and is coauthor of the OpenSolaris Bible (Wiley, 2009).
Needless to say, he knows his stuff.
Earlier this month, he posted about troubleshooting I/O loads in an Oracle Solaris OpenStack Cloud environment that I wanted to highlight by turning it into an official OTN community article here on community.oracle.com.

It was easy to rule out CPU load on the compute nodes, as prstat quickly showed me that load averages were not at all high on the compute nodes hosting my guests....[Click Here to Read More]"
