May 10th, 2012 Alex Gorbachev No comments
When preparing for the the IOUG Collaborate 12 deep dive on deploying Oracle Databases for high Availability, I wanted to provide some feedback on what hardware components are failing most frequently and which ones are less frequently.

Oracle Database Appliance — Storage expansion with NFS (dNFS, HCC)
