Those who have been architecting vCloud Director environments from the early days know that this has always been a pain point. I personally have had many discussions with product management and engineering to get support for database clustering like Oracle RAC or Microsoft clustering services for MS SQL. Unfortunately neither 1.0 and 1.5 supported it. So the big questions always was, when will database clustering support for vCloud Director be added?
I had a couple of discussions around this again last week and noticed it was still not listed until someone pointed me to the vCAT 3.0 documents. Hidden on page 110 of document “3a Architecting a VMware vCloud.pdf” I found the following statement:
VMware vCloud component database resiliency is provided through database clustering. Microsoft Cluster Service for SQL and Oracle RAC are supported.
Yes I do realize that this is not a KB article, or even mentioned in the vCloud Director documentation. I have requested the docs to be revised and a KB to be created. Hopefully those will follow soon, for now this statement is all we needed! When the docs are revised or a KB is published I will add the references to this article.
