Poll: VMware vCenter Database Requirements and Issues
What Windows OS and database platform is your virtual infrastructure running on?
With over 20 database software platforms, numerous OSes, there is bound to be problems and incompatibility issues. I’ve had an opportunity to deal with one of those issues over the last few days. At one of my clients, vCenter 4.1 was running on Windows Server 2008 R2 with SQL Express edition, everything was working as it should until the VMware vCenter services started failing, vSphere client would not authenticate and log system admins into management console, so in other words, major problems as server provisioning and deployments were delayed!
