Microsoft SQL will be 1 of the key component, and you will require to plan for the high availability architecture to support the production environment.

The best approach may just consider to build an independent Active/Passive or Active/Active SQL cluster to support the infrastructure. A backup for the SQL is always recommended to create recovery point in the event of data corruption. Most data on the SQL databases is the configuration changes, log and etc. Similar to VMWare vCenter Database.

Many of you may trying to upgrade the Virtual Center Server 2.5 U3 which recently release from VMware. As usual, I always like to be the earlier bird to test out everything and be excited to implement to my environment. Here is what I discover during the after the upgrade.
