A major consideration for the design of the customer’s infrastructure is whether or not the customer is willing to virtualize some of the ZENworks Configuration Management infrastructure components. With version 10.2, the components are supported on both VMware and Xen. This could be an excellent low-cost alternative to hosting more ZENworks Configuration Management servers on fewer physical servers.
For example, if the customer needs to deploy three physical servers in the data center, it might be possible to increase this number to two or three hosted virtual servers on two physical servers. This would create additional fault tolerance and redundancy, as well as better performance across the board.
NOTE:For optimal performance of the Primary Servers running on VMware ESX, set the reserved memory size to the size of the guest operating system memory. For more information, see TID 7005382 in Novell Support Knowledgebase.
