Determine if Virtualization is to be Used
Will SiteMinder be implemented to a virtual environment?
Consider the following before implementing SiteMinder to a virtual environment:
- Be sure to review the CA policy on virtualization.
- Be sure to:
- Be sure to size the CPU, disk space, and memory available to the virtual environment. Use the system requirements detailed in each SiteMinder installation guide to determine how many components to deploy to the entire system.
- Be aware of issues associated with clock synchronization and multiple operating systems. Unsynchronized clocks can result in unexpected SiteMinder behavior.
- When considering where to deploy components:
- We recommend deploying Policy Servers to the virtual environment. We recommend that Policy Servers have their own Ethernet port. A dedicated port helps to prevent SiteMinder from missing requests because it is competing with other virtual hosts for available bandwidth.
- We recommend deploying Web Agents to virtualized web servers.
- We recommend deploying all SiteMinder data stores to physical hardware and operating systems. Directory servers and databases can become very resource dependent. If deployed to the virtualized environment, this dependency can result in performance degradation.
