Purchased the licenses and services on Infrastructure with 2 servers, use external storage as shared storage, Red Hat Cluster Suite enabled for fail-over cluster, iRedMail and iRedAdmin-Pro with 64 bit environment on the project.

Purchased remote installation and cluster setup support from iRedMail team, thanks ZhangHuangbin for the setup, configuration , performance tuning and complete the tasks with a very tight schedule.

Performance fine tuning is required and the services are running smooth.

Hardware information for your reference:
- 2 Servers with Quad Core and 12G ram per-machine.
- External storage as shared storage for cluster environment (Recommended DAS, ISCSI SAN or FC SAN)
