Sun Java Communications Suite 5 Deployment Planning Guide

MMP and High Availability

Never deploy the MMP under HA control. An individual MMP has no static data. In a highly available environment, add one or more additional MMP machines so that if one or more are down there is still sufficient capacity for the peak load. If you are using Sun Fire BladeTM Server hardware, take into account the possibility that an entire Blade rack unit can go down and plan for the appropriate redundancy.
