To Size Your Multiplexing Services

When you size your MMP and MEM, the calculation is based on your system load, particularly the number of POP and IMAP concurrent connections for the MMP and the number of HTTP connections for the MEM.

These instructions assume that you are installing the MEM and the MMP on the same machine.

In addition, you must:

Steps

1. Add CPU or a hardware accelerator for SSL on MMP and MEM if appropriate.

2. Add memory to the machine if the MEM is being configured on it.

3. Add more disks for an SMTP proxy for the MMP.

4. Account for denial of service.

5. Add capacity for load balancing and redundancy, if appropriate.

   As with inbound MTA routers, one or more of each type of machine should still handle peak load without a substantial impact to throughput or response time when you plan for redundancy in your deployment.
