Enterprise Email Infrastructure
Our Enterprise class email server systems offers
highly scalable, fault tolerant, superior performance
and reliability in a multi-server environment.
All of SAV25's email solutions employs MailEnable's
extremely flexible, robust and reliable email platform.
Our DNS, Failover , Backup and Network security
system can be easily integrated with Mailenable to
provide a complete and robust email infrastructure.
Select the Email Infrastructure for your business:
| 1. | Redundancy Clustering |
| 2. | Distributed Services |
| 3. | Scalability Clustering |
System Requirements
Clustering may be implemented to introduce redundancy into the system; with the objective of mitigating the risk of system failure or reducing downtime.
In our example setup above, load balancing for the incoming email is managed by the advanced round-robin and failover system of Simple DNS and Failover. The Public IP addresses used by the mail server are distributed on the clustered Smoothwall Firewall.
We have two mail servers configured to access a shared redundant disk or network attached storage (NAS).
A clustered IP address is provided for the front-end interface to the mail servers. Mail clients are configured to connect to the clustered IP address of the server. Simple DNS and Failover also used for load balancing of connection of mail clients.

| 1. | At least 2 Mail Enable Servers |
| 2. | Simple DNS and Simple Failover Servers (2 sets recommended) |
| 3. | Smoothwall Firewall with Failover (3rd party Firewall with the same features may also be used for the system) |
| 4. | Storage Server (EONSTOR DS or ESVA from Infortrend recommended) |
| 5. | Novabackup as backup and disaster recovery recommended. File Replication PRO may also be used for real time file synchronization. |
In some cases, it may be desirable to distribute functions across multiple servers. For example, it may be necessary to have a web server providing web mail functions only (with a back-end sever providing back-end messaging functions).
The example above is recommended if email clients relies heavily on the webmail and specially if web collaboration is used extensively by the users.
The SMTP and other services provided by the Back end MailEnable.
For networks with extremely large volume of users and requires that the email system be able to handle additional email users at anytime, our Scalability Clustering solutions is recommended .
A separate server can be configured to share the same message store and configuration data. This allows organizations to configure separate servers to act as front-end servers, leaving the message store and configuration on an alternate server. This approach means new servers can be added to the environment to accommodate load.
This is particularly relevant if using antivirus or content filtering, since these services can be resource intensive.
In the above example, multiple front-end servers are clustered to a shared backend storage server. The storage server is configured with a high performance disk array to provide effective throughput to the front-end servers. It is also important that the network throughput is adequate to service the requests of the front-end servers.
