can we configure a Red Hat Linux server with mail server,file server and web server simultaniously. If yes will it be successful for 100% utilization for ON -Line purpouse

Yes you can.
However, if you need high availability, you should take care about building your sytem redundantly - e.g. use some sort of RAID for disks, have spare parts such as disks, power supply etc. at hand. And don't forget about UPS.

Also check what would be load on the system.

If the load is high it is always advisable to split the services on different servers for high performance and reliability ... Say if the services are on diff servers then if mail server goes down you still have the web server and file server running and same for all the other cases.

This way you can ensure better relaibility and uptime to your users

And you can have on one machine the backup servers of the other... that way, if your main mailserver goes down, you'll still get all your e-mail to your backup server and don't lose any important e-mail you may get.

Point taken.

If you need to speak on more reliability then you can use hardware load balancers to balance load for servers like webservers, Using raid on servers to prevent data loss against single disk failures and a whole lot of more options ... Its just how much money you wanna put in and how much uptime you need to put forward :study:

yes, you can
