We have a PeopleSoft ERP installation with two web servers. Our networking department purchased a 3750e switch as we wanted to load balance the two web servers.
However, I don't think we are getting what we need from the current configuration.
Ideally, I want a "virtual" IP that is translated at the switch to either web server 1 or 2 based on load and availability. However, I'm being told that the 3750e can not have a virtual IP.
Instead, DNS returns two IPs when I connect to erp.company.com. The client then picks once of these IPs and sends the request. The switch then supposedly routes this physical IP to one of the servers as needed. In other words, if server 1 has IP 22.214.171.124 and server 2 is 126.96.36.199, the switch may route traffic to 188.8.131.52, even if the client request 184.108.40.206.
This just doesn't sound right to me.
Any suggestions on how to properly configure a load balancing/failover configuration with one 3750e switch and two web servers?
