In our data center we have a number of web server farms. They are configured as they are - but i (the new network guy) am not totally comfortable with their security and design.
Basically the servers have 4 NICs. two sets of two. each set of two is teamed. One team is internet facing with a firewall in Situ (am good with this). The other team is facing the backend network (DB servers, management network etc...)
There are switchs that connect the from team to the Firewall and these in turn connect back to the Backend switches. with no intervlan routing. I think just for fault tolerence.
i am basically asking for any tried and tested /proven webserver network design incorporating security, performance, functionality and redundancy.
Hope you can help
