Multiple Server Network Setup

Hello Fellow Experts,

We have a question regarding the most effective and secure way to setup a cluster of web servers.

At the moment we have:
1 x Load balancer
3 x Web Servers
2 x Database Servers

All 5 servers are running citrix xenserver advanced for high availability and an extra NIC dedicated for remote management.

Our throughts were:
Load balancer is connected to the internet
3 web servers are connected to the load balancer
2 database servers are connected to the web server
ALL 5 servers are also connected to the internet via extra NIC for remote management and Xenserver management.

Does the above setup seem logical and if so does this mean we would need to setup a switch to host an internal network between the 3 webservers and 2 database servers?

Thanks

I'd disable these connections

How would we remotely reboot a machine without needing to physically run down to the datacenter?

better to use a vpn for the management.

Thanks to everyone for responding. Just to recap the suggested network setup is:

1) 2 X load balancers (setup in HA config)
2) The load balancers connect to a switch that creates a VLAN and manages VPN connections for remote server management
3) The switch connects to the 5 servers using the main lan port each server to have a firewall configured to accept connections from dedicated VLAN IP's only
4) The switch connects to the 5 servers using the secondary land port, and manages the VPN connections for remote XenServer management.
5) The switch also connects to the the Dell DRAC ports and manages the VPN connections for remote server management.

To add some additional information we are using Dell r610 servers and a Citrix Netscale load balancer.

Thanks
