I am in the process of researching migration from windows serves to 
Linux. Currently my windows servers use DFS. I want to know if the 
following will work.

2 replicating failover AFS servers
10 Fedora Core - AFS Client - web servers

I would also like to make the AFS servers double as virtualization 
servers for low traffic network services like mail, ftp and low traffic 
webs. The remaining 10 web servers would get their web files and 
Tomcat/Apache/Java installations from the pair of AFS servers.

The web applications are caching so once a disk file is read in it is 
cached until the application is restarted. This should help reduce the 
network traffic.

All servers would have bonded GIG ethernet.

I am planning my AFS servers to use the following hardware
Dual Core AMD Opteron 2216, 2x1MB Cache, 2.4 GHz, 1 GHz HyperTransport
8 GIG memory
Dual GIG Ethernet NICs

My question is this...can AFS and Xen coexist on the same machine well?
