Ok, that sounds more reasonable.

Yet a better idea is to check now on a testmachine if it works correctly
for you. But I guess you want to run some jfs and ext2 on the servers,
don't you? Just try it out before you switch to 2.2. However I really
recommend you to use the 2.4.x kernel series for a webserver and TUX 2.0
and maybe the newest released zerocopy patches, they are included now in
the ac-tree. For the LVS I recommend the 2.2.x kernel with the 1.0.5 patch.

Last two questions before I will send you the network I have in mind
o Where are the webservers?
o What is the VFS and what is its purpose?

> VFS1 is the virtual file server
I hope you don't mean the LVS.

Great, so far so good ...

I think you won't need this.
