We use keepalived for the cluster/LVS monitoring/management. We use SCP
to move the keepalived.conf file around to all the servers.
For content it is all stored on a Netfiler F720. The next upgrade will
replace the F720 with a cluster of Netfilers (F85C ??). The realservers
NFS mount the content (Webdirs, Maildir)

Currently SMTP,POP3,IMAP. We'll be adding HTTP, HTTPS & FTP in the next
few weeks. Our LVS is LVS-NAT, 2 directors, 4 real servers, Cisco 3548
switch.

I would like to see a Netfiler type appliance open sourced. I know I can
go with a linux box but I'm just not sure on the performance. I want a
fiber channel based NFS server will complete journaling, 30 second
reboots, fail over, snapshots. I think a linux box with EXT3 or ReiserFS
comes close but you don't get snapshots and I'm not sure how the failover
would work.
