We're running our cell (5 db, 12 fileserver, rw +ro ) as VMs exept one
db server which is on a separate location where we couldn't get our
hands on an ESX server yet. The vice partitions are raw disk mappings
from our SAN.
AFS is the filesystem for almost all our web and typo3 servers. Each
server is hosting a couple of apache instances (20-30) which are running
with different tokens to isolate the processes (wrapped with kauth and
srvtab). We don't see any performance issues.
