>From my experience that stuff is more relevant when you are worried
about performance on a physical server. I don't know much about how
vmware handles io distribution when a single VM is making requests to
separate disks, but I suspect that you would get slightly better
performance even in vmware when the db is in a different disk than the
logs.
In general I have had pretty rotten experiences with running a LDAP
server on a VM. I have noticed that the db tends to get corrupted (or
have problems with replication) when the server is running on a VM.
These problems tend to happen a lot less when stuffs running on a
physical server.
