I have no opinion on the subject, but for others who haven't read the
article the 10gbe referred to is to keep the server in sync with a
backup server somewhere presumed in the same room. As such 10gbe seems
reasonable and inexpensive (newer supermicro can come with them built-in
and standalone cards are reasonably inexpensive. The new Netgear 10gbe
switch is even quite affordable)
As near as I can tell they advocate putting all the storage on the host
machine and using network to sync off the machine (vs SAN where all the
storage is off machine)
I don't really get where they are going with this solution though?
