[Gluster-users] Server side or client side AFR

[roberto freguia]

Hi, I think that to use the server side AFR is more correct put in front
of a server gluster an LVS Machine (Linux Virtual Server) to balance the
client load, or use, on all AFR server, a protocol like carp (UCARP)
that expose a single IP address for gluster all servers, so the client
will always be connected to the server online.
