Hello,

Can I install HA-lizard in two servers connected by a WAN (MPLS) ??

I know that the problem is the latency and not the bandwidth. But maybe is possible ?

Our requirement is "simples": We need replicate the data from 3 VMs (less than 300K/s) from one server to another remote using our WAN. And in case of emergency, start the second server "manually" (is not necessary be automatic).

I know that it is more a DR than a HA... But, ha-lizard look very well.

commentaries ???

Ha-lizard relies on DRBD for replication. Technically, it may work fine for you given the size of your dataset. I am fairly certain that drbd had a commercial version specifically intended for higher latency narrow bandwidth situations. Also, as an aside, ha-lizard requires that the replication interfaces be on the same subnet.
