More HA nodes

Hi all,

currently I found that only two HA nodes can be deployed (Master & Slave). Can I add in future another (third) node to became secondary Slave?
I would like to have 5 - 10 1U Cluster W2008R2 machines and 3 storages with MPIO to have better redundancy and performance.

Hi Petr,
Actually, StarWind HA is based on 2 nodes only. In future versions (probably autumn 2011) we will introduce the possibility of adding a third node to perform remote replication of the HA.

Thanks for reply. Will be adding third node available online or just destroy HA and create tripple HA?

"Master" and "Slave" are wrong words actually... Both nodes are equal. We have active-active rather then active-passive architecture.

We'll offer limited-time free upgrade for triple-node config. Just power third node and re-initiate sync with it. And yes you're correct. More nodes means better uptime and higher performance.
