I can see someone reading this thread and tossing two crappy Ethernet cards in a box and then complaining it doesn't work well. It would be more than welcome indeed..! I have the feeling that HAST isn't that much used (but maybe I am wrong) and it's difficult to find informations on it's reliability and concrete long-term use cases... Also the pros vs cons of HAST vs iSCSI > > Perhaps those doing this could listed recommended NICs so write performance of the slave over the network isn't slow as sin, or their relevant part of their config scripts to get this running well, any sysctl's set to boost performance, gotcha's you e seen using this setup, and if a mirror failed were you happy with this. India during recovery?
