Hello, I'd like replicate a DBMS (PostgreSQL) under heavy OLTP workload with protocol C. By heavy I mean > 1500 transactions per second, which results in at least as many fsyncs. I've used DRBD a while, but in way smaller setups, where performance was secondary. The hardware I'm planing to run this on has not been delivered yet, so I can't just test it. My question now is whether (trunked) gigabit ethernet can delivery the short round trip times required for this application at all and if DRBD can use other transports such as Infiniband? Thanks! -- Regards, H.D.
