Quick Failover & Scalability questions
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]
The simplest would be for the clients to reconnect to the new server and re-establish communications. However, how painful would it be for the new server to keep the same sockets open for a truly seamless failover? Again, I am only concerned about the tgtd internal states at this point - assume that the block device mirroring as well as the keepalived/heartbeat/iptables/fencing/etc issues are handled already (though there would obviously be a good bit of integration work there!).
My 2nd question - I am starting to play with things like ionice and scalability. One critical aspect of scalability is limiting the first connection's performance so it doesn't degrade so quickly as more clients come online. It appears that ionice will probably not have the features I need; is this on the tgtd roadmap? Even something as basic as a generic "io operations per second" would be a good start.
