Hi, technically it is possible. However you should count with extra RAM taken by Flow Storage (up to 80% by default), so your SQL can possibly loss some of its performance. Also put Flow Storage on different disk than SQLDB. So to answer the question - possible but not recommended.
Thanks, this is helpful, and what I had expected to hear.
If I may, let me ask another question. My current Poller and SQL servers are located in one of my branch offices and scheduled to be moved to our nearby data center in Q1 2014. Could I spin up a Flow Storage server in the data center now and access it over the WAN? This would just be temporary for up to three months until I can coordiante bringing the Poller and SQL servers over, then they would all be on the same local LAN segment. Bandwidth is not a concern, and I would expect the latency between the Poller and Flow Storage server to be in the range of 10 - 15 ms.
Just make sure those two machines see themselves on TCP 17777 port (+ SQL server on TCP 1433). Such latency should be ok. Bandwidth required should be averaging around 5 Mbps, with bigger spikes each minute.
