It's not much different from having all three on the same server; you'll want to keep backups and all the usual stuff. It's complicated a bit by the size of the IMDC & Flows databases, but conceptually it's the same problem. The only thing that's unique to this situation is the possibility of using the other machines as spares. I don't know offhand whether you need additional licenses for this, but in theory you could have IM installed on all three servers. If the dedicated IM machine ever went down, you'd then have two standbys. Unfortunately the process of keeping the spares in sync is a bit clumsy; you can do it by copying files or via IM's HTTP API. Either way it's an incomplete sync, and there are some hiccups to getting the database to recognize that it's really the same IM server reporting, just from a different IP. With some work you can get a basic standby setup, and we have customers who do that, but there's a lot we still need to do on our end before that's an officially-supported path. dstempien wrote: > what front-ends they are using or have developed for referencing and > reporting on their data? I don't have a complete picture, since I hear mainly from people who have encountered some problem or want things to work differently. IMDC of course includes its own front-end, Reports, that many people use. It's not at the point where it can replace a real reporting dashboard, but we're adding to it in every release. Aside from that there are some people using Crystal Reports, and several have custom interfaces; scripts that connect directly to the database. In terms of what people query, that varies a lot depending on the kinds of devices they're probing. Events - when devices go down or otherwise change state - are probably the most common target, since IM on its own keeps no history of those changes. The built-in Reports front-end, especially with the new datasets we added in 5.5, works pretty well for that.
