Thats a very "rough" estimate (and only for the WebUI). Hardware requirements depend on usage patterns in a *huge* way, we also have customer installations which host 500 WebUI users on a 1 GB dual CPU system. Anyway, resource usage has little to do with the snsd. The snsd is mainly for providing concurrency by dispatching requests to various instances, I think there is a picture in the SKYRiX 4.1 admin guide. > I was wondering if anyone can confirm this or if anyone is running OGo or > even Skyrix in a much bigger environment (let's say... more than 1000 > users). We are currently working with a customer who intends to deploy SKYRiX to about 5000 users. AFAIK this is planned to start out using four application server nodes and a storage server. Maybe we can make a success-story if the system is finally implemented ;-) > I'm very unfamiliar with the architecture of OGo, but does anyone here > have any idea if it's possible to use it together with Linux HA and load > balancing tools (LVS, drdb, heartbeat, etc)? I would be really interested in > hearing about this. Thats a very broad question as OGo is composed from a lot of different components. Eg ZideStore is very easy to cluster given that it is a stateless daemon (though routing based on the HTTP user will give a speed boost) and WebUI is a bit more difficult since session information needs to be retained (this is what snsd does). But I would really like to see some people write some howto/details on how to setup various HA configuration (eg on docs.opengroupware.org). regards, Helge -- http://www.opengroupware.org/ -- OpenGroupware.org Discussion [email protected] http://mail.opengroupware.org/mailman/listinfo/discuss
