I'm looking to create a multi-server environment for metastorm.  The total setup will include...

1 virtual server for a test environment(test sql database housed on sql cluster)

2 virtual servers running engine/web(each) for redundancy/load balancing
Live database housed on sql cluster.

I'm running v9.1, Is there a good guide to follow to set these up?  Is there a standard database naming convention that would make this easier for metastorm to support in the future if a major problem occurs that cannot be fixed in house?

That is the same configuration we've been running on V6/7 for years, and are running on V9 now, without issue.

1 SQL Server database
2 virtual engine/web servers installing normally.  Our configuration files use the local engine.
1 load balancer configured to load balance between the 2 engine/web machines

We still use "ework" as our database name, but that is for simplicity.  Since we've been using BPM the name of the product went from e-Work to Metastorm and now OpenText.  Pick a name that works for you as its name doesn't really matter as long as you configure your connections correctly.

I won't be using a hardware load balancer.  Looking to load balance using software.  I've seen some tidbits in the architecture guide, but it doesn't seem to go very in depth unless it's really as simple as just mirroring the config files.

Has anyone tried putting 2 metastorm servers in a cluster using the built in NLB on server 2008?

So i was able to get this completed by using DNS "Round Robin" to both servers which are setup exactly the same.  Both have IIS and Engine running on them.  Configuration wasn't very hard at all, though I'm not a fan of metastorms updates that knock out all custom configurations each time you do an update.

Agreed 110% especially setting like SSO configured per their specifications.  This will mean a longer "hard down time" to upgrade in the future and a possible chance of missing something ... though we have created a check list to minimize this possibility.

I think they should only change those particular settings (e.g. individual web.config settings) instead of replacing the whole file.  It used to [generally anyway] work this way in V7.  And to rebuild the web site every single time breaking IIS settings <sigh>.

The environment i just setup minimizes this "hard down time" significantly.  By using round robin DNS, i can just change the DNS to point to only 1 server and change the engine config to only use one server.  I can then update the other server, change over to that server in DNS/config, update the other one, then the only downtime to occur would be setting the engine config's to load balance again.  soo if everything goes well(yeah right), i should only be down for 5 minutes tops
