You also want to consider the more applications/processes you run the more likely one of them will stop working. This translates into downtime. If for some reason your GC stops replicating or answering requests and the normal recovery steps don't work, you may have to reboot. It is the same for any additional processes you run on any one machine.
To summarize: Reasons not to have and exchange and a GC on the same machine 1. Added troubleshooting complexity 2. Added DR complexity 3. Added CPU load 4. Added network load 5. Added disk I/O 6. Added hot-fix and SP complexity (dealing with interactions of hotfixes) 7.

And I have some open question where I need more a real life answers than MS-white papers. At first I will create own AD site for Exchange 2000, so users logons will go other sites. Also I thought to install GCs on the same servers than Exchanges are. I haven't seen any good answers we should I not to do this. Backup/recovery might be one and if I have problems with GC, but still... But if I use GCs on the same server, then I might have better performance from GC, less users and only one Exchange per GC. Maybe I need one server more to decrease user counts on one server, but it should not be so big. So I don't need so much hardware. And now it is very easy to dedicate one GC per one Exchange 2000 servers. If I use separated GC servers: MS recommends using one CPU in GC against four Exchange servers, which have one CPU. This sounds like no matter how many users we will have in Exchange servers ? If I have eight servers where are 10 users in each one. Do I still need two GC servers (assuming that servers are one CPU servers). Is here anyone who have more than ~3500 users per server which is not clustered ? May I hear any comments from you, how it really works ? How often you are rebooting your servers or unmounting databases ? Was it SLA your only argument when you planned storage groups and databases ? best regards .-Pepi-. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:leave-exchange@;ls.swynk.com Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:leave-exchange@;ls.swynk.com Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:leave-exchange@;ls.swynk.com Exchange List admin: [EMAIL PROTECTED]
