[IMail Forum] Service Survery

[Halstead, Ronald -CONT(CSC)]

I work for the Navy.  I'm currently developing a new Training Network with Windows 2003 Server.  I would like to setup Imail for approximately 50 thousand users.  I was wondering:  How many servers do you suggest for this amount of users? How many processors per server? How much RAM per server? How many simultaneous connections per server can I expect? If any of you have setup clustering and have any hints, tips, or known issues I may have?   A little background, I am currently using:  Dell Poweredge 2650 Dual P4 Xeon 2.8 GHz 2GB Ram 3x32GB SCSI Drives     Any help with this matter would be greatly appreciated.   Thanks, Ronald Halstead Jr. Systems Integrator - CSC NETPDTC Pensacola Comm:  850-452-1001 x1271 DSN:    850-922-1001 x1271
