Hi ARSListers, We are moving from all-custom applications on Solaris/Sybase/ARS 6.3 to a mix of custom applications and ITSM 7 on Windows Server/MS SQL/ARS 7.x.
We need to support 200-400 concurrent users, 75-150 of whom are using the WUT and the others on mid tier. Our Windows Server team would appreciate some real-world input on server sizing. I have searched the ARSList archives extensively (exhaustingly, if not necessarily exhaustively) and found relatively little guidance on this topic for current ARS versions. I did find a response from James McKenzie back in November '06 and one from Christopher Strauss in February '07 that shed some indirect light on the subject. Thanks gents for those. If you are running ARS 7.x on Windows servers, would you be so kind as to share your experience regarding the following? What is your user load & application mix? What hardware are you using (CPU type & count, clock speeds, RAM, etc.) for Windows servers, for which bits of the puzzle (ARS server, mid tier, database server). How are the bits combined on, or separated between, server hardware? Are you using load balancing hardware/software? If so, what/where? What typical and peak-load response time,s or other performance metrics, do you observe (WUT vs. mid tier)? Thanks for any clues, Doug Anderson Mayo Clinic Rochester, MN _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org ARSlist:"Where the Answers Are"
