Joe's commets mirror my experience, but with large database and log files. 2GB+ minimums.
64 bit OS do not seem to yield positive results with remedy. Unix/Linux does seem to process, scale, or respond better, if you can support them. Ensuring the database has enough RAM is critical. More so, is that the physical database design does not have any bottlenects. At one place I worked, all the databased had a shared filesystem and it eventually crippled the systems during backups. Ars Server memory usage is also impacted by the number of fast, list and private threads you run. Read how this memory allocation is determined and account for it in you memory calculations. Modern virtual environments require *More* resources but provide some amazing options. You can spread AIE load over non-remedy servers, if that helps, to manage resources better.

Urgent ** With that kind of configuration I would go with at least 3 servers in a server group - considering you have at least 300+ concurrent users. Each single instance with at least 4 GB RAM, an initial data file size of at least 1 GB and a log size of about the same.. With that being said, your site is a better candidate for a UNIX operating system instead of Windows. When it comes to large volume users and high volume transactions, I'm not quite that confident about Windows.. There may be a few who would disagree with me as yes there are sites out there handling pretty high transaction volumes on Windows using MS-SQL. If you are having virtualized environment, I'd like to warn you about performance issues I have faced on VMWare where the instances didn't get the necessary horse power needed to run the applications (almost a similar environment like you mention).. And recently have considered standalone servers instead of virtual servers running on VMWare.. Hope this helps... Joe PS: In actual practice the minimum recommended RAM for the AR Server and apps seldom work and maybe ok for demo environments.. go almost double the documented recommendations.. -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[EMAIL PROTECTED] Behalf Of Naveen Kaushik Sent: Sunday, January 06, 2008 11:49 PM To: arslist@ARSLIST.ORG Subject: Server Sizing Guidance ... Urgent Importance: High ** Hi Lists, I need an urgent help regarding remedy server’s sizing. We need to implement IM, PM, CM and SLM modules and there are significant customizations in IM and CM modules. Along with that the CMDB will be significantly customized to cater to above four modules. Also the AIE integration with CMDB to populate it from 3 to 5 discovery tools and ARDBC integration with AD are in scope. Also 300+ Concurrent users will be using the ITSM modules on first go live. The environment is Windows 2003 EE SP 2, SQL Server 2005 EE, ITSM 7.0.2 and CMDB 2.1. I am urgently looking for a document/theory/calculation matrix which can guide me to give the hardware requirements (Most Significant is PRIMARY MEMORY) for a QA and Production Server on Virtualized environment. There will be 6 boxes on a big virtualized box and there will be three pair that will act as Database, Web and Application server for QA and Production environment. The knowledge I have is: RAM :- 2 GB for AR Server + 1 GB for Mid-tier + 2 GB for each Major ITSM module (from ARS Docs), but I need plenty of FACTS and INFORMATION to give a concrete base for asking the Hardware which can cater my requirements and satisfy a really tough customer. After all my searches now I rely on the vast experience of this list to give some pointers or some guide. Please help!
