Hello.
We don’t have minimum HW configuration defined, as it depends on minimum SW you need (
http://devnet.kentico.com/docs/devguide/system_requirements.htm). Anyway, recommended HW depends on particular project, its size and nature. We have some performance reports so you can see them on
http://devnet.kentico.com/Blogs/Martin-Hejtmanek/July-2010/Kentico-CMS-5-5-Performance-report.aspx. It also contains server hardware configurations we used, so you can compare it with yours.
Just a few notes to your configuration:
RAM is 1 GB – In general, 1GB is total minimum. You should consider having 4GB at least.
ASP .net version 1.1.4322 – you need at least .NET 2.0. Beggining upcoming version (Kentico CMS 6), you will at least .NET 3.5
Total size of Hard disk is 20 GB(single drive) – this is enough for web project itself.
SQL Server is Microsoft SQL Server 2000 - 8.00.194 (Intel X86) (Build 3790: Service Pack 2) – SQL Server 2000 is not supported. You need SQL Server 2005 at least.
As for IIS – I am not aware of any significant impact it could have.
As for the same DB for staging and production – yes, it is possible.
Best Regards,
Radek Macalik
