Experiences at RUM
- Applications and development tools are widely and freely available
- Powerful servers with APIs to almost anything
- Our experience:
Linux + Apache + Mysql + PHP3/4/5 =
Powerful and free Intranet/Internet platform
- Samba
- Linux can replace windows NT to control domains (PDC).
- Used to provide file and print services.
- Web Administration Tool (Swat) available
- Easier local and remote administration.
- Better performance:
- SMP
- 2.0.0 had poor SMP support (First stable kernel series with SMP support)
- SMP needs applications which use SMP capabilities
- Quad SMP on Primergy seems to work with a noticable stabiltity
- High availabilty (Uptimes of 100 days and more)
- HPC programing environment freely available
- Interconnect hardware support available
- Diskless configurations stable and ease administration
- Highly scalable: add or remove nodes whenever necessary
SAP R/3 in Mannheim
- 1998: SAP R/3 (IDES) on RM1000
- 1999: SAP R/3 on Primergy 870 running Linux
- 2004: SAP R/3 service terminated due to budgets cuts
