1. HELIX Project (Hp Eradication - LInuX integration) A project in SL, ST, IT and PS

2. What is HELIX? SL project to replace WS  ST project –Replace old expensive HP servers with new cheap linux servers File servers Data servers (TDS) Application servers….perhaps not yet… –Use IT CERN wide services as far as possible purchase, installation, configuration, maintenance,...

3. Existing Hardware SL and ST PCRSRV1 & PCRSRV9 each consist of : - HP K-Class Server 3 CPU PA-Risk 8200 cost: 60,000CHF - Eurologic El-RAID 300 20GB user space cost: 38,000CHF

4. IT File Server (pcrsrv1 ?) Experimental file server comprising : – Elonex 24-bay cabinet – Floppy + CDROM – Linux system disk + mirror disk – 2 sets 10 x 75GB IBM disks (RAID mirrored) – 1.5TBytes < 30,000CHF

5. IT LINUX Farm (pcrsrv9 ?)

6. Data Servers (TDS) The third TDS server (for ENS) machine is a PC running linux. There is a spare linux machine as backup.

7. Application servers Now running applications for –ST/AA - FactoryLink or DVtools access –ST/CV - UMMI (DV) supervision –ST/EL - UMMI (DV) until ENS ready –ST/MO - UMMI (DV) supervision –TIS - UMMI and LabView A LOT OF SOFTWARE ON HP!!!!

8. What’s next? ST involved in project from the start! –We have many many HP applications and we depend on SL services. User requirements phase –Each group will be consulted during UR phase –At first glance, we phase out rather than port sw Don’t panic (yet). – But don’t buy any more HP hardware without consulting the Helix project team

9. Conclusion Should be a divisional project –Great impact on operation in many ST groups –Need for divisional strategy for the future (ST CSWG) –Man power for SW porting and new hardware cost should not be underestimated
