Using BE-CO Frameworks

7. CMW project Mandate & Scope
Standard set of MW solutions
Centrally managed services
Track & optimize runtime parameters
Well defined feedback channel for users
Provide support & follow-up issues
Scope: CERN Accelerator Complex
Operational 24*7*365
Must be Reliable & High Quality
In all Eqp. groups (3 dpts: BE, EN, TE)

8. CMW in the Controls System

9. Middleware Infrastructure in numbers
4’000 CMW Servers (processes)
85’000 Devices => 2’000’000 Properties (i.e. IO points)
24 Proxies (10 Injectors, 14 LHC)
20 JMS Brokers (10 single Brokers, 5 HA Clusters)
15 DIP Gateways
2 RBAC A1 Servers
2 Directory Servers
1 Configuration Server
1 Log Converter & DB Writer
JMS:
Print as money :
~3200 times the LHC
Next : No of brokers.
CMW Proxies :
gained popularity as they run stable
