Subject:	Notes on the meeting to prepare for CMS services


1. Jamie to get from CMS the latest list of services that they expect to be 
provided as a high priority 2. MoU list of services 3. Which SLAs do we need 
to generate - 4. What are the constraints on CMS
        e.g. Critical CMS services must be run on standard hardware, load-
balanced services.
             Only in exceptional cases can a stand-by machine be used - but 
this must be operated by CMS.
             Avoid complicated solutions that CERN will not understand.
5. Difficult services? 
    Phedex - databases - Oracle and MySQL?.
    Centralised services such as data location - Should look at an off-site 
replication.
6. MoU services
  (i) 1. Internal Networking - probably OK
      2. recording - needs the database and the castor piquet
      4. calibration, etc. brings in the need for infrastructure services 
including 
            -- LSF
            -- AFS -- main worry -- few experts, few failures, hard to fix
            -- mail                }  these services are essential and there 
is no piquet
            -- web services        }  although there could possibly be a 
piquet
  (ix) needs the grid piquet service - which needs PJASs and fellows 7. CMS 
should define people who can call out the piquet and escalate to call experts.
8. Tony to give a short statement on how CERN expects to run critical services
