After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 2 Overview  Background  New system study  Final solution  Plan

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 3 EDMS Service  Engineering Data Management Service  It provides the necessary tools and the support for the creation and implementation of the Quality Assurance Plans needed to LHC machine and experiments  In the near future: it will have a larger scope as a data management system

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 5 Current EDMS Cluster  DEC based cluster (AS4100+DS20)  Storage (HSZ70, 80GB mirrored)  Mix of home-made and vendor applications  Data under Oracle (2-node SUN Cluster, 18GB)  Shared responsibility amongst  EST/ISS  IT/ PS  IT/ DB

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 8 Reasons for the migration  HP/Compaq/Digital architecture will not be supported by IT in the future  Increase in the use of Oracle based tools (ie iAS and https support, MP5)  General system performance improvement  Centralization and rationalization of EDMS service

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 9 Possible Solutions  Two 2-node clusters Current central database cluster + a new EDMS cluster  One 3-node cluster Merge of current central database cluster and a new EDMS cluster

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 10 Solutions Pro-Cons  Two 2–node clusters  Cheaper purchase of a new EDMS cluster  Simpler migration  High-Maintenance cost over the next years  Overload in the cluster administration  One 3-node cluster  Enhance EDMS db performance and integration  Cheaper maintenance cost  Single cluster administration  More expansive purchase of new EDMS cluster  More complex migration

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 11 Solution: one 3-node cluster

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 12 New EDMS Service Infrastructure  Nodes: 3 SUN V880 with 2 UltraSparc III CPUs at 750 MHz, 4GB memory, 6 internal disks  Storage: 2 SUN T3 WorkGroup with 324 GB mirrored  Interconnections:  2 Qlogic FiberChannel 8- port Switches (for T3WG)  2 Gbit Ethernet Switches (for the private network)  Public Network:  on Gbit Ethernet

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 13 Advantages  Integration: EDMS service + Database services  High-Availability  Administration: 1 cluster instead of 2 clusters + OEM  Scalability: possible to add 1 node  Performance: database and networking  Storage: more space  Costs (see next slide)  Test Platform: the old current Public database cluster  Expertise: SUN Solaris + 2- node cluster

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 16 So far …  Hardware is installed and tested  A first SUN cluster software installation is available for testing:  Fail-over mechanisms  Coexistence of HA services and OPS (Oracle Parallel Service)  Stability

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 18 Experience  Some issues related to SUN certification of the requested configuration  Eventually we are satisfied of the outcome and SUN support  Tests run so far are satisfactory, but coexistence amongst different services requires more work and understanding  Other service might be included

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 19 Migration Plan (1/2) Cluster installation and certification Mainly SUN1 week Software Installation + Porting of existing services + High- Availability tests IT/DB (with IT/PS collaboration) 2 months Database migrationIT/DB1 month Application Server migrationIT/DB1 month

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 21 Responsibilities Currently (until migration is completed)  IT/PS: Hardware + OS + Cluster + CADIM + File Server + License Server + correspondent data safety  IT/DB: EDMS database and related application server + Oracle data safety  EST/ISS: EDMS Development Future  IT/DB: Hardware + OS + Cluster + File Server + License Server + EDMS database and related application server + data safety  IT/PS: CADIM Client Support  EST/ISS: EDMS Development

After-C5: EDMS Service Migration October 4 th 2002 EDMS ID: M. Marinucci Lopez CERN-IT/DB 22 Conclusions  The new EDMS service will merge the existing central database cluster and the current EDMS cluster  More responsibility within IT/DB  Tentative production date is 1 st Q 2003
