Tier2 Facilities

Tasks and Deliverables

1. Obtain current inventory of deployed project and leveraged Tier2 facilities
   • Spec Int/TB for Funded, Dedicated, Leveraged (ATLAS usable)
   • Due 5/31
2. Deployment plans/profiles of new cluster facilities at each Tier2
   • Spec Int/TB plans
   • Timeline (RFP, Procurement, Infrastructure, Deployment)
   • Due 6/30 I

1. Fabric management systems: recommendations for standardization, or not; Rocks commonanilties?
   • No, Use most expedient process.

1. Tier2 data services: deployment and operations
   1. Document model, configuration, operational guide
   2. ATLAS distributed databases See next section
   3. DDM servers Expect Tier 1 to take this over

Site architecture and configuration

Treat funded tier 2 facility as black box.
Define minimum interfaces not exhaustive:

• Number / Type of gatekeepers
• Number / Type of SE's
• Dedicated machine(s) for Conditions/Cal DB
• Dedicated OSG ITB node
• Tier 2 interactive nodes?

Monitoring and Accounting - what are precise monitoring requirements: * which site-level systems are monitored, * reporting to which top-level servers. - accounting for RAC purposes - accounting for LCG purposes - accounting for OSG purposes

- service alerts and monitors * What services should generate alerts * Additional Monitoring for diagnosis

Policy publication and implementation - GUMS configurations - Not only the queues, priorities, and quotas, but also Tier2 usage by general ATLAS users (analysis, production, interactive) - local scheduler configurations (PBS and Condor) - publication of US ATLAS and site-level policies. - policy change control

OSG integration - running OSG services on Tier2 resources - integration / validation of ATLAS on OSG - supporting other VOs on usatlas resources - interfacing to OSG operations, security, etc

Milestones

Define major milestones here, eg:

• Delivery of phase 1 cluster at MWT2
• Phase 1 SWT2 cluster operational

where "Phase 1" is something to name a Specint+TB capacity.

Schedule

Tier 2 external Interface document * Flesh out requirements at Wed. meetings * Have first draft available in 1 month * Have full definition available in 3 months

NET2

SWT2

MWT2

• Vendor selection for Phase 1 procurement
• Delivery of Phase 1 equipment to IU and UC
• Phase 1 Tier2 operational
