D0 Operating Costs from CD

Stephen Wolbers

D0 Finance Board

November 18, 2002


Methodology
Methodology

  • Identify costs which are associated with D0 computing and are associated with operating the experiment:

    • Tapes in the STK and ADIC robots

    • Maintenance for hardware and software

    • People (mainly computer professionals) required to keep D0 computing operating


People
People

  • An MOU was developed in early 2001 to identify effort required to operate D0 computing:

    • Approximately 33 FTE were identified in a long list of categories.

    • This was used as a starting point to identify candidate FTE for operations.

  • The MOU will be updated over the next few months.


Categories of people
Categories of People

  • People are put into one of 5 categories (Matthias Kasemann list)

    • 1) - is this person working on the Core-CD-Responsibilities?

    • 2) - support of scientific user community

    • 3) - not[1,2,4,5] and would this person be necessary if CDF/D0 would stop operating?

    • 4) - this person works on PPD-Core_responsibility

    • 5) - hard to find the category for


People fte for operations
People (FTE) for operations

  • Category 3 of the previous slide:

    • Network (Computer Professional)

    • Hardware (Technician)

    • Code Management Support

    • Central Mass Storage

    • Software Products Support

    • Linux Desktop Support

    • Software Support


Costing the components
Costing the Components

  • Tapes – Use the purchase price

  • Maintenance:

    • Large hardware systems (SGI, SUN, STK, ADIC) – use the exact costs

    • ORACLE, CISCO – use lab wide cost divided by 3 (assuming CDF, D0 and rest of the lab are approximately equal users)

  • People:

    • Computer Professionals – use midpoint of CP6

    • Technicians – use midpoint of Technical Specialist

  • FY02: As spent, FY03: Estimated


Maintenance
Maintenance

  • Hardware

    • d0mino $345K (SGI central analysis)

    • ADIC robot $58K (ADIC robot + tapedrives)

    • STK robot $55K (STK robot + tapedrives)

    • d02ka $32K (SGI NFS server)

    • d0bbin $9K (SGI for farms)

    • d0ora1 $9K (SUN database production server)

    • d0ora3 $6K (SUN development database srvr)

    • TOTAL $514K

  • ORACLE/CISCO

    • Oracle $37K (1/3 of lab total assigned to D0)

    • Cisco $56K (1/3 of lab total assigned to D0)
