Hello all, Tim and I put together a basic roadmap for DM subsystem and LSST system integration and test activities (posted as Document-1995). This roadmap is being worked into the overall DM roadmap and estimates. Please use this as a guideline for when we need to acquire infrastructure, i.e. ensure that we plan to acquire the infrastructure in time to do burn-in/checkout and configuration before needing it for test and integration.
Based on this roadmap, in answer to Ray's question at the TechAssessWG yesterday, I believe we can acquire the archive services computing/storage at the archive center at the start of 2011. The base facility infrastructure will be acquired sooner (in 2010 and early 2011) and configured first at the archive center and then moved to the base facility when the physical plant is ready for it. At that time we will "backfill" the base "clone" that will live at the archive center. Note that we will not deploy the Data Access Center until Commissioning, which is currently an Operations Phase activity. However, we will carry the cost of the first year of Data Access Center infrastructure under the Construction Proposal for now, until we find out if the NSF will require us to budget for it in the MREFC proposal. Also, please note that we have estimated a development system for software development under the Auxilliary and Support WBS. This will be acquired early in Construction. At next week's telecon, we will discuss the ramp up of the archive services computing/storage for re-processing/data access. We want to apply a just in time acquisition strategy to take advantage of favorable cost trends over time.
