5. w We want to provide a mixture of
a Tier 2 integrated in the AliEn Grid
a Tier 3 including a PROOF farm
integrated in the standard GSI batch farm (GSI, FAIR)
We want to be able to readjust the relative size of the different parts on request.
What we need to decide today? w
Can we decide today?
Do we need additional
information? How much time do we have?
Shall we go for local disks or not?
Do we want to split the money?
Is there synergy with FAIR? Should we buy s.th. useful for FAIR now and hope to get s.th. back later?...
