Last Updated 1.11.2007: Clarify site resource offers as real percentage of requirements and when normalised to 100% of ALICE requirements.

Updated 05.10.2007: Add new 2008 Tier-1 pledge percentages (normalised to 100%) and Full Scale Dress Rehearsal (FDR) plans for end 2007/early 2008.

Updated 25.06.2007: Split off 2006 plans into a separate linked page and remove LHC engineering run.

Updated 5.03.2007: add planning of full scale dress rehearsal of p-p running beginning in April 2007 and continuing throughout the year.

Updated 25.10.2006: continue the data export tests till end 2006 and add resource requirements for all of 2007.

Updated 18 August: continue the July 300 MB/s export tests until succesful.

Updated 4 August: correct T1 cpu resources required for the network/reconstruction stress test. In fact half the resources will come from T2 sites.

Updated 12 June: add scheduled dates of 24 July to 6 August for T0 to T1 data export tests.

Updated 2 June: add planned July Tier 0 to Tier 1 tests at an aggregate rate from CERN of 300 MB/sec.
