Future Resources • New Mo. U’s show lack of Storage space at Birmingham, and Jet, with a problem at Bristol in 2014 • Shortage of CPU at Birmingham by 2014. • This all assumes current levels of resources at sites. Old storage and CPU will come out of warrantee and be retired so new purchases need to maintain enough resource to cover the Mo. U commitments South. Grid January 2012 8

DRI Grants • An unexpected bonus was the Digital Research Infrastructure Proposal. Work started in late October, and by the end of the year we had submitted grant requests for a total of £ 3 m. 10

Procurement deadlines etc • Both the Grid. PP 4 h/w grant and the DRI money must be spent before the end of this Financial Year ie 31 st March 2012. • Orders had better be made now or very soon. • Invoices should be paid before 31 st March 2012 South. Grid January 2012 11

Sussex • Suspended or Candidate sites • • Later this week, sites in suspended or Candidate state for longer than 6 months will be closed - COD has collected a list of exceptions from NGIs. This does not affect any Grid. PP site, except maybe Sussex. I note that as per https: //ggus. eu/ws/ticket_info. php? ticket=78177, Sussex is set as 'Uncertified', (my memory says it used to be 'Candidate', although I can't recall what the difference between the two is right now). • Plans to grid enable…. South. Grid January 2012 12

SL 4 EOL • SL 4 support finished yesterday – What servers are still out there • LCG-CE • DPM • ? ? South. Grid January 2012 14

Conclusions • • • South. Grid sites utilisation level except maybe RALPP? JET will be setup for ATLAS production new h/w will help. RALPPD still our lead site. Sussex, Warwick and Swansea had DRI money, what will this lead to? Main goal at the moment is to spend the two grants asap. South. Grid January 2012 15
