10:00 → 10:15 Resources (WLCG and D-CMS)

* DESY (ChW) - WLCG: CPU: 11.8 kHS06; Disk: 640 TB (will available by Jan 2010) - In total for CMS: ~1800 CPU slots (fairshare target), new CPU in 2nd half 2011, details depend on available money. ~200TB more storage additional space during first months of 2011. No clear plans beyond that. * RWTH (Th.K.) - WLCG: CPU: 6.6 HS06; Disk: 330 TB - in case the request for additional funding will be succesful we could provide for CMS (WLCG pledges plus DCMS resources together) ~3900 cores, 1.4 PB disk in spring 2011. If unsuccesful, then about 3000 cores, 0.9 TB. * KIT - WLCG (2010): CPU: 10,5 kHS06; Disk: 1,5 PB TB; Tape: 2,5 PB (CMS Tier-1) + 0,5 PB (local storage) - WLCG (2011): CPU: 15,0 kHS06; Disk: 2,0 PB TB; Tape: 5,2 PB (CMS Tier-1) + 0,5 PB (local storage) - NRG: CPU: 10,5 kHS06; Disk: 380 TB; Tape: 360 TB (CMS-Share is 30% of these resources) * NAF plans Now ~1500 CPU cores. First generation of CPUs to be replaced beginning of 2011, should increase CPU power but not the number of slots. Future of Lustre not yet clear.
