  40. CHEPREO Tier3 Cluster Current Cluster configuration: • Gigabit Copper backbone with GE connectivity to AMPATH Network • OSG Computing Element • Approx. 23 computational cluster • Supports local user logins • Serves as the CE’s gatekeeper • Plus all other cluster services • This year added a “Storage Element” • This year added a very modest fileserver (lack of equipment funds) • Cobbled together from existing equipment, spare and new parts • 1.5 TB of disk added as a Network Attached NFS server • Upgraded OSG middleware stack

  41. Tier 3 Data Center: Current Usage • Usage Statistics (condor) • Since Nov. 2006 a total of ~30K hours used • Usage by a few of the supported VOs • Minor usage by CMS! • CMS can’t currently make much use of opportunistic grid resources • Requires several, heavy services, PhEDeX, SRM/dCache… • Very few non-Tier2 sites are actually used by CMS • Other HEP VOs just don’t know about FIU-PG…

  42. Projections & Recommendations • Projected Bandwidth Usage • Projected Tier-3 Growth Plan • Challenges with international bandwidth management

  43. Bandwidth Utilization Projections • RedCLARA projection due to direct peering w/ US R&E Networks over AtlanticWave • Distrib. Tier-2 projection due to further testing & preparations for LHC experiments • Astronomy projection due to images from Dark Energy camera

  44. International Network Support Recommendation • Continue CHEPREO funding support in Y5 to sustain 2.5Gbps link capacity MIA-SP • Essential to support research and production traffic flows between the U.S. and Latin America • Additional $426,000 over PEP CI funding • WHREN-LILA assumes this cost in FY08 & FY09 • Continue CI (Networking) personnel support at FIU & Caltech

  45. Tier 3 Projected Growth Plan for FY07(Y5 of CHEPREO) • Replace aging hardware • Xeon class server are now over 3 years old • Almost everything is already out of warranty • Replace 1.5 TB fileserver with modern hardware with more disk, more RAM and more CPU • Modest investment would yield 10X the storage • With modern storage server can consider deployment of a real grid enabled Storage Element • Add an interactive analysis server • Cost: Approximately $70,000

  50. FDT Test Results (2) 11/14-11/15 • Stable disk-to-disk flows Tampa-Caltech: Stepping up to 10-to-10 and 8-to-8 1U Server-pairs 9 + 7 = 16 Gbps; then Solid overnight • Cisco 6509E Counters: • 16 Gbps disk traffic and 13+ Gbps FLR memory traffic • Maxing out the 20 Gbps Etherchannel (802.3ad) between our two Cisco switches ?
