14. KOLKATA Tier-2@Alice Grid NEW Storage Via EOS  Started long back, but due to Space and Speed problem could not configure properly.  Tried different Linux versions, Planned to deploy on CC7 such that not have to upgrade in near future.  For CC7 deploy script have to be properly checked.  Finally decided to configure on SLC 6 only.

17. KOLKATA Tier-2@Alice Grid Planning and Roadmap  Last year did the Market Survey and discussed with Latchezar for the best configuration for the ALICE compute nodes:- – 2 * 12 core Intel Xeon Processors – Total 128GB of RAM ~ 5 GB/core or 2.5GB per Hyperthreaded Core – One 800 GB SSD – For better management and space requirement planed to have each server within 0.7 U – Total 48 Servers ~ 24 * 48 = 1152 Cores or 48*48 = 2304 logical Cores – Will be > 25K HEP Spec2006. – To avoid any SPF (Single Point of Failure) so decided to have N+N power supply and N+N Cooling Fans.

18. KOLKATA Tier-2@Alice Grid Planning and Roadmap Cont..  For the same procurement started last year.  Received 3 offers from HP, DELL and Fujitsu.  Unfortunately no one qualified for the N+N FAN Redundancy for the Dense or Blade server architecture.  Re-tendered the indent with modified specifications (removed N+N FAN Redundancy).  Added ~100TB storage via EOS under Kolkata SE.  Will start procurement for more storage approx 6*100TB servers. And will configure via EOS RAIN-6.  10 RDHx type racks allotted in the New Computer Hall for all the new infrastructure.
