OpenLab Enterasys Meeting January 23th 2003

Goals for Openlab Networking Understand, Implement and Manage a large, high bandwidth infrastructure Promote the use of 10 Gigabit Ethernet as a switch interconnect and a host attachment Demonstrate that Ethernet Technology is well suited for LHC data acquisition and offline processing .. And demonstrate that Enterasys can do the job better than others Openlab Enterasys 23-january-2003

Status end 2002 Problems with the 10 Gbps interfaces in the ER16 Very reduced setup to isolate the problem Took some time to diagnose and fix 10 Gbps cards are not back to CERN yet E1 OAS not fully tested yet Therefore, the proposed setup has not been installed New request for more connections (HP) 32 nodes with 1 and 10 Gbps NICs announced New request for higher speed data challenges 1 GigaByte/s thru the complete chain (from CPU to tapes, via disks) Openlab Enterasys 23-january-2003

Proposed extension 1Q2003 32 32 node Itanium cluster Disk Servers 1-12 13-24 25-36 37-48 1-12 13-24 25-36 4 4 4 2 2 2 E1 OAS E1 OAS 2 32 2 E1 OAS E1 OAS 4 4 4 4 1-96 FastEthernet 49- 60 61-72 73-84 85-96 Gig copper 32 node Itanium cluster 200+ node Pentium cluster Gig fiber 10 Gig Openlab Enterasys 23-january-2003

What next for 2003? Proposals Improve/adapt the current setup to accommodate higher data challenge speeds Work toward a solution for connecting more HPs at 10Gbps Interconnect this heterogeneous cluster with WAN equipment to validate the “gridification” Openlab Enterasys 23-january-2003
