1. OpenLab Enterasys Meeting
January 23th 2003

2. 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

4. 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)

6. 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”
