Global Lambda for Particle Physics Analysis: SLAC setup
For the Bandwidth Challenge we plan to have the following
The 10GE NICs will be loaned from Chelsio and
We will have two 10Gbits/s links to SLAC from Sunnyvale from the
waves to get to Seattle.
The overall set of SC2005 links is shown
- Sunnyvale setup:
- Two Sun v20z's (these will be 1.8GHz Opterons loaned from BaBar) at
Sunnyvale (SNV) connected to 10Gbits/s. Setup.
Routing from SLAC.
- Ten BaBar loaned Sun v20z's with dual 1.8GHz Opteron cpus, 2GB main
at SLAC with 10GE Chelsio TOE Network Interface Cards.
- Four Sun v40z's with dual 2.6GHz Opterons with 10GE Neterion NICS,
acting as file servers
to a Sun 3510 fibre channel attached 1TB twelve disk tray.
- SC2005/Seattle in the SLAC/FNAL booth (number 302, see
- Ten Sun v20z's with dual 2.6GHz Opterons at
with 10GE NICs in the PCI-X 133MHz slot.
- Twenty * 2Gbits/s StorCloud direct Fibre Channel (FC) connections (i.e. 40Gbits/s)
with a storage capacity of 40TBytes. We will use QLogic loaned 6768 dual 2Gbits/s
channel Host Bus Adapters (HBAs) placed in the PCI-X 66MHz bus of each v20z.
- One Sun v40z acting as a file server to a 1TB disk tray with a 10GE interface.
- Six RAID disk servers with 1GE interfaces from Boston Computers.
- Two dual core Opteron systems with RAID disk from Boston Computers.
The UK (= UKLight+ESLEA+Manchester+UCL+ULCC) link is 8 * 1GE links between
disk servers in UK and on the floor. These would be PCs from Boston Ltd.
The circuits are level2 all the way out of UK systems and into Starlight
where they are presented as 1 GE. Within their first deadline we asked NLR
for onward 10GE link to the floor and after some exchanges we expect to
hear details in Aug. We think we would need a VLAN in the force10 switch in
Starlight to do this. The idea was to use level2 end to end, the floor end
being on the FERMI/SLAC stand.
The London - Starlight UKLight link will also support HPC and E-VLBI, so the
BWC would go down to 6 GBit, however yesterday Eric-Jan Bos of NIKHEF
suggested we could use 2 Gbit via Amsterdam as we did last year - so lets
work with 8 Gbit for now.
The bandwidth challenge racks at the SLAC booth are Sun StorEdge racks.
Each rack has two NEMA l6-30P plugs. Each plug feeds 9 110V outlets.
See the rack specifications manual for more
details on the racks, and
the layout of the two SLAC racks
for where things are planned to be located and power requirements. Also see
the spreadsheet for power details, and the
Power Management file for how to access the
remote power management.
The screw spacing for the rails is shown in the

horizontal mounts are shown
