1. 1 SLAC Site Report By Les Cottrell for UltraLight meeting, Caltech October 2005

2. 2 SLAC Evolving Increasingly multi-program: –Increasing focus on photon sources SPEAR3, Linear Coherent Light Source (LCLS) and Ultra Fast Science Center –Increased funding from BES LINAC increasingly funded by BES (all in 2009) –HEP roughly stable, BaBar stops taking data 2008 Proposal for tier 2 W. Coast ATLAS/LHC site –Accelerator design –Astronomy: NASA (GLAST) and Large Synoptic Survey Telescope (LSST)) –Joint (Stanford / DoE / NSF) funded projects KIPAC, UltraFast center, Guest House

3. 3 Requires New business practices –More project oriented since multiple projects so need more accountability –No longer dominated by HEP Harder to “hide” projects like UltraLight/PingER with no sources of funding for operations. SLAC/IEPM part of BNL Terapaths project –Recently hired post-doc Yee-Ting Li to work on this

4. 4 Site Connectivity Connected to ESnet Bay Area MAN –ESnet (production) + SDN both 10Gbits/s –4Gbits/s disk to disk SLAC/NERSC for BAMAn Christening Have equipment to connect up production LAN at 10Gbps to ESnet, awaiting power installations For SC2005 built a ten node xrootD cluster of v20z dual Opterons with Chelsio and Neterion NICs, plus four v20z file servers and disk trays Attached to ESnet for SC2005 via temporary Cisco 6509

5. 5 UL Testbed 10Gbits/s Sunnyvale space loaned from CENIC, SLAC paid for power $1K/month, stopped being invoiced July ’05 –Status of permanent residency unresolved Cisco 6509 from UltraLight proposal Two Sun v20z dual 1.8GHz Opterons loaned from SLAC –10GE Neterion NICs, purchased by SLAC –Remote management Purchased/installed terminal server to provide console access Purchased/installed remote power management Will get file server from Caltech? Connect hosts to Cisco 6509, to 10Gbps UltraLight Tie in/interconnects between ESnet, USN & UL unclear –USN has 2 circuits to UL router –ESnet (SDN) has circuit to USN –ESnet BAMAN has connectivity to SLAC Main costs to SLAC are people costs for which there is no directed funding to support

6. 6 Sunnyvale set up V20z dual 1.8GHz opterons Linux 2.6.9, Neterion 10GE NICs NO uldemo account allowed.5.3.6 A3 A4 A5 A6 A2.8.7.4 Power Console 10Gbits/s UltraLight (192.84.86.x) CENIC http://137.164.37.3http://137.164.37.3 power management UltraLight 10Mbps management(137.164.37.x).114.115 Terminal Server Hub Compute servers Not installed.2 6509 snv2 snv1 Te2/2 Te2/4 Te1/2 USN ESnet BAMAN Te2/1 Te11/3
