1 Jefferson Lab Site Report Sandy Philpott Thomas Jefferson National Accelerator Facility Newport News, Virginia USA Sandy.Philpott@jlab.org 757-269-7152 http://www.jlab.org/CC HEPiX - SLAC, 10/7/99

2 FS1,2,7 - NetApp /home,/apps, /group,/site FS3/4,5/6 - Symbios /work SUN E4000 OSM Symbios /stage CIFS (NetApp) NFS JLABN* NT Domain JLABA/H/S Central Computing IFARMA/H/L/S Interactive farm FARMA/L/S Batch farm - LSF Jefferson Lab Common User Environment (CUE) STK Redwoods Mass Storage DAQ Specialized Workgroup Clusters NFS Central Fileservers OS: A-AIX 4.1.5 H-HP-UX 10.20 L-Linux RH5.2 N-NT 4.0 S-Solaris 2.6 GP EP both Network: RAServer jput/jget DLT jukebox jexport

3 Systems Common User Environment –UNIX Solaris – 2.6; stable Linux – Intel, RH 5.2 (2.2 kernel); growing; farm and user desktop; limited desktop support HP-UX – 10.20; CAD, DB AIX – 4.1.5; support frozen (very few) –Windows NT 4.0 W9x support ends 6/30/00 –Macs support existing machines, not new purchases

4 Physics Computing RAID - Symbios –Additional 2.5 TB; total of 5 TB –Host (stage, cache; 1TB) and network (work; 4TB) attached Farming –25 additional Linux dual-processors; total of 75 –10 dual SUNs and IBMs still in for now –LSF licensing issue -> PBS? (talk later today) Mass Storage – STK, OSM –Write code to distribute OSM across servers? –Enstore? Others? –Silo 5 new 9840 drives installed; need local s/w modifications Upgraded to Powderhorn robotics

5 Physics Computing (cont) Silo is moving +1TB/day; ~700 mounts Currently 2700 SPECint95 Plan to double farm this year; +50 dual machines Interactive farm –2 SUN E450s –1 quad Linux – plan to expand Mprime for PC CPU/memory checks

7 Data Path from Halls A and C Cisco Cat 5500 Cisco Cat 5500 SUN E4000 SUN Ultra2300 SUN Ultra2300 4X18GB 324GB 270GB Redwood tape drives Gigabit Ethernet Fast Ethernet SCSI-2 FWD SCSI-2 UWD HallA DAQHallC DAQ 1 11 1 22 22 22 2 3 stage 1) Write raw data locally 2) Copy raw data to MSS stage disk 3) Copy staged raw data files to tape Fast Ethernet Gigabit Ethernet SCSI2 FWD SCSI2 UWD

8 Data Path to the SILO from HallB Cisco Cat 5500 Cisco Cat 5500 SUN E4000 SUN E3000 4X30GB Redwood tape drives Gigabit Ethernet Fast Ethernet SCSI-2 FWD CLAS DAQ Fibre Channel Fast Ethernet Gigabit Ethernet SCSI2 FWD Fibre Channel 1 13 4 1) Write raw data locally on the DAQ system 2) Unmount the full raw data disk from the DAQ system 3) Mount the full raw data disk on the MSS system 4) Copy raw data files to tape 5) Unmount the raw data disk on the MSS system 6) Mount the raw data disk on DAQ system 2,5,6

9 Network Backbone -> Gigabit –Foundry BigIron 4000 switching routers –Foundry FastIron II switches 70% of lab is on switched networks Gigabit being deployed between buildings as appropriate –Switches being deployed at the same time RIP -> OSPF in progress

11 High Performance Computing QCDSP – Lattice QCD for Theory group –1024 DSP’s (from FSU) –“Columbia Machine” 20 Alphas – Linux RH 5.2 –Collaboration with MIT, Wuppertal for LQCD Meta-facility –Parallel application development

12 Other Developments Recent purchases –Netscape Calendar –Microsoft SMS hardware/ and software inventory Remote control Software distribution –VMware NT running under Linux

13 Other Developments (cont) DMZ implementation (yesterday’s talk) Web services –From 1 central to 6 distributed servers –Linux/Apache standard configuration –Better flexibility for groups Host/System management project –DNS –System configurations –User management

14 Outstanding Issues Linux desktop access to home directories – Samba? LDAP - to solve –NIS Linux problem? –roaming profiles? –HEP directory NT/UNIX –UID/GID synchronization? –password integration? (Passync didn’t work out) –Account generation Future dual-protocol fileserver purchases? –Symbios? HP? SUN? DHCP
