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

  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

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

  7. Fast Ethernet Gigabit Ethernet SCSI2 FWD Fibre Channel Data Path to the SILO from HallB SCSI-2 FWD SUN E4000 Cisco Cat 5500 Cisco Cat 5500 Gigabit Ethernet 4 Fast Ethernet Redwood tape drives 2,5,6 1 3 SUN E3000 Fibre Channel Fibre Channel 4X30GB 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 1 CLAS DAQ

  8. 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

  9. 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

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

  11. 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

  12. 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
