  1. Oxford Particle Physics Site Report Pete Gronbech Systems Manager Hepix 1999

  2. Server based computing • Low Cost Seats • Central Unix Server • Central VMS Server • Central Mail Server • Central Web Server Hepix 1999

  3. Goals and Objectives • Flexibility on the Desktop • Access to networked services (X, http, IMAP) • Access to PC Applications • Reduce management overheads • Reduce costs • Servers provide Compute power • Compatibility with CERN / DESY • Provide Code development environments Hepix 1999

  4. The Server / Desktop Divide Servers General Purpose Unix Server VMS Server Mail Server Web Server NTServer Unix Workstation NT PC NTPC NT PC NT PC Desktops Hepix 1999

  5. Goals and Objectives 2 • Aim to standardise and centralise as much of the IT infrastructure as provides real benefit across whole department. • Aim to provide HEP specific computing on top of basic infrastructure - basically compute servers • Desktop Strategy - Windows NT Workstation (80 particle physics 200 across physics) MS Office, eXceed, Web browsers, Mail clients etc. Systems generated by cloning (with GHOST) and used by wide range of users • Server Strategy - HEP Computation - Heavy use of remote compute farms, local compute server (Digital UNIX 3 CPU server) for interactive work especially code development. Recently Linux for CDF group Hepix 1999

  6. Linux Treat Linux as just another Unix and hence a server OS to be managed centrally. Wish to avoid badly managed desktop PC’s running Linux. Servers RAL Linux Farm Porting Machine CDF Linux (Dual 400MHz PII) Unix Workstation NT PC NTPC NT PC NT PC Desktops Hepix 1999

  7. Goals and Objectives 3 • Server Strategy - IT in general - NT server (6) for desktop file/print, Exchange 5.5 for email, IIS 4 for web serving, Ntrigue for network access to PC applications. Just installed MS Terminal Server to give NT 4 remote access to replace Ntrigue. • VMS - DAQ systems still important but general purpose service is running down (mail, word processing etc going to NT) • Data Acquisition - LABview on NT for most laboratory DAQ and control (used by wide range of research groups) • Videoconferencing - PC based Intel plus access to ISDN6 Tandberg. MS Netmeeting used frequently to DESY Hepix 1999

  8. 100Mb/s Hepix 1999

  9. Performance Hepix 1999

  10. Standard NT PC Clone circa 1995 • Pentium 100MHz • 1GB Hard Disk • 16MB Memory • Quad Speed CD Rom • Sound Capability • Diamond Stealth 64 DRAM • 17” iiyama Colour Monitor • 10Mb/s Network Card Hardware Custom Built to our spec for about £1.6K inc. VAT and Software Licenses Hepix 1999

  11. Standard NT PC Clone circa 1999 • Pentium II 350MHz • 8GB Hard Disk • 128MB Memory • 32 Speed CD Rom • Sound Capability • AGP Rage Pro Graphics • 17” iiyama Colour Monitor • 100Mb/s Network Card Hardware Custom Built to our spec for about £1.2K inc. VAT and Software Licenses Hepix 1999

  12. Network Access The Internet Use telnet or ssh to access al1.physics.ox.ac.uk from outside the pnp subnet al1 r series commands restricted to within pnp subnet. No telnet, ssh, or ftp access from outside subnet. pnp subnet 163.1.243.x 163.1.244.x al? al? al? al? al? al? Hepix 1999

  13. Hepix 1999

  14. Plans and Concerns • Look to replace local compute server in 1999 (Alpha?) • NT4 provides all desktop functionality we need. Will look at NT5 /NT2000 but no rush. • choice of OS/platforms for computation. (if Linux which version?) • cost of software licensing Hepix 1999

  15. Conclusions • Unix servers dictated by experimental collaborations • Standardised NT PC Clone • Less variables - Simpler to manage • Commodity Hardware and Software • More cost effective • Minimise the systems management Hepix 1999
