  1. Oxford Particle Physics Site Report Pete Gronbech Systems Manager HEPSYSMAN 2001

  2. Goals and Objectives • Flexibility on the Desktop (Low cost Seats) • Access to networked services (X, http, IMAP) • Access to PC Applications • Reduce management overheads • Reduce costs • Servers provide Compute power • Central Servers for UNIX, VMS, Mail & Web • Compatibility with CERN / DESY / Fermilab • Provide Code development environments HEPSYSMAN 2001

  3. 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 HEPSYSMAN 2001

  4. Status • General Setup remains the same with NT PC’s on the Desktop and Various UNIX/VMS/NT servers in the Computer Room. • Super Janet 4 connection: 622Mbs (limited by Firewall to 100Mbs )Campus backbone: Gigabit EthernetDepartment Connected: 100Mbs Internal Physics : 10 /100Mbs switched • Server Strategy - Heavy use of remote compute farms, Local CPU will be provided by Intel Linux systems. Digital Unix systems and legacy VMS systems. HEPSYSMAN 2001

  5. Network Access Super Janet 4 Just upgraded to 622Mb/s; OUCS firewall to be upgraded to 1Gbps speed shortly Physics Backbone Switch 100Mb/s Physics Firewall OUCS Firewall 100Mb/s 100Mb/s Backbone Edge Router 1Gb/s 100Mb/s Campus Backbone Router 100Mb/s 1Gb/s depts Backbone Edge Router depts 100Mb/s depts 100Mb/s depts HEPSYSMAN 2001

  6. al1 Digital 2100 Server 3 CPU’s 512MB RAM 216GB Disks HEPSYSMAN 2001

  7. al17 - A Digital Personal Workstation 500au 9 * 50GB disks in the Datasilo HEPSYSMAN 2001

  8. Status 2 • Additional CPU is provided by a Digital Alpha 500au. New CPU provided by Linux. Just ordered a dual 800MHz 2GB RAM system for SNO analysis. • Oxford is the ‘Lead site’ for successful CDF_JIF bid, multi-cpu server plus 1 TB store in each CDF institute. Plus larger 2TB store at RAL and even larger at Fermilab. • Server Strategy - IT in general - NT server (6) for desktop file/print, Exchange 5.5 for email, IIS 4 for web serving, MS Terminal Server to give NT 4 remote access. • 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 HEPSYSMAN 2001

  9. Linux pplx1 Fermi 6.1.1 pplx2 RH6.1 ppnt109 RH6.1 pplx3 RH6.1 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 GENERAL RAL Linux Farm Porting Machine MINOS Linux/NT DAQ SNO Linux CPU Server CDF Linux (Dual 400MHz PII) Unix Workstation NT PC NTPC NT PC NT PC Desktops HEPSYSMAN 2001

  10. Plans and Concerns • Look to replace local compute server with RAID Disk Server and Linux CPU servers. Disk server could be Intel based running NT or Linux but if performance is not sufficient a proprietary solution may be used. • Experience gained with CDF distributed data store will help plan LHC requirements. • Choice of OS/platforms for computation. Clear that this will be Red Hat Linux • NT4 provides all desktop functionality we need. Will look at Windows2000 but no rush (at least for the desktop) • cost of software licensing • MAN POWER HEPSYSMAN 2001
