goals and objectives
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

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.

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

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.

plans and concerns
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
