Goals and Objectives l Flexibility on the Desktop (Low cost Seats) Access to networked services (X, http, IMAP) n Access to PC Applications n Reduce management overheads n Reduce costs n l Servers provide Compute power Central Servers for UNIX, VMS, Mail & Web n Compatibility with CERN / DESY / Fermilab n Provide Code development environments n 2 -3 April 2001 HEPSYSMAN 2001 2

Status l l l 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: 622 Mbs (limited by Firewall to 100 Mbs ) Campus backbone: Gigabit Ethernet Department Connected: 100 Mbs Internal Physics : 10 /100 Mbs 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. 2 -3 April 2001 HEPSYSMAN 2001 4

Status 2 l l l Additional CPU is provided by a Digital Alpha 500 au. New CPU provided by Linux. Just ordered a dual 800 MHz 2 GB 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 2 TB 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 ISDN 6 Tandberg. MS Netmeeting used frequently to DESY 2 -3 April 2001 HEPSYSMAN 2001 8

Plans and Concerns l l l 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 NT 4 provides all desktop functionality we need. Will look at Windows 2000 but no rush (at least for the desktop) cost of software licensing MAN POWER 2 -3 April 2001 HEPSYSMAN 2001 10
