Server based computing
Low Cost Seats Central Unix Server Central VMS Server Central Mail Server Central Web Server
14th April 1999 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

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

Machine
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.

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

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
