High Energy Physics Division Computer LAN
About 200 hosts Most of them are 10Mbit/sec Central part of LAN consists of
100Mbit/sec segments (Full Duplex)– Based on 3Com Switches 3300
LAN is distributed over 5 buildings – Effective distance is about 800 m
Fiber Optic Cable is used in between buildings

What is an inspiration?
Last year (1999) that book became famous.
Immediately after a range of proposals were submitted to various agencies and funds.
Main idea is to create World Wide Computing Infrastructure.

Problems
Security – against attacks from Internet and Intranet;– against unplanned data losses;
To keep up to date the software base on whole cluster.
To save network bandwidth by keeping locally the special cache for experimental data.
Appropriate Batch System.

Possible Plan for Small Physics Laboratory
To install the hardware: (3-5) PCs (about 0.8-1.3 GHz, 0.5GB of main memory, DLT stacker on the base DLT-8000, Switch with 1 Gbit uplink, etc., etc.).
To install the software: Linux, CERNlib, Objectivity/DB, GLOBUS, etc., etc.
To prepare and test logical connectivity to CERN and to Regional Computing Facility for LHC.

Conclusion
Relatively new situation for many small and midrange laboratories (like PNPI):– Main direction in HEP computing at PNPI is
to create good front-end for High Performance Computing Facilities plus MSS outside Institute.
– We have to collect all the available financial, technical, administrative resources and plan to work in close collaboration.
