1. April 2001HEPix/HEPNT1 RAL Site Report John Gordon CLRC, UK

2. April 2001HEPix/HEPNT2 Summary Old New Grid

3. April 2001HEPix/HEPNT3 Old HP farm closed down –to most users October 2000 –To all February 2001 NT Farm –LHCb production finished end of Feb 2001 –Most machines moved to Linux then (10x450MHz duals) –Core Farm remains so could be brought back into use

4. April 2001HEPix/HEPNT4 Security Site Policy Firewall Only specified ports allowed in to certain machines No incoming access to the rest –has reduced scanning Auditing critical services

5. April 2001HEPix/HEPNT5 New BaBar CDF Linux Data Storage

6. April 2001HEPix/HEPNT6 BaBar 4 Sun 420R = 16 cpus Accessing existing 6TB disk served by E4500

7. April 2001HEPix/HEPNT7

8. April 2001HEPix/HEPNT8 CDF Funded by JIF (government programme) Still out to tender Large disk and SMP server(s) –at RAL + 4 UK universities –5TB plus 2x8-way servers 16 node farm at RAL Use of Datastore (10-20TB) Similar to original BaBar bid

9. April 2001HEPix/HEPNT9 Linux Farm Was 120 cpus 40x450Mhz + 80x600MHz Added 20x450 from NT Farm in March Added 48x1GHz duals in APril 236 cpus >100GFLOPS peak 1GHz cpus show wide variation in benchmarks

15. April 2001HEPix/HEPNT15

16. April 2001HEPix/HEPNT16 Network RAL now connected to ThamesValleyNet MAN @ 622Mbit –connected last week –Oxford, RAL, Reading –hence SuperJanet4 2.5Gbit UK national backbone RAL site backbone –a number of Nortel Gigabit switches –replacing FDDI (still in parallel)

17. April 2001HEPix/HEPNT17 Network HEP services network –2 Extreme Networks Summit 7i copper Gigabit switches –testing Intel EEpro1000 copper NIC - looks good Experimenting with wireless ethernet –outside firewall, PPTP to come inside

18. April 2001HEPix/HEPNT18 Grid Testbed 15 dual 1GHz planned 10-15 borrowed from Linux Farm for now 2x1.4TB IDE disk servers Gigabit switch Globus 1.1.3 and PBS –unless WP6 decides otherwise.

19. April 2001HEPix/HEPNT19 GASS and Datastore Datastore User globus-rcp globus-url-copy Gass server gsiwuftpd gsiftp/http vtp

20. April 2001HEPix/HEPNT20 Grid Access to Datastore We have implemented a Globus GASS server which will serve data from Datastore over Grid using GSI and globus i/o tools –globus-rcp, globus-url-copy, Globus i/o library Plan to implement GridFTP server in same way
