Verbesserung gegenüber heute: Primärstrahlintensität 100 – 1000 x

Sekundärstrahlintensitäten für radioaktive Kerne: bis 10 000x

Ionenenergie: 20 x

Neu: schnell gepulste supraleitende

Magnete

„gekühlte“ Antiprotonenstrahlen bis 15 GeV

Speziell: intensive „gekühlte“ Strahlen radioaktiver ‚exotischer‘ Kerne

effizienter Parallelbetrieb für mehrerer Experimente

IT

• Linux (Debian) ~ 350– (SUSE) ~ few

• Windows ~ 800• AIX (reducing) ~ 10

– plus bio physics ~ 20• VMS ~ 15

– plus Accelerator controls (~30)

• Notebooks– Windows (XP)– Linux (SUSE)

• Mass storage (3 libraries, TSM, TSM-API access)– 2 SAN based (Storage Tek with LTO-2 tapes drives)

What is new

• Firewall (Cisco PIXS)• Linux MTA (2-3) (migrate from AIX)

– Spam filtering (tagging) (Spamassassin)– Virus checking (Sophos, ClamAV)– Problems: Siesta (~20 min)– enforce GSI e-mail naming convention

(H.Kreiser@gsi.de)

• DNS Service migration to Linux (from AIX)– connection timeouts on AIX

What is new

• new Fileservers with Serial ATA disc raids– 3 U boxes with up to 15 discs– Data– Scratch– Problems with old IDE disc raids

• new batchsystems (1 U boxes, Dual Xeon, 3.2 GHz)

• Windows migrate to XP, Server 2000/2003• phase out WinNT (this year)

Systems

What is new

• Debian 3.0 r2• non interactive daily security updates with

„out of the box“ debian tools• monitoring system (mon)

– processes

– disc status

– log host (syslog-ng)

– perhaps box status

• GRID, LCG -> need systems and support

What is to be done

• Migration of services from AIX to Linux– radius– listserv– NIS (sign on, LDAP based)– …..

• Groupware (mailserver) discussion– Microsoft Exchange 2003– OCS (Oracle collaboration suite)

• separate discussion forum (FUD forum, open source)• Discussion: new Batch queueing system

– LSF production (money)– SGE– OpenPBS

• if money is available– replace old batchfarm boxes– new and much more storage systems (user, data, scratch) SAN/FC ?– ~ 10 TByte is too small– good Linux desktop support -> manpower ??
