Platforms Windows XP replacing NT 4 and 2 k on desktops & machine controls Platforms Windows XP replacing NT 4 and 2 k on desktops & machine controls new server installations are Windows 2003 Server Solaris/SPARC: 2. 6 - 9 (mainstream: 8) last Solaris/x 86 to go this year Linux/x 86 DL 5 (Su. SE 8. 2) replacing DL 4 (Su. SE 7. 2) to come: Linux/amd 64 HP-UX, IRIX: gone or scheduled to go; AIX: few servers w/o central support: debian/x 86, Red. Hat 7, some OS X. . .

Windows new domain win. desy. de in production since January XP, 2003 migration from Windows new domain win. desy. de in production since January XP, 2003 migration from old domain in progress more than 1000 accounts and 500 PCs exist in new domain several smaller groups already migrated completely largest group of Windows users (Hasylab) started in April Samba Server migrated to 3. 02 other groups begin with smaller work groups or projects Samba 3. 02 print server is a domain member

Linux DL 5 (Su. SE 8. 2) rollout in progress (25% done) support for Linux DL 5 (Su. SE 8. 2) rollout in progress (25% done) support for base distribution ends April 2004 9. 0 patches will help for another 6 months successor - better: continuation - needed early next year DL 5 is most likely the last DESY Linux based on Su. SE if a common HEP distribution with long lifetime is available and affordable, that's what we'll use started looking at Scientific Linux thanks to Fermilab for providing this! current version seems very compatible with DL 5 (for users) purchase of licenses is an option - if price/value ratio ok

Linux/amd 64 aka ia 32 e aka x 86_x 64 first test system is Linux/amd 64 aka ia 32 e aka x 86_x 64 first test system is a success IBM e. Server 325, 2 x Opteron 246 (2. 0 GHz), 4 GB RAM Su. SE 9. 0 Professional/amd 64 performs superior to fastest Xeon Systems (3. 2 GHz) except FP ROOT applications especially fast, benefit from 64 bit mode deployment of a small number of production systems soon seamless integration is relatively easy concern: cernlib dependency locks users into 32 bit past

GRID participation in D-GRID and EGEE DESY Grid Testbed 2 in operation, see http: GRID participation in D-GRID and EGEE DESY Grid Testbed 2 in operation, see http: //grid. desy. de complete LCG 2 site, including RB and BDII

Grid Testbed 2 operated in Hamburg on Red Hat 7. 3. 3 systems includes Grid Testbed 2 operated in Hamburg on Red Hat 7. 3. 3 systems includes nodes in Zeuthen, running on DL 5 running: WN, CE, UI; in preparation: SE, RB data management service includes SRM and Grid. FTP SE with d. Cache backend developed & being tested resources are included in LCG 2 head site at CERN D-GRID partners are using DESY's Resource. Broker DESY is Tier 0 and Tier 1 center for HERA VOs exist for the active HERA experiments, linear collider activities, international lattice data grid

Security rules for individually maintained systems are in effect now regular scans from outside Security rules for individually maintained systems are in effect now regular scans from outside our firewall of all hosts with any port open through firewall for open ports and known vulnerabilities by commercial service provider access to mail servers now by imaps only got rid of clear text protocols pop and imap automated deployment of patches linux, old NT domain (netinstall), new XP domain (SUS) policies still evolving

Security continued due to recent sasser threat, manually checked ALL notebooks brought on site Security continued due to recent sasser threat, manually checked ALL notebooks brought on site for two days only a few systems got infected increased update frequency for virus signatures update server: hourly, client: every three hours a few users were tricked into installing Bagle. J lesson: treat encrypted attachments like executables, and quarantine them firewall now inhibits outgoing SMTP, except for approved mail servers imagine all sites and providers did that

Mail & Groupware MS Exchange 2003 only candidate for a DESY-wide central service planning Mail & Groupware MS Exchange 2003 only candidate for a DESY-wide central service planning integration into new windows domain may also become the solution for Linux/Unix users evaluating Exchange Connector for Ximian Evolution but has many requirements library versions not available from distributions (incl. SL 3) deployable without red carpet ? no successful test installation yet consolidation of mailing list administration will move from PMDF to Sympa, for whole lab

Web Office support for any DESY group providing web content centrally supported servers setup Web Office support for any DESY group providing web content centrally supported servers setup with load balancing & failover full access to backend services like oracle Zope application server ZMS content management system instantiation of new virtual sites within minutes including structure and design

Disk Storage HP MSA 1000 systems installed in Hamburg & Zeuthen used for Windows Disk Storage HP MSA 1000 systems installed in Hamburg & Zeuthen used for Windows home directories experience is good, system is easy to handle performance problems for NT 4 Clients to W 2 K 3 server probably not the devices fault. . . Storage. Tek D 178 systems installed in Hamburg & Zeuthen not without flaws several downtimes (planned & unplanned) during past year FC, SAN & $$ no guarantee for availability

Disk Storage (medium grade) continuous demand for high volume affordable storage d. Cache read Disk Storage (medium grade) continuous demand for high volume affordable storage d. Cache read cache; MC/data accessible by NFS, AFS, CIFS no way to provide this but IDE-RAID past: 3 ware Escalade (still used in workgroup servers) now moving to SCSI/FC attached subsystems Infortrend IFT 6 xxx, more recently: Eon. Stor A 16 xx (SATA) better MTBF of disks (due to lower vibrations ? ) Eon. Stor teething problems (still frequent firmware upgrades necessary, controller chip data corruption issue in 2003) d. Cache still detects data corruption at 1 E-12 level first linux AFS fileservers with O(TB) partitions/volumes

Miscellaneous News batch: SGE(EE) test installation in Hamburg is up (production is LSF) has Miscellaneous News batch: SGE(EE) test installation in Hamburg is up (production is LSF) has been in production on common farm in Zeuthen for years now running with krb 5 integration (through arc. X) acron/arc successors from two student projects available k 5 cron (Hamburg) & arc. X (Zeuthen) - see talk by W. Friebel draft of common usage regulations well advanced planning an infiniband evaluation cluster for this year new 155 Mb/s connection Hamburg-Zeuthen with flat fee allows projects impossible before (alas, still no redundancy)
