3. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Central Cluster Moved to Tru64/TruCluster v5 –3 nodes interconnected by Memory Channel Improved file server performances –Cluster File System : no NFS inside the cluster Failover and Load balancing –Better transition time (<30s for filesystems) –Cluster aliases –Multi-instance applications

4. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Windows Infrastructure Still growing… Domain server migration to W2000 complete “Massive move” of desktop to W2000 –Done via SMS Use a combination of AD and SMS –SMS mainly for Virus signature update and SP –May be used to solve the “too stable” syndrome

5. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Linux (server) Red HAT 6.2 in production –plan to move to 7.x NFS client performances –Kernel 2.2.18 is a huge improvement AFS client released by openAfs –Testing kernel 2.4 AFS client working ? Kernel updates are time consuming –But needed for NFS reliability and performance

6. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Linux (desktop) Not supported except for laptops –NFS filesystems not exported vmware offers an attractive alternative easy(er) to manage (even for laptops) –Main OS : W2000 Managed by SMS/AD –Linux in VM One file to distribute

7. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Metaframe / Wincenter Remains a crucial service –Growing number of simultaneous users Starting a second machine –W2000 + Metaframe –Move from X11 on Metaframe to ICA clients on Unix –Will implement load balancing

8. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Distributed Computing Initiatives Involved in GRID testbed and XtremWeb –XtremWeb : Auger simulation –1 person to work on GRID application Jumped into 1U packaging –10 Dell 1550 (dual CPU 866 Mhz) –Cost penalty : 20% Same price as HP XM workstation

9. 26/4/2001 LAL Site Report - HEPix - LAL 2001 Future Directions Servers –Heterogeneous SAN –Backup robot upgrade : LTO ? Desktop –W2000 : Move to DFS –W2000 : Use PrintPackage from CERN –Linux support on the desktop ? Lack of manpower
