W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct BAHIA - interactive front-end Introduction of multi-processors: AIX > 6 * F40 HP-UX > 7 * HP9000/780/J282 Solaris 2.6 -> 3 * Ultra-4/E450 Linux (based on RedHat 5.2) -> 2 PentiumII450
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Merging of the 2 batch clusters Merge into one general cluster with 4 platforms (about 120 stations in total) New version of BQS: support of new platforms and new options New job submission options: IObound or CPUbound Present statistics: UI/month, ~75% cpu
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Networking - LAN Replacement of ATM by: Fast Ethernet (100 Mb full duplex) --> to interactive and batch services Giga Ethernet (1 Gb full duplex) --> to disk servers and Objectivity/DB server
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Networking - WAN Project “Renater 2” based on virtual networking (ATM) with guaranteed bandwidth. See the presentation of this project by Chafia Tifra.

8 Disk space Need to make the disk storage independent of the operating system. New disk server based on VSS (Versatile Storage System) from IBM with 1 TB and 2 F50 processors, mainly for xtage and Objectivity (test).
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Support for BaBar Objectivity/DB server (v.5.1 on Solaris 2.6) with 1 TB HPSS with interface to Objectivity database for BaBar ams --> oofs --> ooss --> HPSS 6 Redwood drives for HPSS HPSS server on AIX 4.3
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Local software developments UserSupport : see the presentation by Jean- René Rouet Management and tracking of the “help desk” problems Based on WEB + JavaScript + Oracle database Implementation of LDAP at IN2P3: has been presented already by Hèlene Jamet IN2P3 global directory Roaming
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Present and future actions Looking for the other/new data storage technologies : STK 9840 (20 GB “Eagle”) MagStar mod E (20 GB cartridges) Tape servers : test with 43P 260 Xtage servers : test with SUN 450 (with Gigabit switch) or H50 (with Fast Ethernet) Batch : increasing capacity on AIX platform with B50 replacing the old 370
W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct Present and future actions Establish better support for the present and future big experiments (BaBar, D0, Star) Preparing the better support for data exchange for BaBar and D0 HPSS, Castor ?
