3. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 3 BAHIA - interactive front-end Introduction of multi-processors:  AIX 4.3.2 -> 6 * F40  HP-UX 10.20 -> 7 * HP9000/780/J282  Solaris 2.6 -> 3 * Ultra-4/E450  Linux (based on RedHat 5.2) -> 2 PentiumII450

4. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 4 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: 200000 UI/month, ~75% cpu

5. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 5 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

6. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 6 Networking - WAN  Project “Renater 2” based on virtual networking (ATM) with guaranteed bandwidth.  See the presentation of this project by Chafia Tifra.

7. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 7

8. 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).

9. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 9 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

10. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 10 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

11. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 11 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

12. W.A.Wojcik/CCIN2P3, HEPiX at SLAC, Oct 1999 12 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 ?
