1. Jefferson Lab Site Report Kelvin Edwards Thomas Jefferson National Accelerator Facility Newport News, Virginia USA Kelvin.Edwards@jlab.org 757-269-7770 http://cc.jlab.org HEPiX - TRIUMF, Oct. 20, 2003

2. Central Computing Sun systems –Upgrade to Solaris 8 almost complete HP systems –All upgraded to HP 11i –Moving away from HP for central services Linux systems –Still at RedHat 7.2 –Evaluating RedHat 10 (Fedora 1) Windows 2000 Domain Upgrade –Implemented in May –Working on Group policy issues

3. Central Computing (cont) Network Appliance –2 recently upgraded to the FAS940 (~16k NFS Ops/sec) –~4.5TB online disk space (1.5TB home, 2TB group) Linux fileserver –3Ware SATA system –2TB scratch area (16 160GB Seagate SATA drives) Backups –QuickRestore –Seagate LTOs, Overland Tape Library

4. Scientific Computing JASMine & Auger (http://cc.jlab.org/scicomp) –JASMine: Mass Storage Tape + Disk Cache –Auger: Batch Farm Management & Monitoring –Typical Day 2 – 4 TB of INPUT data through the farm Process 2000 – 5000 jobs –Certificates used for all user authentication Tape drives –6 9840s – migrating data to 9940Bs –13 9940A – Read only –15 9940B – all data written to these tapes

5. Scientific Computing (cont) Linux File Servers –16 Data Movers – 10 Mylex eXtremeRAID 2000 RAID cards (RAID-5) (SCSI) 6 Adaptec 2200S Raid Cards (RAID-50) (U320 SCSI) –32 Cache/Work File Servers Mixture of Mylex and 3Ware cards Batch Farming – over 24000 SPECint95, LSF 178 RH 7.2 Linux dual-processors (P2 750 to P4 2.66GHz)

6. Noteworthy Kswapd failures -- Solved –Automount timeouts set to 60 seconds, NOT minutes Adaptec 2200S raid cards –Instead of the MegaRaid cards –Not quite as fast, but acceptable –Timeout problem -- fix available Adaptec TOE (TCP Offloading Engine) –Problems with RH7.2, custom kernel (XFS), and their driver –Anyone else using them? Good results?

7. Projects Windows –Standard builds (Server, IIS, desktop, laptop) Backup Software Upgrade –Reliaty (was QuickRestore) SSH v2 Internally Networks –Gigabit connection to our border router –VLans for use on site

8. Projects (cont) JASMine –Rewrite disk cache –Support farm output caches –Policy-based file movement off-site Auger –Better file scheduling/pinning

9. Projects (cont) PPDG –SRM version 2 –Replication Replica Catalog web service interface –Remote Job submission User and System JDLs Batch web service integration with Auger
